https://doi.org/10.5278/ijsepm.3502 | INTRODUCTION: Why a Virtual Round Table on Innovation for Smart and Sustainable Cities? | Innovation is, according to the definition given in Innovation in Firms: A Microeconomic Perspective, OECD, 2009, the "implementation of a new significantly improved product, good, service, or process, a new marketing method, or a new organizational method in business practices, workplace organization or external relations". We know that innovation can be incremental -in terms of optimization of existing products, services or systems -or radical such as innovations which dramatically change social and business practices, and create new markets. Concerning the urban dimension, specifically sustainable urban development, it appears clear that incremental improvement, whilst potentially important, could not be sufficient to bring the required structural change. Cities are indeed the best place to experiment innovation as its societal dimension is characterized by a combination of technology, infrastructure, production systems, policy, legislation, user practices and cultural meaning. Moreover cities are interconnected social, technical and ecological systems made by people, infrastructures, buildings, flows, functions and services. Cities are the principle engines of innovation and economic growth. | [

https://doi.org/10.5278/ijsepm.3327 | Identification of user requirements for an energy scenario database | Energy scenarios assist decision making regarding the transformation of the energy supply system. A multitude of scenarios exists in various formats. Thus, for scientists and policy stakeholders alike, it remains difficult to distinguish and compare scenario data. Hence, the aim of the project SzenarienDB is to establish an energy scenario database containing data in comparable and machine-readable format. SzenarienDB will do so by extending the OpenEnergyPlatform (OEP). To ensure that the extension fulfils the requirements of the modelling community, we conducted an online survey. We asked the participants about what they expected of an energy scenario database. Along with input from expert meetings and GitHub issues on that topic, we derived user requirement from the answers. In total, we identified 69 requirements. Out of these, around 44% were considered as very urgent. Hence, we conclude that there is a great need for the development of a consistent energy scenario database. To tackle the requirements we grouped these into twelve categories: input and output, data review process, bug-fixes, documentation, factsheets, features, functions to modify data, layout, metadata, ontology, references, and other. Each category is resolved according to its intrinsic properties. | [

https://doi.org/10.5278/ijsepm.3328 | Interconnection of the electricity and heating sectors to support the energy transition in cities | The electricity, heating, and transport sectors in urban areas all have to contribute to meeting stringent climate targets. Cities will face a transition from fossil fuels to renewable sources, with electricity acting as a cross-sectorial energy carrier. Consequently, the electricity demand of cities is expected to rise, in a situation that will be exacerbated by ongoing urbanisation and city growth. As alternative to an expansion of the connection capacity to the national grid, local measures can be considered within city planning in order to utilize decentralised electricity generation, synergies between the heating and electricity sectors, and flexibility through energy storage technologies. This work proposes an optimisation model that interconnects the electricity, heat, and transport sectors in cities. We analyse the investments in and operation of an urban energy system, using the City of Gothenburg as an example. We find that the availability of electricity from local solar PV together with thermal storage technologies increase the value of using power-to-heat technologies, such as heat pumps. High biomass prices together with strict climate targets enhance the importance of electricity in the district heating sector. A detailed understanding of the integration of local low-carbon energy technologies can give urban planners and other city stakeholders the opportunity to take an active role in the city's energy transition. | [

null | Power accessibility, fossil fuel and the exploitation of small hydropower technology in sub-saharan Africa | This study overviews the power status, salient barriers to adequate power access and the role of small hydropower in improving power accessibility in the region. The study notes that -over 50% of the population in 41 countries in the region have no access to electricity; the prediction of electricity access growth rate in SSA from 43% in 2016 to 59% in 2030; about 607 people, which is 90% of world's population without access to electricity in 2030 will leave in the region and the rural areas access is below 20%; over 90% of the households in about 25 countries of SSA rely on waste, wood, and charcoal for cooking; the average grid power tariff in SSA is US$0.13 per kWh as against the range of US$0.04 to US$0.08 per kWh grid power tariffs in most parts of the developing world. Also, it was found that the sections of power supply system -generation, transmission and distribution facilities are affected by insufficient funding, poor maintenance and management and over dependence on foreign power supply technologies; and the region is endowed with huge SHP resource that is insignificantly tapped. Lack of workable SHP development framework; insufficient fund; effect of the electricity market in the region; lack of effective synergy among the stakeholders; insufficient and outdated hydrological information about SHP resources; inadequate human and manufacturing facility development were the identified factors responsible for SHP underdevelopment. Domestic development of SHP technology is required to effectively develop SHP to improve access to power in the region. This will require massive human capacity building and the use of locally soured materials and production facilities. | [

null | How can urban manufacturing contribute to a more sustainable energy system in cities? | The paper explores future opportunities as well as challenges arising from urban manufacturing (UM) regarding the design of sustainable energy systems for cities. Global trends affect the type of production (e.g. Industry 4.0) as well as the industrial structure (e.g. convergence of services and production) of UM in cities. This causes new requirements but also new options for the urban energy system. The study presented in this paper examines this area of tension and explores not only the potentials of waste heat use, but also additional electricity demand through steadily advancing digitalisation. The study illustrates, that over the next few years it will be key to improve the interfaces between actors and sectors: between companies ("energy communities"), between industry and grid/ energy supply company/neighbouring settlement areas and between the sectors heat-electricitygas-mobility through e.g. power-to-x and possible uses of hydrogen. The paper concludes with a concept for integrating urban manufacturing optimally in the urban energy system for a sustainable energy transition in the future. | [

null | Methodology to characterize a residential building stock using a bottom-up approach: a case study applied to Belgium | In Europe, the residential sector accounts for 27% of the final energy consumption[1], and therefore contributes significantly to CO 2 emissions. In the context of mitigation of climate change, roadmaps towards energy-efficient buildings have been proposed [2] and detailed characterizations of residential building stocks and end-user consumption are of major importance. Swan and Ugursal [3] identified two methods in their review of modeling techniques of end-use energy consumption in the residential sector: top-down and bottom-up. In the top-down approach, the residential sector is seen as an energy sink. The consumption is based on widely available macroeconomic variables as well as on climate conditions, appliances ownership and | [

null | National Energy and Climate Planning in Serbia: From Lagging Behind to an Ambitious EU Candidate? | Just in the immediate neighbourhood of the European Union (EU), the Republic of Serbia, one of the Western Balkan (WB) EU candidate countries, is lagging behind in the process of energy transition regardless of technological advances and policy instruments available. The EU created a momentum for energy transition acceleration with the European Green Deal, which has been forwarded to the WB through the Energy Community secretariat in the form of the Green Agenda; generally speaking, response in the form of National Energy and Climate Plans (NECPs) is expected in the short term. The Republic of Serbia's Low Carbon Development Strategy with Action Plan (LCDSA) and the current Energy Strategy will be analysed, commented on, and improvements will be suggested for the acceleration of energy transition, based on the newest findings from the simulation-based optimization techniques using the sector coupling approach to achieve ambitious variable renewable energy shares. The motivation of this research is to provide decision makers in Serbia with the best available insights regarding sustainable energy system planning tools and possible shortcuts for delayed planning of activities. In addition, the purpose is to improve Serbia's chance of benefitting from adoption of these strategies in the country's faster transition towards EU membership. The research compares two scenarios to illustrate a possible policy shift from small hydro power plants to photovoltaics (PV). A further increase in PV and wind power plants has been simulated using the EnergyPLAN to achieve expected scenarios of 40% renewable energy share and some more ambitious ones-up to 80%, which is realistic only with the sector coupling approach. | [

https://doi.org/10.5278/ijsepm.2018.17.5 | Assessment of a climate-resilient and low-carbon power supply scenario for Rwanda | Renewable energy sources are playing a key role in the transition to a low-carbon based economy while maintaining cost and environmental effectiveness. However, climate change threatens this opportunity especially in countries like Rwanda where more than half of the total supplied electricity in the country comes from hydropower. This study assesses the evolution of Rwanda's electricity demand towards 2050 and suggests a power supply scenario that considers impacts of climate change on the country's hydropower generation. The study findings indicate that to meet the projected demand under the Business As Usual (BAU), more than 20% of electricity requirements would come from imported more polluting fossil fuels. Under the suggested alternative scenario, however, no fossil fuels will be needed by 2050. Furthermore, the average emissions for the 2012-2050 period are estimated at 116 gCO 2 eq/kWh for the alternative scenario and 203 gCO 2 eq/kWh for the BAU scenario. Based on the findings of the study, it is concluded that the developed alternative scenario is resilient since it meets the projected demand when impacts of climate change are accounted for. Moreover, the scenario ensures the security of the country's electricity supply because it only relies on domestic energy resources. Furthermore, the suggested scenario positions the country to a low-carbon development pathway compared to the existing power supply plans. | [

Several linear and non-linear models, with and without air infiltration, are investigated and compared. The models are formulated using stochastic differential equations and the model parameters are estimated using a maximum likelihood technique. Based on the maximum likelihood value, the different models are statistically compared to each other using Wilk's likelihood ratio test. The model showing the best performance is finally verified in both the time domain and the frequency domain using the auto-correlation function and cumulated periodogram. The proposed model which includes air-infiltration shows a significant improvement compared to previously proposed linear models. The model has subsequently been used in applications for provision of power system services, e.g. by providing heat load reduction during peak load hours, control of indoor air temperature and for generating forecasts of power consumption from space heating. | [

null | Transition toward a fully renewable-based energy system in Chile by 2050 across power, heat, transport and desalination sectors | Renewable energies will play a significant role in transitioning towards sustainable energy system in order to match the goal under the Paris Agreement. However, to achieve this goal, it will be necessary to find the best country pathway, with global repercussions. This study reveals that an energy system based on 100% renewable resources in Chile would be technically feasible and even more cost-efficient than the current system. The Chilean energy system transition would imply a high level of direct and indirect electrification across all sectors. Simulation results using the LUT Energy System Transition model comprising 108 technology components show that the primary electricity demand would rise from 31 TWh to 231 TWh by 2050, which represents about 78% of the total primary energy demand. The remaining 22% would be composed of renewable heat and bioenergy fuels. Renewable electricity will mainly come from solar PV and wind energy technologies. Solar PV and wind energy installed capacities across all sectors would increase from 1.1 GW and 0.8 GW in 2015 to 43.6 GW and 24.8 GW by 2050, respectively. In consequence, the levelized cost of energy will reduce by about 25%. Moreover, the Chilean energy system in 2050 would emit zero greenhouse gases. Additionally, Chile would become a country free of energy imports. | [

https://doi.org/10.5278/ijsepm.3616 | Analysis of social inequality factors in implementation of building energy conservation policies using Fuzzy Analytical Hierarchy Process Methodology | Because residential buildings consume significant reserves of energy, they are among the largest contributors to climate change. Carbon and greenhouse gas (GHG) emissions from buildings have negatively impacted the environment. In response, institutions around the globe have issued policies and regulations to minimize climate change problems. While these policies have succeeded to some extent, additional factors are present that need greater attention. Among these other factors are social inequality and environmental injustice in society, both of which must be analyzed thoroughly before solutions can be suggested. This research seeks to examine these factors and their effects; we analyze the factors that cause social inequality and injustice and correlate those factors to the implementation of energy policies. We then pursue how these actions have consequences in civil society. Results show that some 15 social inequality factors are omnipresent, but the top three include: i) the limited participation of women in environmental campaigns, ii) variances in the adoption of building energy regulations across the globe, and iii) ethnic/racial discrimination with regard to how environmental safety is prioritized. We analyze these factors through the Fuzzy Analytical Hierarchy methodology (AHP), and our results are statistically validated through sensitivity analysis and a consistency check. | [

The alternative power-supply options proposed by governments in the region require appropriation analysis for selection. Four public housing estates in suburban Abuja are selected for electricity demand analysis under conventional and energyefficient lighting scenarios; then techno-economic parameters of two off-grid electric power supply systems (PV and Diesel-powered generation) to meet these electricity demands are evaluated. An energy techno-economic assessment methodology is used. The study determines the energyefficient lighting system is appropriate with 40% energy savings relative to the Conventional Lighting Systems. The diesel generator alternative power-supply option has Life Cycle Costs almost 4 times those of the PV option. The study established the PV-energy-efficient lighting system as the most feasible off-grid electric power supply alternative for implementation.

null | Trash to Hryvnias: The economics of electricity generation from landfill gas in Ukraine | Utilization of landfill gas for electricity generation should be an attractive option for Ukraine in light of the country's rapidly growing municipal solid waste problem, the influx of intermittent renewable electricity into the national grid, and renewable energy adoption commitments. However, the deployment of landfill gas power plants has been slow vis-à-vis other alternative energy technologies despite the existing government incentives. This article aims to help understanding this trend by investigating the economic feasibility of landfill gas power plants. The research focuses on determining the Levelized Cost of Electricity of these electricity generation facilities and comparing it to the feed-in tariff available to landfill gas electricity producers. The results show making an investment into a landfill gas-fired power plant is an appealing strategy due to a potential high and quick return on investment in 5.1 years. This leads to the ultimate conclusion that economic feasibility is not a cause for the slow adoption of landfill gas as a source of renewable electricity generation in Ukraine. In addition, the article identifies several potential barriers to landfill gas electricity generation deployment to be investigated in future research. | [

https://doi.org/10.54337/ijsepm.7477 | An Adaptive Staggered Investment Strategy for promotion of residential rooftop solar PV installations in India | Rooftop solar PV in India has seen good progress in the commercial and industrial sectors, but the progress in the domestic sector is relatively slow due to the high initial installation cost. Thus, there arises the need for good market models for Rooftop Solar (RTS) implementation. This paper conducts a comparative study of workable RTS market models by employing the discounted cash flow method, as per the recent regulatory guidelines. Market models are formulated and tested for a typical residential high-rise apartment complex in India comprising 15 storied buildings with a combined maximum demand of 180kVA. The results suggest that the centralized community RTS model of 80kWp capacity with upfront financing is suitable when compared to the decentralized individual model, as it has the lowest levelized cost of 3.39 ₹/kWh and a payback period of 5.5 years. With the federal subsidy, the prosumer levelized cost reduces to 2.06 ₹/kWh with a payback period of 3.3 years. Thus grid parity is achieved for all tariff tier rates. With adaptive staggering strategy, this scheme is validated to be more attractive for the urban residential microgrids, as the solar installation of 80kWp and its cost can be staggered and even reduced over the planning period. The study result gives RTS stakeholders insight into selecting the most cost-effective market model to suit their requirements. The proposed analysis can be replicated for high-rise residential buildings, especially in cities with high electricity tariffs. With time, a decrease in solar PV installation price and an increase in grid price are expected; hence, the overall investment cost gets reduced and staggered. | [

Stricter emission limits, decreased efficiency due to old age and increased costs are major challenges of the lignite sector and are expected to result in the decommissioning of several lignite-fired units in the coming years. As a result, managers of DH networks are currently investigating alternative scenarios for the substitution of thermal power that it is expected to be lost, through the integration of RES into the system. In this paper, the DH systems of Kozani and Ptolemaida are examined regarding possible introduction of RES.

null | Oil price and economic growth in Kenya: A trivariate simulation | The objective of this study is to empirically examine the dynamic causal relationship between oil price and economic growth in Kenya during the period from 1980 to 2015. In an effort to address the omission-of-variable bias, a trivariate Granger-causality framework that incorporates oil consumption as an intermittent variable between oil prices and economic growth -is employed. Using the newly developed autoregressive distributed lag (ARDL) bounds testing approach to cointegration and the Error-Correction Model-based Granger-causality framework, the results of the study reveal that there is distinct unidirectional Granger-causality flowing from economic growth to oil price in the study country. These results are found to apply both in the short run and in the long run. Thus, it can be concluded that in Kenya, it is the real sector that pushes oil prices up. Further, it is possible to predict oil price changes in Kenya -given the changes in economic growth. | [

https://doi.org/10.5278/ijsepm.5400 | Application of a cost-benefit model to evaluate the investment viability of the small-scale cogeneration systems in the Portuguese context | Increasingly, modern society is dependent on energy to thrive. Remarkable attention is being drawn to high energy-efficient conversion systems such as cogeneration. Energy sustainability depends on the rational use of energy, fulfilling the demands without compromising the future of energy supply. The market trends foresee the use of decentralized production and the increasing replacement of conventional systems by small-scale cogeneration units as solutions to meet the energy needs of the building sector. Analysing the influence of the variables that determine the economic viability of decentralized energy production systems has become more important given the scenario of energy dependence and high energy costs for the final consumer. A Cost-Benefit Analysis (CBA) was developed and presented to identify the potential of small commercial scale cogeneration systems in the Portuguese building sector, based on cost-benefit analysis methodology. Five case-scenarios were analysed based on commercial models, using different technologies such as internal combustion engines, gas turbines and Stirling engines. A positive value of CBA analysis was obtained for all the tested cases, however, the use of classic economic evaluation criteria such as the net present value, internal rate of return and payback period results led to different investment decisions. According to the results, the gas turbine has the best result of the CBA analysis in terms of annual profit (23 883 €/year), whereas, the SenerTec GmbH motor engine is the system with the highest specific profit (477.1 €/kW el ). For all the tested cases, the costs of the system operation exceed the profit from selling the generated electricity. Without accounting for the avoided costs and societal benefits, the CBA results would disclose unprofitable cogeneration systems. The model also highlights the influence of energy prices in the economic viability of these energy power plants. The inclusion of subsidized tariffs for efficient energy production is the most contributing aspect in the analysis of the economic viability of small-scale cogeneration systems in the Portuguese building sector. Only in that case, it would be possible for an investor to recover the capital costs of such technology, even if the technical and societal benefits are accounted for. | [

https://doi.org/10.5278/ijsepm.3824 | Review of price regulation regimes for district heating | Europe is facing a great technical and regulatory challenge in transitioning the energy supply from fossil fuels to sustainable renewables. Within the heating sector, the Heat Roadmap Europe studies have demonstrated great potential and benefits from expanding district heating (DH) throughout the continent. However, as a monopoly structure, DH grids require well-thought-out regulatory regimes to be accepted by cities and consumers. Effective regulation must safeguard consumers against misuse of monopoly prices and set the right incentives to enhance efficiency and to introduce new technologies. Founded upon the approach of concrete institutional economics, this paper contributes to the literature on DH regulation by reviewing and describing regulatory experiences in Denmark and other countries. This article demonstrates that a wide range of regulatory mechanisms are available for implementing DH and describes how regulation must take into account whether the DH companies are privately or publicly owned by municipalities or consumer groups. DH is typically a monopoly supply, which may result in higher consumer prices if proper regulation is not in place. Both privately and publicly owned DH supplies must be guided by various efficiency-enhancing measures. Regulated prices and the use of benchmarks must be carefully prepared in order to work by the book in an often-complicated organisational set-up. The use of private enterprises to develop and operate a public DH enterprise must involve the establishment of proper incentives and performance measures in the contract, etc. A mix of price-setting regimes and ownership models can be determined. The choice of model may depend on the specific circumstances, considering, among other concerns, the scale of the heat market, the local availability of waste heat, existing ownership of housing, access to (cheap) financing, a stable regulatory framework, and confidence-building measures for commercial or public investors. | [

https://doi.org/10.5278/ijsepm.2016.9.3 | Estimation of the Global Solar Energy Potential and Photovoltaic Cost with the use of Open Data | There is an increasing demand for renewable electricity sources, due to the global efforts to reduce CO 2 emissions. Despite the promising effects, only a limited amount of electricity is currently produced globally from solar power. In order to help countries realize the importance of tapping into solar energy, it is crucial to reveal the potential amount of electricity that could be thus produced. For this reason, open data were used to produce an interactive web map of the global solar energy potential. For the calculation of the potential, the top-down approach, generally used in the literature, was modified by introducing a better way of calculating rooftop areas, and accounting for temperature, which highly reduces PV panels' efficiency. Mean annual temperature data were introduced to improve its accuracy, and an approach to estimate rooftop and façade areas as a function of GDP was developed. The current global solar potential technically available was estimated at about 613 PWh/y. Furthermore, the cost of photovoltaic generation was computed and extremely low values, 0.03 -0.2 $/kWh, were derived. | [

null | Increased demand-side flexibility: market effects and impacts on variable renewable energy integration | This paper investigates the effect of increased demand-side flexibility (DSF) on integration and market value of variable renewable energy sources (VRE). Using assumed potentials, systemoptimal within-day shifts in demand are investigated for the Northern European power markets in 2030, applying a comprehensive partial equilibrium model with high temporal and spatial resolution. Increased DSF is found to cause only a minor (less than 3%) reduction in consumers' cost of electricity. VRE revenues are found to increase (up to 5% and 2% for wind and solar power, respectively), and total VRE curtailment decreases by up to 7.2 TWh. Increased DSF causes only limited reductions in GHG emissions. The emission reduction is, however, sensitive to underlying assumptions. The study shows that increased DSF has the potential of improving intergration of VRE. However, low consumers' savings imply that policies stimulating DSF will be needed to fully use the potential benefits of DSF for VRE integration. | [

https://doi.org/10.5278/ijsepm.3340 | Low-temperature district heating networks for complete energy needs fulfillment | In order to reduce fossil fuels consumption and pollutant emissions, high contribution is given by district heating. In particular, the integration with renewable energy may lead to a significant increase in energy conversion efficiency and energy saving. Further benefits can be achieved with low temperature networks, reducing the heat dissipations and promoting the exploitation of low enthalpy heat sources. The aim of the paper is the analysis of the potential related to the conversion of existing district heating networks, to increase the exploitation of renewables and eliminate pollutant emissions in the city area. Further aim, in this context, is the optimization -from both energy production and operation management viewpoints -of a low temperature district heating network for the fulfillment of the connected users' energy needs. To this respect, a traditional network with a fossil fuel driven thermal production plant has been considered and compared with a low temperature district heating scenario, including geothermal heat pumps, photovoltaic panels and absorption chillers. These scenarios have been analyzed and optimized with a developed software, demonstrating the reduction of primary energy consumption and CO 2 pollutant emissions achievable with low temperature networks. In addition, a preliminary economic comparative evaluation on the variable costs has been carried out. Future studies will investigate the economic aspect also from the investment costs viewpoint. | [

null | The Impact of Local Climate Policy on District Heating Development in a Nordic city -a Dynamic Approach | On a national level, Sweden has announced plans to have no net emissions of greenhouse gases in 2045. Furthermore, Gothenburg, a city in southwestern Sweden, has plans to phase out the use of fossil fuels in its heat and electricity production by 2030. Given that the development of a district heating (DH) system under dynamic and different climate policies and climate goals is a nontrivial problem, this study investigates two different policies of phasing out fossil fuels, either by introducing a fossil fuel ban, or by increasing the carbon tax to phase out the fossil fuel use in 2030 or 2045. The effects of the different phase out strategies on the future development of the existing DH system in Gothenburg has been investigated. The study is based on a system-wide approach covering both the supply and demand side developments. A TIMES cost optimizing energy system model representing the DH system of Gothenburg was developed and applied for calculations. The results show that the total amount of heat supplied by the DH system is unaffected by the phase out policies. The amount of natural gas used to supply the DH system is however dependent on what kind of phase out policy is implemented. A yearly increasing carbon tax policy introduced in 2021 phases out fossil fuel use earlier than the target year, while a ban phases out the fossil fuel only from the actual target year. | [

null | Methodology to design district heating systems with respect to local energy potentials, CO 2 -emission restrictions, and federal subsidies using oemof | To combine a variety of different heat generating technologies, static design methods will not be sufficient to design future heat supply systems. New energy system design approaches are being developed with consideration of fluctuating renewable energy sources, different subsidy measures, as well as CO 2 -emission reduction targets. The motive of this study is to develop a new methodology to design and optimise an energy system considering these constraints. The methodology is developed based on the Open Energy Modelling Framework (oemof) and applied on a sub-urban region in northern Germany. Local specifics of energy source potentials are taken into account. It adapts the boundary conditions of a German federal funding program for innovative heat supply networks "Heating Network Systems 4.0." Federal funding restrictions of combined heat and power systems and selfconsumption are also considered. An economic optimisation was conducted considering a variety of energy sources. Cost optimal energy system design was computed regarding investments costs, energy prices and annual CO 2emission restrictions. The integration of combined heat and power (CHP), photovoltaic (PV) and heat pump (HP) systems in combination with storage size optimisation can reduce CO 2 -emission of heat production by approx. 69% compared to the current state of heat production. | [

This study aims to propose a Participatory Process Protocol to enhance the output of energy plans and projects through the effective engagement of local stakeholders. A knowledge transfer methodology is set to build on a successful experience of the Mediterranean port-cities of Málaga, Cádiz and Sète, now adapted into the case of European Union's islands advancing with energy developments. First, a clustering analysis is carried out for inhabited islands, resulting in 4 clusters that serve as the classification for the calculation of energy transition Key Performance Indicators according to information received from 70 islands. Based on this, the original Protocol is restructured as a complement for the Sustainable Energy and Climate Action Plan methodology, the one most adopted by European islands. Finally, how the Protocol might be implemented depending on the particularities of each cluster is discussed, as well as for the case of Spanish islands (Gran Canaria, Tenerife, and La Palma). Specific suggestions and key recommendations for the implementation of the Participatory Process Protocol are mentioned, as an instrument that could raise strategic suggestions from stakeholders to enhance the results of decision-making processes. | [

Policymakers highly encourage the use of GIS software at all administrative levels. It is expected that the heating and cooling demand will continue to increase. For a reliable heat and cooling supply, we must identify heat sources that can be used to provide heat or for removing surplus heat. We propose a method for identifying possible heat sources for large heat pumps and chillers that combines geospatial data from administrative units, industrial facilities, and natural bodies of water. Temperatures, capacities, heat source availability, as well as their proximity to areas with high demand density for heating and cooling were considered. This method was used for Estonia, Latvia and Lithuania. Excess heat from heat generation plants and industries, sewage water treatment plants, and natural heat sources such as rivers, lakes and seawater were included. The study's findings provide an overview of possible industrial and natural heat sources, as well as their characteristics.

https://doi.org/10.5278/ijsepm.5843 | Energy system optimization including carbon-negative technologies for a high-density mixed-use development | In this paper, we use the 'energy hub' optimization model to perform a multi-objective analysis on a high-density mixed-use development (termed the 'mothership') under different scenarios and compare these results to appropriate base cases. These scenarios explore how the optimal energy system changes under different assumptions, including a high carbon tax, net metering, net-zero emissions and negative emissions, as well as two different electrical grid carbon intensities. We also include 'carbon negative' technologies involving biochar production, to explore the role that such processes can play in reducing the net emissions of energy systems, The annualized cost and total emissions of the mothership with a simple energy system are 4 and 8.7 times lower respectively than a base case using single detached homes housing the same population, due to the more efficient form and hence lower energy demand. Of the scenarios examined, it is notable that the case with the lowest annualized cost was one with a net-zero carbon emissions restriction. This gave an annualized cost of CAD 2.98M, which 36% lower than the base case annualized cost of CAD 4.66M. This relied upon the carbon negative production and sale of biochar. All scenarios examined had lower annualized costs than the base cases with many of the cases having negative operating costs (generating profit) due to the sale of renewable energy or carbon credits. This illustrates that the integration of renewable energy technologies is not only beneficial for reducing emissions but can also provide an income stream. These results give hope that suitably optimized urban developments may be able to implement low cost solutions that have zero net emissions. | [

Although citizens' interest in the use of renewable resources has gradually grown, energy policy support measures for more active participation of society in the implementation of energy efficiency measures are still being implemented with variable success, especially through mutual agreement. Serious games are a rapidly growing tool for awareness and collaboration on a single platform for gamers seeking solutions to energy resource optimization issues. The main focus of the article is on the opportunities offered by a newly developed simulation tool for promoting the development of energy communities and the experience gained by its users. The tool's description and simulation results provide new information and knowledge for those working in the serious gaming field. The proposed solution promotes the development of new methods (tools) for decision-making processes based on serious games. This study uses a multi-player simulation tool to enable the modelling of scenarios for energy efficiency measures for apartment building block residents and energy community target goals for decision-making decisions.

https://doi.org/10.5278/ijsepm.6657 | The role of small-scale and community-based projects in future development of the marine energy sector | Despite high expectations for the sector, most marine energy technologies remain in the research and development, or at best demonstration, phase. The industry is in a period of stagnation, and requires new approaches to overcome the challenges that inhibit widespread deployment. Smallscale initiatives have proven to be a successful means of developing other renewable technologies but their role in supporting marine energy is not well researched. This paper provides a review of the barriers and opportunities presented by different policy landscapes, financial support mechanisms, markets, key actors, and wider regulatory and governance issues. Semi-structured interviews with marine energy stakeholders from the UK, Canada and Denmark were used to explore the role of small-scale marine energy projects, and were supplemented by interviews with the general public in England. This showed that while marine energy is appropriately scalable for local projects, financing remains a major hurdle. Discretionary local authority finance, as well as other novel options such as crowdfunding, tends to be relatively modest, supporting the argument for small-scale projects. A market for smaller devices exists, particularly for remote communities currently dependent on expensive energy from oil-fired generators. There remains a significant role for small-scale projects in testing the technology, contributing to reductions in cost and environmental risk. Current processes for environmental impact assessment can present a significant hurdle for small projects, but proportionate, adaptive assessments are evolving. Finally, community ownership and public participation have the potential to increase advocacy for the industry, with multi-actor partnerships presenting a positive way forward. | [

The study employed the Fully Modified Ordinary Least Square and Canonical co-integration regression techniques using data from 1975-2013. Among other results, the study revealed that income and urbanization increased fossil fuel consumption for all the countries. Also, while trade reduced fossil fuel consumption for Kenya and South Africa, the opposite was found for Ghana. In addition, the efficiency of the service sector reduced fossil fuel consumption for all the countries. The results of the study suggest efforts should be geared towards strengthening the energy efficiency system in each of these countries to help reduce fossil fuel consumption. Also, it is necessary that tariff and non-tariff barriers on products that do not promote energy efficiency is raised and vice versa, inter alia. | [

null | GIS methodology and case study regarding assessment of the solar potential at territorial level: PV or thermal? | This paper presents a GIS-based methodology for assessing solar photovoltaic (PV) and solar thermal potentials in urban environment. The consideration of spatial and temporal dimensions of energy resource and demand allows, for two different territories of the Geneva region, to determine the suitable building roof areas for solar installations, the solar irradiance on these areas and, finally, the electrical and/or thermal energy potentials related to the demand. Results show that the choice of combining PV and solar thermal for domestic hot water (DHW) is relevant in both territories. Actually, the installation of properly sized solar thermal collectors doesn't decrease much the solar PV potential, while allowing significant thermal production. However, solar collectors for combined DHW and space heating (SH) require a much larger surface and, therefore, have a more important influence on the PV potential. | [

null | European Union funding Research Development and Innovation projects on Smart Cities: the state of the art in 2019 | European cities currently host 72% of the European population, which probably will rise to 80% by 2050. European Union, Member States, National and Regions Authorities and different type of stakeholders have worked -and keep on doing -together to promote a sustainable urban development and to adapt policies to the needs of cities, thus make visible improvements to the daily lives of people. According to this approach, many Member States decided to pool resources at european level, achieving more than by acting alone. It is thanks to the coordinated approach of European Union and Member State that Research Development & Innovation boost smart cities and smart specialization strategies as two novelties that have been adopted by policymakers. priority for the effective implementation of Europe itself. Although European cities play a key role in the life of Europeans, it seems almost incongruent and senseless that there is no common definition for "urban" or even for "city", and that the European Union has no explicit jurisdiction in urban development, as urban planning per se is not a European policy competence even if economic, social and territorial cohesion all have a strong urban dimension. Therefore, even if the "European model of the city" is a fascinating issue, it is clear that there is no need to adopt a single definition. However, it is possible to move towards a shared European vision of urban development, as noted by the paper "Cities of Tomorrow" (DG Regional Policy, 2011) which consider | [

null | Ranking of energy sources for sustainable electricity generation in Indonesia: A participatory multi-criteria analysis | An evaluation of energy sources for electricity generation should consider manifold aspects of the sustainable development concept. The evaluation also needs active participation from all involved stakeholders. The objective of this paper is to rank energy sources for sustainable electricity generation in Indonesia. A multi-criteria decision analysis using the analytic hierarchy process method was applied to deal with multiple aspects of the sustainable development in the ranking of selected energy sources. Four criteria, twelve sub-criteria and nine energy source alternatives (three fossil fuels and six renewables) were defined. Relevant Indonesian energy stakeholders from government institutions, universities, think tanks, the energy industry, civil society and international organisations participated in this research. They gave judgements on pair-wise comparisons of the criteria and sub-criteria and a performance evaluation of the alternatives against four sub-criteria. The performance of the alternatives against the other eight sub-criteria was evaluated using data from relevant literature. This paper indicates that solar is the top ranked alternative for sustainable electricity generation in Indonesia, followed by hydro and oil as the top three. To fulfil the solar energy potential, the Indonesian government should consider policies that focus on the strengths of solar in the economic and social criteria. | [

null | District heating distribution grid costs: a comparison of two approaches | Since the introduction of the effective width concept for the estimation of the linear heat density, it has been frequently used by researchers to calculate district heating distribution grid costs in pre-feasibility phases. Some researchers, however, still prefer using a detailed modelling approach to get reliable results. This paper aims to highlight the advantages, disadvantages, and challenges of using the effective width concept to calculate district heating distribution grid costs compared to a detailed, optimisation-based modelling approach such as DHMIN. The outcomes of this paper reveal that although there are differences in obtained indicators such as trench length or distribution gird costs, both approaches deliver very similar patterns in different areas with various heat demand densities and plot ratios. Furthermore, it was revealed that for getting reliable results for a given case study, the input parameters and cost components should always be tuned to that case study regardless of the approach used. | [

null | Smart Energy Aalborg: Matching end-use heat saving measures and heat supply costs to achieve least-cost heat supply | Energy efficiency improvements of buildings is widely recognized as an important part of reaching future sustainable energy systems, as these both reduce the need for energy and improve the efficiency of the heat supply. Finding the correct level of efficiency measures, depends on the type of measure, on the supply system typology as well as on the heat supply cost. As this information is often building-specific, most analyses related to energy efficiency in buildings are carried out in relation to specific renovation projects, while energy plans for larger areas make crude assumptions regarding levels of savings and costs. This article aims at improving the latter, by using a detailed heat atlas in combination with specific marginal energy renovation costs, in a study of Aalborg Municipality in Denmark. In the analysis, all buildings in the municipality are mapped at building level and both the marginal energy efficiency measure costs and the marginal heat supply costs are identified. The buildings are then sorted by their supply type, and marginal costs curves on supply and savings are compared to determine the feasible level of efficiency measures in each building. The results show that both the building type and the supply costs have a large influence on the feasible measures. Furthermore, the results show that a demand reduction of 30% in district heating areas, 35% for buildings with heat pumps and 37% for buildings with oil boilers, for the examined buildings, is socio economically feasible in a Business as Usual 2050 Aalborg Municipality scenario. | [

null | Classification through analytic hierarchy process of the barriers in the revamping of traditional district heating networks into low temperature district heating: an Italian case study | The revamping of existing high temperature district heating systems with low temperature solutions will ensure a better usage of primary energy thanks to the reduction of thermal losses through the networks and to the possibility of using low grade enthalpy heat for the purpose, including renewables and waste heat. However, several criticalities are present that make the evolution from the 3 rd to the 4 th generation of district heating not immediate. The paper aims to identify general technological and non-technological barriers in the revamping of traditional district heating networks into low temperature ones, with a particular focus on the Italian framework. Possible solutions are suggested, including relevant advice for decision makers. The paper also analyses how the possible solutions required for the up-grade of the existing district heating network can be classified through the Analytic Hierarchy Process (AHP) to prioritize the ones that prove best for more advanced evaluation. | [

null | Integrating energy markets: Implications of increasing electricity trade on prices and emissions in the western United States | This paper presents empirically-estimated average hourly relationships between regional electricity trade in the western United States (US) and prices, emissions, and generation from 2015 through 2018. It provides new evidence of the short term impacts of integrating markets to inform electricity market policymakers. Consistent with economic theory, the analysis finds a negative relationship between electricity price in California and regional trade, conditional on local demand. Each 1 GWh increase in California electricity imports is associated with an average $0.15 per MWh decrease in the California Independent System Operator's (CAISO) wholesale electricity price. There is a net-negative short-term relationship between CO 2 emissions in California and electricity imports that is partially offset by positive emissions from exporting neighbors. Specifically, each 1 GWh increase in regional trade is associated with a net 70-ton average decrease in CO 2 emissions across the western U.S., conditional on demand levels. The results provide evidence that electricity imports mostly displace natural gas generation on the margin in the California electricity market. A small positive relationship is observed between short-run SO 2 and NO x emissions in neighboring regions and California electricity imports. The magnitude of the SO 2 and NO x results suggest an average increase of 0.1 MWh from neighboring coal plants is associated with a 1 MWh increase in imports to California. | [

null | Planning for a 100% renewable energy system for the Santiago Island, Cape Verde | Ensuring the supply of affordable energy, improving energy efficiency and reducing greenhouse gas emissions are some of the priorities of the governments of several countries. The pursuit of these energy goals has triggered interest in the exploration and usage of Renewable Energy Sources (RES), which can be particularly appropriate for island systems as is the case of Cape Verde. This work proposes a generation expansion planning model for Cape Verde considering a 20 years' period. Different scenarios were analysed, each one representing a possible RES contribution for electricity production, reaching a 100% RES share. The results demonstrate that the increase of the RES in the system will lead to an increase in the total system cost. However, a significant decrease in both CO 2 emissions and external energy dependency of the country is projected. The seasonality of the RES resources, and in particular of wind power is shown to be one of the most important challenges for the effective uptake of such a renewable power system. A least-cost solution might be possibly achieved if storage technologies would be considered within the modelling approach (e.g. battery and Power-to-Gas technologies) which would also contribute to accommodate the Critical Excess of Electricity Production (CEEP). While the proposed model allowed already to present some useful scenarios, it becomes also evident the need to expand the analysis by using hourly data and taking into account the sector's integration (e.g. power, heat and transport). | [

null | Investigating the cost-effective energy efficiency practices with mitigated rebound: the case of energy intensive industries | Energy efficiency enhancement is considered a solution for enhancing energy conservation and sustainability. The present study deals with two major challenges in improving energy efficiency: the initial investment cost and the rebound effect. Funding of energy efficiency solutions and mitigating the rebound can be achieved through energy subsidy reduction. To be an effective policy, there must be a plan that considers the dependency between energy efficiency, avoided subsidy, and required funds for all efficiency solutions. Thus, there is a problem at the aggregate level of the economy whose roots are in engineering details. The combination of a top-down dynamic general equilibrium model with a bottom-up efficiency improvement module is used to find the set of efficiency practices that should be realized in each period along with the required increase in energy prices. Choosing efficiency practices depends on their costs and the available funds that are retrieved from avoided subsidies in the previous period. The model is applied to the energy-intensive industries in Iran. The model results show that using the recommended policy, over less than ten years, the energy efficiency of electrical and natural gas equipment in energy-intensive industries of Iran can be increased by 12.7% and 18.1% respectively. The rebound effect starts with values above 80% and then falls below 0% which indicates the success of the proposed policy in mitigating the rebound effect. Results also demonstrate that the implementation of the policy realizes the 4% reduction in CO 2 emissions by 2030 which is Iran's unconditional pledge. | [

https://doi.org/10.5278/ijsepm.2017.13.4 | Costumer Perspectives on District Heating Price Models | In Sweden there has been a move towards more cost reflective price models for district heating in order to reduce economic risks that comes with variable heat demand and high shares of fixed assets. The keywords in the new price models are higher shares of fixed cost, seasonal energy prices and charging for capacity. Also components that are meant to serve as incentives to affect behaviour are introduced, for example peak load components and flow components. In this study customer responses to these more complex price models have been investigated through focus group interviews and through interviews with companies that have changed their price models. The results show that several important customer requirements are suffering with the new price models. The most important ones are when energy savings do not provide financial savings, when costs are hard to predict and are perceived to be out of control. | [

https://doi.org/10.5278/ijsepm.2015.7.8 | Energy Systems Scenario Modelling and Long Term Forecasting of Hourly Electricity Demand | The Danish energy system is undergoing a transition from a system based on storable fossil fuels to a system based on fluctuating renewable energy sources. At the same time, more and more of the energy system is becoming electrified; transportation, heating and fuel usage in industry and elsewhere. This article investigates the development of the Danish energy system in a medium year 2030 situation as well as in a long-term year 2050 situation. The analyses are based on scenario development by the Danish Climate Commission. In the short term, it is investigated what the effects will be of having flexible or inflexible electric vehicles and individual heat pumps, and in the long term it is investigated what the effects of changes in the load profiles due to changing weights of demand sectors are. The analyses are based on energy systems simulations using EnergyPLAN and demand forecasting using the Helena model. The results show that even with a limited short term electric car fleet, these will have a significant effect on the energy system; the energy system's ability to integrate wind power and the demand for condensing power generation capacity in the system. Charging patterns and flexibility have significant effects on this. Likewise, individual heat pumps may affect the system operation if they are equipped with heat storages. The analyses also show that the long term changes in electricity demand curve profiles have little impact on the energy system performance. The flexibility given by heat pumps and electric vehicles in the long term future overshadows any effects of changes in hourly demand curve profiles. | [

null | Accelerating Solar Power Generation to Achieve India's Net-Zero Goals: A Factor-Based Study | The commitment of India towards net-zero emissions, as announced at COP26, has led to remarkable transformations in its power sector. Despite being rich in diverse energy resources, India holds substantial potential for solar power generation, which is believed to play a crucial role in its journey toward net-zero emissions. Even though some states of India have achieved great milestones in the solar energy generation, still the progress seems insufficient and there exist regional imbalances. This shortage and imbalance may be attributed to various factors including fiscal, geographical and political elements. From the panel data analysis to identify the most influencing factors of solar power generation across 15 states, the cost of solar modules and the land availability were found to be the major drivers. The practical barriers associated with these factors are highlighted, and relevant potential solutions are proposed. The study insists on promoting rooftop solar as a viable alternative for small-scale initiatives and suggests altering the existing scheme, Pradhan Mantri Surya Ghar Muft Bijli Yojana, to ensure real monetary benefits for individuals through rooftop solar systems; progressive subsidy rates; regional subsidy ceilings; and zero-tax for solar PV modules; To facilitate large-scale solar projects, the concept of district-level green land banks has been proposed in the study. | [

null | Energy efficiency in the building sector: a combined middle-out and practice theory approach | The building sector in Europe is a major energy consumer. Professionals such as architects and different building engineers play a crucial role in the technology adoption process. This study aims to contribute to the understanding of how and why energy efficiency measures are implemented by professionals in building renovations. Three renovation projects of a municipality-owned housing company in a middle-sized town in Sweden were followed. Methods applied for this case study are semi-structured interviews, participant observations and document analysis. An analytical framework is developed, by combining a middle-out perspective with social practice theory (SPT) to enhance the understanding of how and why energy efficiency measures are adopted during the studied renovation meetings. The middle professionals meet during a renovation and form a temporary constellation. The meeting practice endures because it is repeatedly enacted. One conclusion from the studied processes is e.g. that the aggregated know-how of the professionals are seldom discussed, with the consequence that tacit knowledge is not challenge or re-evaluated. By changing a meeting practice hinders to energy efficiency can be removed. | [

https://doi.org/10.5278/ijsepm.3354 | Simulation of an alternative energy system for district heating company in the light of changes in regulations of the emission of harmful substances into the atmosphere | In recent years, Poland has been going through many changes, also within energy generation and the legal and regulatory system. According to the EU 2020 Climate and Energy Package, in the nearest future the polish energy industry, will have to significantly modernize most of its power plants. The dynamically changing situation results in higher demand for various analysis (concerning both energy and economic aspect) helping with setting the frames for the future functioning of power engineering companies. One of the Polish power companies, PEC Legionowo, is reshaping its infrastructure to meet the new requirements and from this particular company, authors are using the acquired data for the test case. The first conceptual project related to the development of the PEC Legionowo energy system is currently being realized in terms of increasing its energy efficiency and reducing harmful exhaust emissions. Because PEC Legionowo is obligated to significantly reduce emissions by 2022, they are seriously considering reducing coal-based production. The resulting energy gap is planned to be covered by among others installing high-efficiency combined heat and power (CHP) systems. This article analyzes and verifies the model of an existing CHP plant and checks the modernization possibilities of the existing installation in terms of reducing emission. The new installation of gas boilers designed to replace coal-fired boilers is being validated, to meet the new emission requirements while still meeting the demand for heat and electricity. For modelling a test case, the combined techno-economic optimization and analysis software energyPRO is used. The software optimizes the operation of the modeled system according to all input conditions, such as generation and economic data obtained from a functioning CHP plant in the Polish industry. The results show the quantitative and economic difference related to the introduced changes in the heat and power plant system. The analysis also focuses on the size of the investment outlay and the return time of the project. | [

null | Knowing electricity end-uses to successfully promote energy efficiency in buildings: a case study in low-income houses in Southern Brazil | The objective of this paper is to show the importance of measuring electricity end-uses in order to promote energy efficiency in low-income houses in Southern Brazil. Sixty low-income houses were surveyed, and data of socioeconomic variables, electricity use, and usage pattern were measured and obtained. Confidence intervals were assigned to obtain representative electricity end-uses and usage patterns. The results showed that the electric shower has the greatest electricity end-use, i.e., 33.5 to 40.3%, followed by the refrigerators, with end-use of 27.4 to 33.1% with 90% non-parametric confidence interval. Usage patterns were obtained for appliances and lighting for each room and also for the electric shower. The results of this study will provide basis for determination of guidelines for low-income houses and government programmes for energy efficiency, rational use of energy and renewable energy. | [

null | Evaluation of China's policy for wind power development from the new structural economics perspective | The Chinese energy transition, as a shift from fossil fuels to renewable energy sources, involves the dynamic growth of wind power's importance in a national energy mix. The development of the wind power industry in this country is intertwined with the implemented policies that translated to the significant increase in energy generation from this power source and the growth of trade volumes of wind power products. This research aims to review and analyse the China's policy that impacted wind power development in 2000-2019. The author aims to evaluate the efficiency of implemented policies and strategies from the perspective of the new structural economics assumptions and the revealed comparative advantage of the Chinese wind energy products. In addition to the review of scientific literature and policy documents, as well as analysis of the relevant trade and energy indicators, the method applied in this research is a calculation of the Revealed Comparative Advantage (RCA) index. The results provide pieces of evidence that despite the substantial development of the Chinese wind power industry on a national scale, this country still has not revealed a comparative advantage globally. However, the results also suggest that the Chinese wind power industry is on the right track to achieve export specialisation soon. Furthermore, the China's policy for wind power development matches the new structural economics assumptions. The presented insight into studied industry blazes the trail for other countries, which consider following the Chinese development path by shaping the growth of leading-edge industries and the energy transition process throughout various state interventions. | [

https://doi.org/10.5278/ijsepm.3831 | Comparative economic analysis for different types of electric vehicles | This study is dedicated to comparing the levelized operating costs of various types of power units and energy carriers for electric vehicles: battery systems, hydrogen-air fuel cells, and aluminumair electrochemical generators. The operating cost considers the power unit itself, energy carrier, and associated charging infrastructure. Each electric vehicle type was calculated in two versions: a passenger electric car and a light duty commercial truck. It is shown that the most cost effective power unit is an aluminum-air generator. Its levelized operating cost is 1.5-2 times lower toward a battery system and 3-4 times lower toward fuel cells. The advantage of aluminum as energy carrier is the low cost and simple design of the corresponding power unit and charging infrastructure compared to those for battery and hydrogen power units. Aluminum recycling is key to its efficient use, this concept may become competitive in the aluminum-producing countries. | [

null | Urban-rural relations in renewable electric energy supply -the case of a German energy region | So-called energy regions are one main driver in the transition towards 100% renewables on a local level. With their ambitious goals they strive for energy self-sufficiency based on their renewables potential. The model region consists of three municipalities (two rural regions and a mediumsized city) with the joint goal of 100% renewable electrical power supply in annual average by 2030. Based on the region's development path, this study predicts time-resolved renewable production and electrical demand profiles, including a sensitivity analysis on demand and generation profiles. In both rural regions renewable power production will exceed electrical demand while the city can only cover 27% of its power demand in 2030. The transition to renewable electricity supply of the city thus depends on its rural hinterlands. Synergetic crosslinking of urban and rural regions increases the total renewable electricity supply to 60 or 70%, depending on the size of the rural region considered. Seen from the perspective of rural regions cross-linkage to a city decreases the possible self-sufficiency compared to considering them as single regions. They can act as energy suppliers for neighbouring cities in the future. | [

https://doi.org/10.5278/ijsepm.2019.21.8 | A combined spatial and technological model for the planning of district energy systems | This paper describes a combined spatial and technological model for planning district energy systems. The model is formulated as a mixed integer linear program (MILP) and selects the optimal mix of technology types, sizes and fuels for local energy generation, combined with energy imports and exports. The model can also be used to select the locations for the energy sources, the distribution route, and optionally, to select the heat loads that will be connected to a district energy system. The optimisation model combines a map-based spatial framework, describing the potential distribution network structure, with a flexible Resource Technology Network (RTN) representation which incorporates multiple heat sources. Results for scenarios based on a test dataset are presented and show the impact of heat prices on the designed network length. The results illustrate the use of Combined Heat and Power (CHP) units to satisfy internal and external power demands, and also demonstrate their use in combination with heat pumps to satisfy emissions targets. A system value metric is introduced to quantify the incremental impact of investments in the heat network in areas of varying heat density. A procedure for screening potential supply locations to reduce computational requirements is proposed. | [

Unfortunately, the lack of information and widespread consumer ignorance of interconnections and dependencies in the district heating system (DHS) can lead to a situation where consumers are not interested in the development of the district heating system, or might even choose other heat sources. One of the possible solutions to provide information and educate consumers is a user-friendly, simplified mobile app that can show actual heat consumption structure, provide the possibility to compare the district heating supply with other heat supply solutions and provide information on how consumer behaviour affects the district heating system and how the district heating system transition towards the 4 th generation will change the primary energy consumption and CO 2 emissions. In this article, the authors present the concept and algorithm of a DHS promo mobile app that will be used at the national level in Estonia, that will allow consumers even with an insufficient amount of data available to each apartment/building owner to receive comprehensive information about the existing DHS and analyse how DHS improvements will affect the fuel mix and consumption amount required for heat supply per consume. | [

https://doi.org/10.5278/ijsepm.2018.18.5 | Economic benefits for producers of biogas from cattle manure within energy co-operatives in Ukraine | The paper deals with animal manure usage in order to produce biogas for energy generation in Ukraine. Although there are favorable conditions to develop the biogas sector based on animal manure, the share energy, which is produced from it, is extremely low (about 0.2% as of 2016). The paper analyzes energy potential of agricultural biomass in Ukraine, economic tools, aimed at stimulating electricity generation from biogas based on animal manure, the results of their impact on biogas plants deployment. Among a number of barriers, which slow down development of this sector in Ukraine, the main ones are the need for significant initial investments to construct profitable biogas plants and a large amount of raw materials for their uninterrupted operation. Given the fact that 48.2% of farm animals are concentrated in small-scale farms and households, which cannot individually implement biogas projects, it is proposed to combine their financial and raw material resources within energy co-operatives. Economic benefits, which may be gained by small-scale farms owners within energy co-operative through the sale of electricity, generated from biogas, by feed-in tariff are calculated. The results of research show that at the current level of feed-in tariff, the payback period of the biogas plant based on cattle manure, built within energy co-operative, is 4.6 years which is quite attractive for investors. It is discussed that in addition to economic benefits for small-scale farms owners, realization of the co-operative model in the bio-energy sector will create a number of ecological and social benefits both for local communities, and the state as a whole. | [

https://doi.org/10.5278/ijsepm.6710 | Pre-feasibility assessment for identifying locations of new offshore wind projects in the Colombian Caribbean | The offshore wind energy is showing a growing interest because of the increment of global energy demand and the commitment to reduce the CO 2 emissions. The need to identify new wind offshore areas has motivated the development of methods where several quantitative and qualitative factors are considered. Due to the variety of the identified factors is necessary establishing a priority order to know when they could be analyzed. The priorization of the identified factors not only ease the planning-execution of the future projects, but also economize resources because the achievement cost from the prefeasibility to final decision is ascendant, what means that the initial factors require less economic resources to be met compared to the factors grouped in the following stages. Then, this research organized the main factors in three stages (pre-feasibility, feasibility and final decision) and developed a methodology to perform a pre-feasibility analysis for identifiying potential offshore areas considering technicalenvironmental features and the wind characteristics in the space, time and frequency domain. The Colombian Caribbean coast was selected as study case, and the results pointed three areas and 10 locations with high potential for developing offshore wind projects. The north and central zone of the Colombian Caribbean coast were identified as the most suitable areas with mean annual wind speed over 10 m/s with low magnitude and direction variability, two factors considered extremely important for the wind power generation. | [

null | The role of 4 th generation district heating (4GDH) in a highly electrified hydropower dominated energy system -The case of Norway | District heating (DH) is considered an important component in a future highly renewable European energy system. With the turn towards developing 4 th generation district heating (4GDH), the integral role of district heating in fully renewable energy systems is emphasized further. Norway is a country that is expected to play a significant role in the transition of the European energy system due to its high shares of flexible hydropower in the electricity sector. While the country is moving towards electrification in all sectors and higher shares of variable renewable electricity generation, district heating could potentially decrease the need for electric generation and grid capacity expansion and increase the flexibility of the system. In this paper we investigate the role of 4GDH in a highly electrified future Norwegian energy system. A highly electrified scenario for the Norwegian energy system is constructed based on a step-by-step approach, implementing measures towards electrification and expansion of renewable electricity generation. Then, a 4GDH scenario is constructed for the purpose of analysing the role of 4GDH in a highly electrified hydropower based energy system. EnergyPLAN is used for simulation. Results show that an expansion of 4GDH will increase the total system efficiency of the Norwegian energy system. However, the positive effects are only seen in relation to the introduction of efficiency measures such as heat savings, more efficient heating solutions and integration of low-temperature excess heat. Implementation of heat savings and highly efficient heat pumps in individual based heating systems show a similar effect, but does not allow for excess heat integration. In the modelled DH scenario, the introduction of large heat storages has no influence on the operation of the energy system, due to the logic behind the EnergyPLAN model and the national energy system analysis approach chosen, and thus the effect of implementing 4GDH may be underestimated. | [

The improvement of the efficiency of vehicle energy systems promotes an active search to find innovative solutions during the design process. Engineers can use computer-aided processes to find automatically the best design solutions. This kind of approach named "multi-objective optimization" is based on genetic algorithms. The idea is to obtain simultaneously a population of possible design solutions corresponding to the most efficient energy system definition for a vehicle. These solutions will be optimal from technical, economic and environmental point of view. The "genetic intelligence" is tested for the holistic design of the environomic vehicle powertrain solutions. The environomic methodology for design is applied on D-class hybrid electric vehicles, in order to explore the techno-economic and environmental trade-off for different hybridization level of the vehicles powertrains. For powertrain efficiencies between 0.25 and 0.35 the electrification of the powertrain reduces the global CO 2 emissions. Hybrid electric and plug-in hybrid electric vehicles are reaching these levels. The break point of the electrification effect on the GWP occurs on 0.35 % of powertrain efficiency.For battery capacity value higher than 13 kWh the global reduction of the CO 2 emissions is not obvious. The method gives also an overview of the evolution of environmental categories indicators as a function of the cost of the vehicles. A direct relation links the economic and the environmental performances of the solutions. | [

https://doi.org/10.5278/ijsepm.6273 | Energy System Benefits of Combined Electricity and Thermal Storage Integrated with District Heating | In the development towards smart and renewable energy systems with increasing supply of electricity from fluctuating sources there is an increasing need for system flexibility. In this context the role and need for grid-level electricity storage is debated. Ideally, there would not be a need for storage, but the alternative system flexibility solutions may not cover all the flexibility needs, which will leave a potential for the storage of electricity. In this study, a compressed heat energy storage (CHEST) is assessed. It combines electricity and thermal storage in one system and can simultaneously benefit electricity and district heating (DH) systems. In a technical energy system analysis with the energy system of Germany as a case, a CHEST system is analyzed in different configurations with and without DH integration. The results indicate that electrochemical storage is more effective than CHEST if DH integration is not present. However, if DH integration is assumed, the CHEST technology can be more effective in reducing the primary energy supply. This applies, however, only for DH systems based on electrified heat sources, whereas in DH supplied by combined heat and power plants and fuel boilers, the CHEST system do not show more effective. | [

The pine needles can be used efficiently for electricity generation. In the present study, simulation research on a gridconnected biomass-based hybrid energy system was conceived to examine the feasibility in the western Himalayan territory. The locally available abundant pine needle was used as a biomass gasifier fuel with solar and wind resources. The Hybrid Optimization of Multiple Energy Resources software was used to model three distinct configurations of hybrid systems, Photovoltaic/Biomass gasifier/Grid (Case1), Photovoltaic/Biomass gasifier/Wind/Grid (Case 2), and only Grid (Case 3) for feeding electricity to selected educational building loads currently run by state grid. Lowest energy costs, total net present cost, and CO 2 emission were considered as parameters for electing feasible system configuration. The Photovoltaic/Biomass gasifier/Grid was found to be optimal hybrid energy system with the lowest cost of energy 0.102 $/kWh (29% and 7% lower than Case 2 and Case 3 respectively) and total net present cost $42081 at 83% renewable fraction without any power shortage. The biomass gasifier contributes most (61%) of the overall power output, led by PV (22%) and grid (17%) in the optimal configuration of the hybrid power system. The CO 2 emission analysis shows that the proposed system will save 27.8 Mt CO 2 /year (equated to the diesel-only system). The outcomes are found to be very pertinent to policymakers, hybrid system designers, and investors in the field of biomass-based hybrid renewable energy systems. | [

null | The effect of price regulation on the performances of industrial symbiosis: a case study on district heating | This study of the district heating system of Aalborg (Denmark) analyses how fiscal instruments affect the extent excess heat recovery helps reduce the carbon footprint of heat. It builds on a supply-and-demand framework and characterizes the changes in excess heat supply with consequential life cycle assessment in reference to one gigajoule distributed. The heat supply curve is defined through ten scenarios, which represent incremental shares of excess heat as the constraints of the said legal instruments are lifted. The heat demand curve follows the end-users' response to price changes. The most ambitious scenario doubles the amount of excess heat supplied and reduces the heat carbon footprint by 90% compared to current level, for an end-user price increase of 41%. The price increase results from a higher supply of excess heat at a higher price and an unchanged purchase cost from the coal-fired CHP plant despite a lower supply. This highlights the necessity of a flexible supplier when the share of recovered excess heat is high. | [

https://doi.org/10.54337/ijsepm.7116 | Energy system transformation for attainability of net zero emissions in Thailand | Thailand has a commitment to achieve net zero emissions. The roles of energy service demand reduction and hydrogen in the energy transition have not been sufficiently evaluated. This study analyzed energy and technological implications in the energy sector to attain net zero emissions in Thailand by 2050. This study used the AIM/Enduse model, a bottom-up type energy system model, as an analytical tool. A business-as-usual scenario and a net zero emission scenario are analyzed. Unlike other studies, this paper explored the energy transition in the absence of carbon, capture and sequestration (CCS) technology with a focus on energy service demand reduction and green hydrogen-based technologies. Decarbonization of the energy sector and transition towards net zero emission by 2050 in Thailand would require rapid deployment of renewable energy sources like solar, wind and biomass. In the net zero scenario, installed capacity of solar PV and wind for power generation in 2050 would reach 64 GW and 40 GW, respectively. In addition, green hydrogen will have a crucial role in achieving net zero emission target. The high carbon removals from LULUCF sector in Thailand will aid in reaching net zero emission without CCS technology in the energy sector. | [

The scenarios are modelled and analysed in the analysis tool EnergyPLAN and compared on primary energy supply and socioeconomic costs.

null | Comparison of driving cycles obtained by the Micro-trips, Markovchains and MWD-CP methods | Currently, there is an increasing interest for driving cycles (DCs) that truly represent the driving pattern of a given region aiming to evaluate the energy efficiency of electric vehicles and identify strategies of energy optimization. However, it has been observed increasing differences in the energy consumption reported using type-approval DCs and the observed in the vehicles under real conditions of use. This work compared the Micro-trips, Markov-chains and the MWD-CP methods in their ability of constructing DCs that represent local driving patterns. For this purpose, we used a database made of 138 time series of speed obtained monitoring during eight months a fleet of 15 transit buses operating on roads with different levels of service, traffic and road grades, under normal conditions of use. Then, we used 16 characteristic parameters, such as mean speed or positive kinetic energy, to describe the driving pattern of the buses' drivers monitored. Subsequently, we implemented three of the most widely used methods to construct DCs using this common database as input data. Finally, we evaluated the degree of representativeness of the local driving pattern contained in each of the obtained DCs. Toward that end, we defined that a DC represents a driving pattern when its characteristic parameters are equal to the characteristic parameters of the driving pattern. Therefore, we used as criteria of representativeness the relative differences between paired characteristic parameters and observed that the MWD-CP method produced the DC that best represents the driving pattern in the region where the buses were monitored, followed by the DC produced by the Micro-trips method. | [

Planners, researchers, regulators, operators and policy-makers need to ensure that the power system adapts to these changes. With change comes the unknown (issues and challenges) and unless a majority of these unknowns are identified, analysed and addressed properly, the system cannot achieve its maximum potential. The proper management, operation and integration of RES in the grid is one of the promising avenues for increasing the capacity of grid and thereby decreasing environmental impacts. This paper presents a review of the challenges and issues associated with RES integration in the power system and some of the existing techniques that are in use to address these. | [

null | Climate change perception, behaviour, and willingness to purchase alternative fuel vehicles: the missing dots | This paper explores the correlation between respondents concerns regarding climate change, their eagerness to adopt an AFV and their responsiveness to incentives. Seen as the solution for a cleaner mobility and greenhouse gas reduction in urban areas globally, alternative fuel vehicles (AFV) still own a modest market share in Europe. Among many reasons, the purchase price seems to be one of the most challenging to overcome. Incentives are considered a solution to mitigate the price barrier. The results of a survey carried out by the authors to 444 respondents led the authors to conclude that participants agree that AFVs contribute to tackle climate change. They also deduced that the vehicles price represents an offside for the lower-income households. Furthermore, the study revealed that the latter are less prone to buy an alternative fuel vehicle than higher-income families (59% against 80%). The authors also inferred that generally, households are more receptive to incentives or benefits based on up-front discounts or exemptions, directly impacting price and immediate savings, such as taxes exemption (value added tax and circulation tax), fuel discounts and purchase incentives. However, some differences were observed between income segments. For instance, the reduction or exemption of loan interests is among the most popular incentives for lower revenues, whilst higher revenues favour scrappage and non-financial incentives. Finally, in line with other studies, as upper incomes are less dependent on incentives and benefits to carry out the purchase, the authors put forward a differential and progressive approach for incentive instruments targeting lower revenues, allowing broader and equitable access to low carbon technology. | [

https://doi.org/10.54337/ijsepm.7474 | Bioenergy and Employment. A Regional Economic Impact Evaluation | There is a problem in estimating renewable energy's impact on regional economies of developing countries, owing both to the lack of disaggregated data on these renewable energy sources at the subnational level and a method to address its share in the energy matrix (in a context where oil and gas are yet hegemonic). We apply a method to solve both problems and to the case of Santa Fe province, Argentina, an important producer of biofuels (biodiesel from soybean and ethanol from maize). To disaggregate the biofuel sector, we combine aggregated sector information with subsector surveys. Once the share of biofuels is established in the economy and their potential to create jobs, it is possible to generate statistics on the input-output relationships. With the latter, we estimate a hybrid input-output model and calculate the effects of shocks (defined as policies as well as the effect of exogenous elements impacting the performance of the sector) on production and employment stemming from the full utilization of existing idle capacity, as well as from new investments in the sector. The results, allow us to policy evaluations, for instance, the consequences of acceleration of the energy matrix transition to renewables through regulations, to study the effect of changes in relative prices of energy, determine the effect on potential employment creation of subsidies to promote the activity, etc. The sector we analyze empirically had an important idle capacity plus delayed investment projects because of external shocks. In the event of overcoming transient problems to export biofuels (and to attain full capacity utilization of current infrastructure), from expanding supply with new investments, the employment effect is proportionally much larger since transient jobs would be created in the construction phase. | [

https://doi.org/10.5278/ijsepm.2016.9.5 | Optimal Phasing of District Heating Network Investments Using Multi-stage Stochastic Programming | Most design optimisation studies for district heating systems have focused on the optimal sizing of network assets and on the location of production units. However, the strategic value of the flexibility in phasing of the inherently modular heat networks, which is an important aspect in many feasibility studies for district heating schemes in the UK, is almost always overlooked in the scientific literature. This paper considers the sequential problem faced by a decision-maker in the phasing of long-term investments into district heating networks and their expansions. The problem is formulated as a multi-stage stochastic programme to determine the annual capital expenditure that maximises the expected net present value of the project. The optimisation approach is illustrated by applying it to the hypothetical case of the UK's Marston Vale eco town. It was found that the approach is capable of simulating the optimal growth of a network, from both a single heat source or separate islands of growth, as well as the optimal marginal expansion of an existing district heating network. The proposed approach can be used by decision makers as a framework to determine both the optimal phasing and extension of district heating networks and can be adapted simply to various, more complex real-life situations by introducing additional constraints and parameters. The versatility of the base formulation also makes it a powerful approach regardless of the size of the network and also potentially applicable to cooling networks. | [

The classes are relative to the particular temperature distribution and for the particular night of the survey. Classification assigns every pixel into one of five classes based on where the pixel falls in the histogram, into an integer between 1 and 5, with 1 representing being the "coolest" pixels and 5 being the "hottest" resolution, based on a case study acquired over Newcastle upon Tyne (United Kingdom). The ultimate aim is combine this information with building level data set for Newcastle and adds on the energy modelling aspect through linking with the English House Survey (EHS) as input to the Cambridge Housing Model (CHM). This provides the means to produce building level energy use estimates and surface temperature, which in turn can be analysed both spatially and aspatially. This building level approach provides the potential for energy planners and other bodies to model energy interventions measures with flexibility in scale and to potentially adapt plans to the spatial variability of the local area characteristics. | [

https://doi.org/10.5278/ijsepm.3490 | Planning of district heating regions in Estonia | It is quite evident that district heating (DH) networks will continue to be developed in order to complete their transition towards the 4th generation district heating by decreasing heat losses, increasing the share of renewable and waste heat sources, and integrating energy storage units and smart operating solutions. The significance of district heating in Estonia is very high, and developing this sector is very important for achieving climate and energy targets set by Estonia. Consumers play important role in the transition process, and for the purpose of informing and educating consumers, a district heating promo app has been implemented at the national level. One of the app's modules shows consumers the energy mix that will be required to supply heat via district heating in the future, with all of the planned changes and different district heating regions taken into account. Measures and goals proposed in the Estonian National Development Plan of the Energy Sector until 2030, as well as all available heating strategies from various district heating regions have also been considered. The algorithm of the methodology takes into account possible changes in heating demand caused by increased energy efficiency of the building sector, heat loss reduction due to renovation of existing DH networks and possible reduction of DH temperature, as well as increase in the share of renewable energy sources and its impact on primary energy consumption and CO 2 emissions in DH area. Scenarios show which fuel/primary energy mix is expected to be used for heat generation in the future (the data is given for each district heating region), as well as the amount of CO 2 emissions. Several typical case studies are also provided. | [

https://doi.org/10.5278/ijsepm.2018.15.4 | The price of wind power generation in Iberia and the merit-order effect | Renewable energy generation depresses electricity spot prices, which is often used as argument to justify incentives provided to renewables. In the so-called "merit-order effect", renewable power reduces the load available for conventional power and displaces higher marginal cost generation out of the market. In this study, we estimate the value of the "merit-order effect" due to wind power generation in the Iberian market, in the period between 1 st January 2008 and 31 st October 2016. This value, representing consumers' potential cost savings, is compared with the direct costs of the financial incentives in Portugal and in Spain. The accumulated "merit-order effect" amount is estimated to be 26.1 billion €, whilst the total values for the financial incentives reported is 23.9 billion €. The value of the "merit-order effect" explains the existing lower returns by conventional generation and might have additional impacts on future RES projects, subject to normal electricity market risks. | [

https://doi.org/10.5278/ijsepm.3335 | Experimental demonstration of a smart homes network in Rome | According to the European Strategy Energy Technology (SET) Plan, the resident-user engagement into the national energy strategy is pivotal to the project as it is considered to be one of the most important challenges. The Italian Minister of Economic Development and ENEA has entered into a Programme Agreement for the execution of the research and development lines of General Interest for the National Electricity System. In particular, as part of the "Development of an integrated model of the Urban Smart District" a Smart Home network experimentation has been carried out in Centocelle, in the south-eastern outskirt of Rome. This project aims to develop a replicable model able to monitor energy consumption, indoor comfort degree and safety in residential buildings. Then raw data are transmitted to a higher level ICT platform where they are analysed and aggregated to provide the user and the community with a series of constructive and valuable feedback. All this information can shed light on the user's behaviour patterns and what ought to be improved to increase their energy awareness. The heart of the system is the Energy Box (EB) that allows to control all the devices (sensors and actuators) and to transform each and every home into an active node of a smart network. It lets the user share data and information with the outside world as well as to increase residents' sense of involvement and belonging to the community, providing them with new forms of interaction. In perspective, the system architecture aims to transform each user from a mere consumer into an active participant in the energy market, able to control demand (demand-side management). Finally, the brand-new home digital infrastructure is paving the way to a series of additional services, such as assisted living and home security. | [

null | Securing future water supply for Iran through 100% renewable energy powered desalination | Iran is the 17 th most populated country in the world with several regions facing high or extremely high water stress. It is estimated that half the population live in regions with 30% of Iran's freshwater resources. The combination of climate change, increasing water demand and mismanagement of water resources is forecasted to worsen the situation. This paper shows how the future water demand of Iran can be secured through seawater reverse osmosis (SWRO) desalination plants powered by 100% renewable energy systems (RES), at a cost level competitive with that of current SWRO plants powered by fossil plants in Iran. The optimal hybrid RES for Iran is found to be a combination of solar photovoltaics (PV) fixed-tilted, PV single-axis tracking, Wind, Battery and Power-to-Gas (PtG) plants. The levelised cost of water (LCOW) is found to lie between 1.0 €/m 3 and 3.5 €/m 3 , depending on renewable resource availability and water transportation costs. | [

https://doi.org/10.54337/ijsepm.7478 | review of social dynamics in complex energy systems models | The problem of techno-economic approaches to evaluating energy transition pathways has been constantly reported in the literature, while existing research recognises the critical role played by social aspects in energy systems models. System dynamics (SD) has been pointed out among modelling techniques as a suitable tool to evaluate the interdisciplinary nature of energy transitions. This paper explores how energy system-related SD models have incorporated social aspects through a literature review. Models were assessed based on their geographical resolution, time horizon, methodological approach, and main themes: supply-demand, energy-economyenvironment (3E), energy-transport, water-energy-food (WEF) nexus, and consumer-centric and socio-political dynamics. Social aspects considered include behaviour and lifestyle changes, social acceptance, willingness to participate, socio-economic measures, among others. As expected, the representation of social aspects was not standard among the papers analysed. Socioeconomic aspects were most commonly included in supply-demand and 3E models. Energytransport and WEF models mainly incorporated changes in travel and consumption habits, respectively. The last theme had a more diverse approach to social aspects that deserves further attention, especially for energy access and justice issues. Other research lines include modelling approaches combination, enhanced participatory and transparent processes during model development, and use of SD models in policy-aiding and stakeholders' information processes. | [

https://doi.org/10.5278/ijsepm.2016.10.1 | Smart Energy Systems and 4th Generation District Heating | Energy systems are becoming increasingly complex, integrating across traditionally separate sectors such as transportation, heating, cooling and electricity. Integration through the use of district heating is the main topic of this editorial introducing volume 10 of the International Journal of Sustainable Energy Planning and Management. The editorial and the volume presents work on district heating system scenarios in Austria, grid optimisation using genetic algorithms and finally design of energy scenarios for the Italian Alpine town Bressanone-Brixen from a smart energy approach. | [

null | A biomass waste evaluation for power energy generation in Mexico based on a SWOT & Fuzzy-logic analysis | Power energy generation in Mexico based on bioenergy is currently insignificant. However, the potential for taking advantage of biomass resources in the country is considerable. This article aims to evaluate the use of biomass waste for the Mexican energy transition in the near future. The methodology starts by identifying sites with biomass waste and establishing the conversion processes needed to produce electricity for each type of biomass. A SWOT analysis was implemented to define the criteria for evaluating all options on the same basis. The opinion of experts in energy systems was collected to assign priority to each criterion. A fuzzy-logic inference system was formulated to assess the options based on the quality of their attributes. The output obtained from the fuzzy analysis is a sustainability prioritisation of all options. We analysed a case study for the Baja California Sur (BCS) region, and the results show the prioritisation ranking of 24 alternatives regarding the sustainable use of bioenergy in the region and we made a proposal of an indicative plan to introduce bioenergy in the region from now until 2032. If the indicative plan were implemented, 61% of the power demand of BCS could be covered with bioenergy by 2032. | [

null | Energy Transition in the global South – Editorial for the International Journal of Sustainable Energy Planning and Management Vol 35 | This 35 th volume of the International Journal of Sustainable Energy Planning and Management includes work investigating different biomass resource utilisation scenarios for Mexico as well as scenarios for the transition of Thailand. The latter finds significant photo voltaic requirements when factoring in the transition to green hydrogen for transportation. Transportation is also the focal point in a study of Indonesia, finding that cost and emission optimisation are pushing optimum in different directions. Continuing with Indonesia, the country is seeing a rapidly growing electricity demand, and Siregar investigates social, environmental, technical, and economic criteria for the development of the system towards a more sustainable electricity supply. The scenario analyses are largely based on larger societal transitions, but Appiah makes a more concerted effort to investigate the actual investments in renewable energy sources. Lastly, an article focuses on the industrial sector and how energy efficiency may be affected by policies. | [
