Nowadays, in the context of climate change, efficient energy management and increasing the share of renewable energy sources in the energy mix are helping to reduce greenhouse gases. In this research, we present the energy system and its management and the possibilities of its development through the example of an ecovillage. The basic goal of such a community is to be economically, socially, and ecologically sustainable, so the study of energy system of an ecovillage is especially justified. As the goal of this community is sustainability, potential technological and efficiency barriers to the use of renewable energy sources will also become visible. Our sample area is Visnyeszéplak ecovillage, where we examined the energy production and consumption habits and possibilities of the community with the help of interviews, literature, and map databases. By examining the spatial structure of the settlement, we examined the spatial structure of energy management. We formulated development proposals that can make the community’s energy management system more efficient.

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.

Decentralized Energy

Until recently, the prevailing idea was that for the functioning of the energy system it is necessary to be composed of large plants and for energy to move from the centre of production to cities and places of consumption. With the advent of decentralized energy production systems and new technologies for their use, the original model is changing more and more. EU Directive 2018/2001 on the promotion of the use of renewable energy sources (RES) designates “prosumers”, i.e. at the same time both producers and consumers of renewable energy, as well as RES communities, while EU Directive 2019/944 introduced the term “citizen energy communities”, i.e. civil energy communities, provided that this Directive, in addition to the distributive production of electricity from RES, also includes electricity from other sources. EU member states are obliged to adopt their own regulations regarding the implementation of the directives, and after that the appropriate incentive measures. The Energy Communities initiative offers citizens new opportunities in terms of active involvement in energy issues. As they are decentralized RES-based projects, they promote the practice of sustainable energy production and consumption, as well as energy storage and exchange within the community. Traditionally passive consumer becomes an energy “prosumer”, a co-owner of a RES plant and a member of the energy community. There are thousands of so-called RES cooperatives in Europe, which are the most common organizational form of energy communities and can play an important role in the process of decentralization of the energy system. The transition to decentralized energy production has many advantages, namely: the use of local energy sources, increased security of local energy supply, shorter transport distances and reduced losses in energy transmission, encouraging community development and creating local jobs. The purpose of this paper is to bring closer to the general public in Serbia the concept of energy communities, what they are and what their role is, with most of the work dealing with energy communities in the EU.

At present, the energy from renewable sources is an important element of the sustainable development strategy of the European Union (strategy covering the period until 2020). The article presents the role of renewable energy in the structure of primary energy sources and total energy production. In order to evaluate the present-day role of the renewable energy sector, specific European Union states were analysed, with particular focus on Poland, the country whose results were juxtaposed with the average ratios established for the EU-28. A detailed analysis of the current facts was performed (also a forecast for the period running up to 2020 was made), where particular energy sources were distinguished in the renewable energy production structure. A special role among renewable energy sources was ascribed to solar energy, wind energy, hydropower, geothermal energy, biogases and biofuels. The conclusions drawn from the research point out to the fact that the development of renewable energy in Poland is growing slowly but surely. In 2011, the share was at 9.5% and by 2015 it grew to 11.8%, with the target set for 2020 being at the level of 15.0%. The production of energy from renewable sources is improving (from 7.5 to 8.1 Mtoe). Nevertheless, the share of primary energy obtained from renewable energy sources in the total primary energy is less than half of the EU share. The data showcase that the projected aim is likely to be achieved; however, the few years to come should envisage some intensification of activities oriented to this goal. Biomass now enjoys the dominant role but its significance is gradually waning, which favours wind energy and biofuels. The projected directions of renewable energy development indicate that this sector is going to be a significant factor in implementing the sustainable development policy in the years to come.

The European Union (EU) countries, as one of the most economically developed regions in the world, are taking increasingly decisive actions to reduce the emission of harmful substances into the natural environment. This can be exemplified by a new climate strategy referred to as “The European Green Deal”. Its basic assumption is that the EU countries will have achieved climate neutrality by 2050. To do so, it is necessary to make an energy transition involving the widest possible use of renewable energy sources (RES) for energy production. However, activities in this area should be preceded by analyses due to the large diversity of the EU countries in terms of economic development, the number of inhabitants and their wealth as well as geographical location and area. The results of such analyses should support the implementation of adopted strategies. In order to assess the current state of the energy sector in the EU and indicate future directions of activities, research was carried out to analyze the structure and volume of energy production from RES in the EU countries. The aim of the study was to divide the EU countries into similar groups by the structure and volume of energy production from RES. This production was compared with the number of inhabitants of each EU country, its area and the value of Gross Domestic Product (GDP). This approach allows a new and broader view of the structure of energy production from RES and creates an opportunity to take into account additional factors when developing and implementing new climate strategies. The k-means algorithm was used for the analysis. The presented analyses and obtained results constitute a new approach to studying the diversified energy market in the EU. The results should be used for the development of a common energy and climate policy and economic integration of the EU countries.

Renewable energy production needs serious attention in highly traditional, inefficient, and energy-dependent countries like Nepal. Moreover, the option of an effective renewable energy technology that is economically feasible and environmentally acceptable is a topic of interest due to the availability of various types of renewable energy sources in Nepal. Among other renewable energy sources like micro hydro, solar, biogas etc, very few studies had been conducted on wind energy sources in Nepal and those few studies also focuses mostly on large scale wind farming. So, this study analyzes the suitability of distributed wind energy production in Tila village of Jumla district in the western part of Nepal. Five-year (2015-2019) wind speed data were examined to obtain wind power density and energy density. Two-parameter Weibull probability density function was used to evaluate these two quantities. The annual Weibull parameters k and c of 1.73 and 4.21 m/s were obtained to calculate 43.79 W/m2 power density and 378.37 kWh/m2 energy density. This study also provides the economic evaluation of a 100 kW distributed wind energy system, and the technical and economic aspects of the proposed system are compared with the corresponding characteristics of the existing renewable energy systems, i.e., micro hydropower and solar power. The study shows that when there is not enough sunlight for the solar PV system and not enough water flow coupled with maintenance problems in the micro hydropower system, the distributed wind energy system may function as a substitute system.

The industry attention to the environment has been reducing lately, leading to irreversible climate change, reaching the limit of mining, and critical indicators of СО2 emissions. That is why the EU has launched a new Green Policy which includes strategic directions for energy efficiency and which is expected to restore biodiversity and slow down the pace of climate change. Thus, on December 11, 2019, there was held the presentation of the “European Green Course”, the main targets of which are to increase the level of energy saving by creating closed cycles in the economy; to minimize greenhouse gas emissions by 2050; to form biodiversity and climate neutrality. Accordingly, countries that accept the terms of the green deal policy need to review all aspects of their economy, from energy production to food consumption, from industry to transport and construction. The purpose of the article is to analyse publications in order to identify public’s awareness of radical changes in economic and ecological spheres. The article provides a bibliometric analysis of research in the field of green deal policy, energy conservation and energy efficiency through the introduction of renewable energy sources. The authors selected 337 papers which were published in 1999-2019. Scopus provided the database for analysis. By means of VOSviewer the results of bibliometric analyses were visualized in a definitions map. It allowed identifying six clusters that combine 131 terms. As a result of the research, the connection between the terms – renewable energy sources and energy saving – was revealed with the help of the constructed bibliographic map.
