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.

Renewable Energy Development

Due to the exhaustion of the fossile fuel reserves of the Earth, the increase of fossile fuel prices and the difficulties concerning stable fuel supply, the increase of electricity production from renewable energy sources has a special strategic importance. In this study, I am going to evaluate the circumstances of the production and use of renewable energy sources in Hungary and in the European Union. I present the Hungarian economic, energy policy-related and social circumstances which make it necessary to support renewable energy production. I am going to give an overview on the related EU strategies concerning the sector and the Hungarian development plan in this field. I pay particular attention to the examination of development opportunities and the R&D activities going on in this area in Hungary, as well as the efficiency of the means used to improve renewable energy use.

The purpose of this article is to present the changes in the structure of production and consumption of energy from renewable energy sources in Poland and in the European Union. Renewable energy sources account for only about 16% of world energy production. This situation, however, from year to year changes. Prym in the use of energy from renewable sources leads the European Union, which has set itself an ambitious target that by 2020, 20% of the energy extracted from the green renewable energy sources.

AbstractAs Poland is considered a coal country, renewable energy resources still do not have a significant share in energy production. Further, 14% contribution of renewable energy to total primary energy production in 2020 is endangered. Thus, in order to speed up with renewable energy sources new actions should be stimulated. The aim of the article is to describe the most popular renewable energy installations in Poland and further to search for a case study indicating that an investment in renewable sources is profitable without financial support. The results indicate that prior literature does not present any analysis of profitable renewable energy investment without financial support. It states the need for regulators to implement additional financial support not only on the European Union level but also on the national one.

The article is aimed at modeling the energy market of Ukraine on the meso-level, identifying its features and development problems, forming a system of indicators for monitoring the development of electricity production at the regional level. It is determined that Ukraine produces electrical power mainly from non-renewable energy sources, namely fossil and mineral fuels, using nuclear power plants and thermal power plants, which comprises 54% of the total electricity production. Wind, solar sources of electrical power, biofuels and hydroelectric power plants make up a smaller part of production – 7%. It is noted that Ukraine annually consumes about 92 million tonnes of oil equivalent (toe) of energy, has a high level of energy intensity of the economy, therefore, in order to reach the world average level, it is necessary to reduce energy consumption by 50 million toe. The level of losses of the produced and imported energy during its transformation and transportation to the end user is 44%. The potential for reducing energy consumption during consumption in sectors such as housing, budget-based and energy supply is about 19 million toe. To assess the state of the energy sector in Ukraine in 2019, a grouping of regions of Ukraine was carried out using cluster analysis. The regions that have entered the 1st cluster, namely: Dnipropetrovsk, Donetsk and Zaporizhzhia regions, have the best prospects for the rapid innovative development of the energy market. The regions that are included in the 3rd cluster have the lowest values of energy sector development indicators among other clusters and require special attention to the development of new, cost-effective energy technologies. The system of indicators for the analysis of the energy market development on meso-level is substantiated. The proposed indicators are adapted to the indicators of monitoring the achievement of sustainable development goals, namely: sustainable development goals 7 «Ensuring access to inexpensive, reliable, sustainable and modern energy sources for everyone».

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 World

The energy sector holds a crucial strategic importance for development and its sustainability. However, the energy reserves in Turkey are insufficient for the increasing energy demand. For this reason, the need for alternative energy sources has emerged. The fact that fossil fuels used in energy production will be exhausted and their damaging effects on the environment has made it inevitable for the world to use renewable energy. In Turkey, the following are the main energy sources used in electricity production: hydraulic sources, brown coal, natural gas, coal and fuel oil. The use of renewable energy sources in electricity production has shown a considerable development in the world over the past few decades. However, these energy resources have yet to be exploited to any large extent in Turkey. In this chapter, the range of potential renewable energy resources available for electricity production in Turkey will be analyzed in order to determine the necessary technical substructure to make these renewable energy resources more attractive.
