The current paper analyzes the awareness of renewable energy sources (RES), the relationship between self-reported and actual knowledge, and the correlation among the knowledge of renewable energy sources, the characteristic stereotypes, and the typical attitude of different social groups to energy, comparing them with international experience. A nationwide representative questionnaire-based survey was carried out involving 1002 people in Hungary in 2019. Better education, a higher income, an active white-collar profession, and a health- and environment-conscious approach to life (LOHAS (lifestyle of health and sustainability) segment) are definitely an advantage when it comes to knowledge of renewable energy sources. No significant relationship was detected in terms of age; however, in cluster formation, young people were typically found to be better informed. Overall, the actual knowledge of the Hungarian respondents is more favorable than the self-reported one, and the basic level of knowledge of energy sources in the case of wind and hydropower exceeds international experience. The social factors of better knowledge essentially correspond to the international trends; however, regarding firewood, solar, and wind energy, the average Hungarian has certain false stereotypes that can be considered typical. The assessment of convenience and that of environmental aspects are almost the same.

The article aims to study current trends in the use of solar energy in Ukraine and the world as one of the main directions of decarbonization of the national economy. The authors systematize the prospects, advantages and disadvantages of the development of renewable energy sources. They conducted a comparative analysis of the "efficiency" of solar energy in some countries and Ukraine. The authors determined that the leading position in terms of the share of energy consumed from renewable sources is occupied by countries with developed economies due to the availability of effective motivational mechanisms. From the experience of EU countries, the authors concluded that renewable energy sources form a prerequisite for obtaining additional socio-economic and environmental effects. In the presence of favorable market conditions, renewable energy sources can increase the level of energy security in the country and its energy independence. The article analyzes the legislation of Ukraine on stimulating the development of alternative energy. The authors proposed two opposed ways of further developing solar energy in Ukraine. In particular, the country can implement methods of using alternative energy, which developed countries have successfully implemented. Another area involves increasing research and innovation in implementing, using, maintaining, and utilizing energy-generating devices from alternative energy sources. Despite the polarity of the proposed directions for further development of renewable energy, in both cases, the state policy on attracting investment and promoting the use of energy from alternative energy sources is crucial. In addition, the authors noted the benefits for society from the development and implementation of alternative energy sources.

Abstract When talking about the future of Europe we also think about alternative energy sources. It is up to national governments to decide how to encourage investments in this field in order to contribute to the 20-20-20 EU-objective. Until the network delivery cost for electricity produced from renewable sources will be comparable to the cost for energy from traditional sources ("grid parity"), the development of businesses and markets for electricity from renewable sources is going to be driven by support schemes. The state of the grids and the facility of grid-access constitute another two key factors influencing the development of this sector. Last but not least, the question of policy consistency is raised within the business community. Over the past years some support schemes have proved to be more effective than others, and grid conditions have also evolved. Policies supporting the development of renewables also changed at EU-level and at national levels. Based on statistics, scientific literature and the feedback of the business community, this study aims to analyse the development of renewable energy sectors in the European Union by comparing Germany’s and Romania’s experience. Also this study describes the current and expected future market situation in these countries relying on data gained from questionnaires and interviews with specialists in the renewable field.

In the recent attempts to stimulate alternative energy sources for heating and cooling of buildings, emphasise has been put on utilisation of the ambient energy from ground source heat pump systems (GSHPs) and other renewable energy sources. Exploitation of renewable energy sources and particularly ground heat in buildings can significantly contribute towards reducing dependency on fossil fuels. The study was carried out at the Energy Research Institute (ERI), between September 2016 and November 2017. This paper highlights the potential energy saving that could be achieved through use of ground energy source. The main concept of this technology is that it uses the lower temperature of the ground (approximately <32°C), which remains relatively stable throughout the year, to provide space heating, cooling and domestic hot water inside the building area. The purpose of this study, however, is to examine the means of reducing of energy consumption in buildings, identifying GSHPs as an environmental friendly technology able to provide efficient utilisation of energy in the buildings sector, promoting the use of GSHPs applications as an optimum means of heating and cooling, and presenting typical applications and recent advances of the DX GSHPs. It is concluded that the direct expansion of GSHP are extendable to more comprehensive applications combined with the ground heat exchanger in foundation piles and the seasonal thermal energy storage from solar thermal collectors. This study highlights the energy problem and the possible saving that can be achieved through the use of the GSHP systems. This article discusses the principle of the ground source energy, varieties of GSHPs, and various developments.

Ukraine has untapped potential for the production of own energy from renewable sources - processing of livestock waste (animal manure and bird droppings) with the formation of biogas, which can then be used to produce electricity, heat or fuel - analogues of natural gas (methane) (in particular, for own needs of farms). Currently in Ukraine, the generation of large amounts of waste on industrial farms is an environmental problem that needs to be addressed. Recycling livestock waste to generate biogas will partially solve environmental problems, as well as benefit from decentralized renewable energy production or fuel production. The role of renewable energy sources in energy production is constantly growing and now the issue of increasing the share of renewable sources in the energy balance of each country is relevant. In the supply of primary energy, the share of renewable energy accounts for 13% worldwide. Of these, biomass accounts for 10%, or 258 million tons per year, ie in the world biomass provides the largest share of energy supply from renewable sources. Domestic agricultural enterprises are significant consumers of fuel and energy resources, so they face the objective need to use alternative energy sources, including biofuels and the introduction of innovative energy-saving technologies. Biogas production is an efficient and attractive investment technology, due to the presence of significant raw material potential, favorable climatic and other. However, the level of introduction of this type of energy in the agro-industrial complex is insufficient, which is due to a number of issues, including insufficient level of practical recommendations for choosing power generators, their number, modes of operation taking into account daily energy consumption schedule, load and optimal efficiency. installations while providing autonomous power supply of the enterprise. This paper determines the level of energy supply of livestock farms through the use of biogas plants as a source of energy used for livestock waste.
