The paper presents results of scenario modelling and assessment of energy transition to 2050 in the Zhytomyr territorial community (TC), which provides for a switching from fossil carbon based energy resources in the current TC energy system functioning to 100% use of renewable energy sources (RES) which meets all energy demands and supports the Sustainable Development of TC in accordance with the relevant UN goals. For this purpose, the optimizational economic and mathematical TIMES-Zhytomyr model (no analogues in Ukraine), based on the TIMES-Ukraine model, was developed. It includes 647 energy technologies that are currently available or may be presented in the coming years in Ukrainian market. For the development of the TIMES-Zhytomyr model, a low-available local energy statistics was processed. As a result, the first energy balance by the form of the International Energy Agency for the large Ukrainian city and the basic energy-technological system of Zhytomyr TC were developed. Using the TIMES-Zhytomyr model, based on foreign and Ukrainian experience, for the first time, four scenarios of Zhytomyr TC energy system development were designed and modelled, covering all economic sectors and household sector (population). The first one is the Baseline scenario, which displays the possible dynamics of the energy system development without a purposeful energy efficiency policy, the development of RES, etc. Three other scenarios are aimed at studying TC’s transition capabilities by 2050 to 100% renewable energy and environmentally friendly technologies use. The results of modelling confirmed that the available renewable energy resource and technological potential allows Zhytomyr TC to perform the energy transition to 2050 in an economically feasible and socially acceptable way, significantly reducing energy and carbon intensity of the local economy, substantially eliminating GHG emissions, increasing the welfare of citizens and creating at least 10 thousand new workplaces. It will also significantly contribute to Zhytomyr TC to reach at least 10 of the 17 UN Sustainable Development Goals. The research results presented, due to a significant novelty and large-scale relevance of the task, are essential in both the theoretical and practical significance. They can be used by scientists for their research and by authorities and experts for development of local, regional or national level strategies, plans or programs of economic, energy, transport, climate and ecology scope. It can also be considered as one of the first steps in preparation of a comprehensive strategy for the Zhytomyr TC development to achieve climate neutrality in accordance with the current objectives of the European Union.

Abstract Examining willingness-to-pay (WTP) for renewable energy sources (RES) as well as views on energy topics can enable policymakers to design effective measures for facilitating the transition from fossil fuels to a renewable-based energy system. The aim of this study was to investigate environmental students’ willingness-to-pay for renewables and their views on various energy topics. Results showed that respondents preferred renewable-based electricity production to conventional energy production while solar energy emerged as the most preferred renewable type. In addition, most respondents were willing to pay for renewable energy but would pay relatively low sums of money per month. Moreover, respondents were divided over whether new lignite plants should be constructed in Greece. Finally, social media and special websites were the most favored media of daily information.

The aim of the work is to analyze possible ways of decarbonization of the EU heat supply sector. The task of the work is to identify the most promising areas and develop appropriate recommendations for Ukraine. The heat supply sector of the EU and Ukraine needs decarbonization, for which there is a big potential and different areas of implementation of relevant measures. In Europe, such a strategy is set out in the Roadmap for decarbonization of the EU heating sector until 2050, the main provisions of which are in line with objectives of the European Green Deal and the EU Strategy on Heating and Cooling. European experts have developed the concept of a smart energy system, which was taken into account when preparing the Roadmap for decarbonization of the EU heating sector until 2050. A number of carried out studies have shown that a smart energy system with 50% district heating integrated with other parts of the overall energy system is more efficient than a conventional energy system or the one based on decentralized heat supply, in terms of the possibility of using a high share of renewable energy. It is recommended for Ukraine to finalize the Concept of green energy transition until 2050, taking into account European approaches to the development of heating systems and the use of modern biofuels. It is also recommended to expand the current Concept of heat supply of Ukraine to the level of a strategy with an emphasis on the development of district heating systems, wide involvement of renewable energy sources and new technologies.

The Impact

Climate change is an unprecedented challenge in human history. It requires further immediate and concerted action. Understanding the stage of development of each energy resource, as the impact on the energy system to make informed decisions and prescribe a healthy energy future has thus become a priority. Decisions such as the phasing out of fossil fuels and the transition to an efficient and 100% renewable energy system, as well as increasing the storage capacity of greenhouse gases using environmentally sustainable approaches, maintaining natural ecosystems that generate environmental services, and restoring the degraded ones are now a top issue. Therefore, the relationship between energy and environmental policy is becoming essential. Accordingly, this paper will focus on the transition to renewable energy, the adaptation to climate change and the energy transition at EU level being strenuously debated, in order to build a holistic context of the actual situation. Adaptation to climate change requests a complex scientific study, given the diversity of uncertainties involved, and the interconnections between different areas, such as agriculture, sustainable development or energy industry. Therefore, the aim of research is to provide holistic understanding of the current climate issues, according to the mentioned fields. In this context, it is emphasized the benefits of clean energy by investigating the methods for achieving a prolific energy transition, from a conventional to a sustainable one. Carefully analysing the commitments and the transition to a low-carbon electricity system looking behind the causes and studying closely the underlying elements of all these topics, using the qualitative research method as a basis to indulge in further analysis and research, it was outlined a detailed analysis of the current climate context. In conclusion, the effect of the pressure brought into play by human exploitation of goods and services on the ecosystems was associated with the ongoing concerns of environmental degradation, climatic variations, natural and ecological distortions, and financial setbacks. Taking into account the drive toward accomplishing sustainable development and environmental quality, powerful policies are being implemented, but given the variety of investment conditions in each country and including the different characteristics of the financial markets, there is no unique solution that works for everybody. Therefore, the transition to a more sustainable energy system has a verity of implications but it is an essential condition for sustainable development.

The energy transition from fossil-based energy sources to renewable energy sources of an industrialized country is a big challenge and needs major systemic changes to the energy supply. Such changes require a holistic view of the energy system, which includes both renewable potentials and consumption. Thereby exergy, which describes the quality of energy, must also be considered. In this work, the determination and analysis of such a holistic view of a country are presented, using Austria as an example. The methodology enables the calculation of the spatially resolved current exergy consumption, the spatially resolved current useful exergy demand and the spatially resolved technical potential of renewable energy sources (RES). Top-down and bottom-up approaches are combined in order to increase accuracy. We found that, currently, Austria cannot self-supply with exergy using only RES. Therefore, Austria should increase the efficiency of its energy system, since the overall exergy efficiency is only at 34%. The spatially resolved analysis shows that in Austria the exergy potential of RES is rather evenly distributed. In contrast, the exergy consumption is concentrated in urban and industrial areas. Therefore, the future energy infrastructure must compensate for these spatial discrepancies.

Negative Effects

The economic impacts of the German Renewable Energy Act (EEG) are of considerable importance for the discussion of the energy transition in Germany (Energiewende). The Energiewende implies structural changes of the energy system by deploying Renewable Energy (and energy efficiency) Technologies (RET), but it also may induce structural changes for the overall economy, with uneven effects on a sub-national level. North-Rhine Westphalia (NRW) is an ideal case to study such regional disparities, since this federal state has scarce per-capita renewable energy sources, whereas it stands out for its energy intensive industry and fossil-fuel based power plants. In order to support renewable energy policies, mostly gross impact assessments of RET deployment have been carried out both on national and regional levels. By definition, such analyses result in positive assessments, since only expansionary effects resulting from additional demand for RET are accounted for. This paper, in contrast, presents a net impact assessment of the EEG on the NRW economy of both expansionary and contractionary effects. The latter consist of negative income effects, increased production costs and, the crowding-out of conventional energy due to the renewable energy financing mechanism (i.e., electricity surcharge), as well as its preferential status for feed-in. Our findings show how North-Rhine Westphalia, with regard to the operation of RET, suffers disproportionally from negative effects in relation to the value addition of its economy in comparison to the rest the country, whereas it benefits marginally from the production of such facilities.

Hybrid Renewable Energy

After the Great East Japan Earthquake, energy security and vulnerability have become critical issues facing the Japanese energy system. The integration of renewable energy sources to meet specific regional energy demand is a promising scenario to overcome these challenges. To this aim, this paper proposes a novel hydrogen-based hybrid renewable energy system (HRES), in which hydrogen fuel can be produced using both the methods of solar electrolysis and supercritical water gasification (SCWG) of biomass feedstock. The produced hydrogen is considered to function as an energy storage medium by storing renewable energy until the fuel cell converts it to electricity. The proposed HRES is used to meet the electricity demand load requirements for a typical household in a selected residential area located in Shinchi-machi in Fukuoka prefecture, Japan. The techno-economic assessment of deploying the proposed systems was conducted, using an integrated simulation-optimization modeling framework, considering two scenarios: (1) minimization of the total cost of the system in an off-grid mode and (2) maximization of the total profit obtained from using renewable electricity and selling surplus solar electricity to the grid, considering the feed-in-tariff (FiT) scheme in a grid-tied mode. As indicated by the model results, the proposed HRES can generate about 47.3 MWh of electricity in all scenarios, which is needed to meet the external load requirement in the selected study area. The levelized cost of energy (LCOE) of the system in scenarios 1 and 2 was estimated at 55.92 JPY/kWh and 56.47 JPY/kWh, respectively.
