Given Ukraine's high dependence on imported energy, primarily natural gas, and the availability of great biomass potential, it has been proven that bioenergy is one of the strategic directions of the sector's development in renewable energy sources. It is determined that the pace of bioenergy development in Ukraine still lags significantly behind European ones. It is established, that in the developed countries of the world use of biomass as a source of energy continues to play an important role because of a significant increase in prices for oil and gas, as well as the growing demand for protection of the environment. Therefore, the introduction of modern technologies for continuous energy production from biomass is an important condition for the solution of problems of supply of energy and prevent degradation of the environment. The possibility of using biofuels in the Kyiv region is proved, the investment attractiveness of this region as a source of thermal energy is revealed. The methodical approach to estimating the theoretical potential of waste due to the use of alternative energy sources is substantiated. The theoretical energy potential of the biomass of by-products of agricultural crops of private enterprise "Sosnova" was assessed, which made it possible to determine the prospects of an agricultural enterprise in the energy supply of the Kyiv region at the expense of biofuels. According to the generally accepted method, the theoretical energy potential of straw and vegetable waste of private enterprise "Sosnova" was calculated, which in the market turnover in 2019 amounted to 8392 tons of oil equivalent. It was determined that the predominant type of biomass in the studied enterprise were corn stalks and wheat straw. On the example of the object of the school, which is located near the investigated enterprise, the calculation of savings on heating by replacing the traditional type of fuel (natural gas) with biofuel. The calculations show that due to biofuels the company can provide 28% of the school's need for the heating season. The savings will be - 60.6 thousand UAH and its use allow you to save about 43% of fuel annually.

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. The scaling up and promotion of energy production technologies from alternative sources can reduce carbon emissions, which has been an urgent problem globally.

The article is devoted to the current state and analysis of factors affecting the use of alternative energy sources on a global scale. There is a constant growth in volumes energy consumption, which is associated with the stability of the global economy, increasing costs for heating and cooling in various parts of the world. At the same time in the most densely populated areas (China, India), coal accounts for up to 80 % of the energy balance, which leads to an increase in CO2 emissions. In this regard, the article notes the need to switch to the use of alternative energy sources (wind, solar, hydro, geothermal and biomass, nuclear energy). The article analysis the current state of energy sources in developed countries according to statistics for 2018. The authors concludes that the growth rate of renewable energy resources is insufficient, despite their advantage over traditional sources. In this regard, the factors affecting the efficiency of renewable energy sources were summarized. In addition, the article identifies barriers that prevent the acceleration of the rate of replacing traditional energy sources with RES. At the same time, state support measures and relevant legislative acts play a special role in stimulating and attracting the necessary investments.

Abstract The everyday use of renewable energy sources is necessary and indispensable in today’s modern world, partly because of the difficult handling of environmental problems caused by the increasing use of fossil energy sources, and partly because of the still increasing energy demand. Concerning alternative energy sources, Hungary has great potential in geothermal energy, which can mean a breakout especially for the peripheral, disadvantaged micro-regions while developing their future strategies. This was the motivation of our research. In our study, we intended to highlight the economic development perspectives of the Hungarian micro-regions lagging behind regarding the renewable energy potential.

The article considers the legal basis for the formation and development of the country's energy sector, in particular, the issue of energy production from renewable sources, among which the leading place belongs to wind energy. The tendencies of the world energy market, which minimize the negative impact on the environment, as well as the tendencies of development of this branch in Ukraine are investigated. It was stated that for our country wind energy is one of the strategic directions of development of the sector of alternative energy sources, given the high dependence of the country on imported energy, primarily natural gas, and significant potential for wind power, taking into account the location, climate and terrain. However, unfortunately, the pace of development of wind energy in Ukraine still lags significantly behind European ones. It is noted that the legislative provision of the use of wind energy in Ukraine as a source of alternative energy is characterized primarily by the number of bylaws, general declarative legislation, as well as some inconsistencies in legal regulation. An analysis of current legislation and a number of regulations governing the development of the industry in general and wind energy in particular. A review of the norms that relate purely to the issues of the research area and their features and direction of legal regulation. In addition, it was stressed that Ukraine's accession to European initiatives, as well as borrowing international experience in this area should positively affect the energy balance and ensure the development of the sector, in particular, in the light of the need to create a full competitive environment in Ukraine's energy market; changes in heat generation by renewable energy sources and the full transformation of coal regions, which means the gradual closure of unprofitable enterprises with the parallel creation of alternative jobs in these regions.

The article examines topical problems of the role of international organizations in the direction of the development of alternative energy and strengthening of energy security in the world. Considerable attention is paid to the importance of the introduction and development of alternative energy in the context of ensuring environmental human rights and economic well-being. Analyzed the main international legal treaties regulating the reduction of greenhouse gas emissions into the atmosphere and the use of alternative renewable energy sources. The main international governmental and non-governmental organizations in the direction of ensuring environmental and energy security have been identified. Attention is drawn to the need to strengthen the role of these organizations by strengthening the functions of supervision and monitoring to increase the possibility of influencing states that do not comply with the provisions of signed and ratified international conventions. It is concluded that it is necessary to adjust the vector of development of instruments for the protection of environmental rights in the direction of its world globalization. The existing global concept for the development of alternative energy sources requires changes. Given that the environmental problem is universal and, although to one degree or another, it still affects every person, regardless of country or nationality, the obligation to protect the environment must be universal, fulfilled and enforced not only by the government bodies of sovereign states, but also international government organizations. It is noted that the programs and recommendations of international organizations are developed directly for individual states, taking into account their geographical and economic location when choosing the types and methods of developing alternative energy.
