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.

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.

It has been substatiated in the article that renewable energy sources have recently become one of the important criteria for the sustainable development of rural areas. The emphasis is placed on the search for new and improved existing technologies for the production of alternative energy sources, expansion of their implementation areas. It is substantiated that the main reasons for such attention to the energy supply of rural territories are expected exhaustion of fossile fuels resourses, sharp increase in their prices, imperfections and low efficiency of their use technologies, harmful effects on the environment. It is shown that the situation of energy dependence can be changed by conducting the corresponding energy policy, improving the regulatory framework and attracting investment in the development of non-traditional and renewable energy sources. It is highlighted that Ukraine has sufficient opportunities to provide an adequate amount of biofuels, primarily through the use of biomass potential of agricultural crops and fast-growing energy crops. It is researched that in conditions of a complex socio-economic situation in Ukraine, a significant energy dependence on energy imports, the search for alternative energy sources is of particular relevance. It is estimated that Ukraine is among the dozens of countries - the largest consumers of energy resources, with a small share in the structure of the world's product. It is proved that energy saving today becomes one of the most important priorities of socio-economic development in the national and regional dimensions. The necessary condition for successful work in national and world agrarian markets is constant work on increasing the competitiveness of products, in particular, reducing its value by reducing the energy intensity of production. It is substantiated that agricultural producers are actively working on the issue of reducing energy consumption per unit of output. It is determined that the majority of these measures is aimed at increasing the productivity of agricultural crops, increasing productivity of the livestock sector, technical and technological re-equipment of the production process. It was emphasized that special attention should be paid to the branches of animal husbandry, because this industry is a serious source of alternative energy production. This applies not only the large live-stock producing agro-holdings but also the small households that operate in rural areas, for which live-stock production is subsidied by the state. Besides, it may become a source of energy supplies for their own needs as well. It was investigated that each year large livestock farms and poultry farms can receive environmentally friendly biofuels in an anaerobic way and significantly improve the quality of sewage. It is determined that thermal efficiency of cogeneration units of biogas production depends very much on equipment for electricity generation. For example, the use of gas-fired internal combustion engines has a thermal efficiency of 70% to 75%, while in the case of using gas turbines and boiler-wastes thermal efficiency can reach more than 90%. It is concluded that one of the ways to reduce the dependence on energy imports and to improve ecology in rural areas of Ukraine is to develop alternative energy generation in agro-industrial complex. Ukraine should create all opportunities for the development of innovative technologies for the implementation of renewable energy sources; to provide conditions for serial production and implementation of bioenergy facilities; to promote the formation of the equal competitive environment for different types of fuel. This will promote green energy production

Problem setting. Transformation of social relations, as well as the state of the natural environment necessitate the study of the origins of development and the formation of Ukrainian legislation in this area. Rapid rates of man-made load, depletion of natural resources, impossibility (or slow) recovery of natural resources - all these are factors that encourage rapid further steps towards innovative solutions to the use and protection of the environment. Alternative energy sources, the so-called renewable energy sources, are becoming increasingly popular due to their potential and environmental and economic characteristics of use. The object of the origins of the development of legal relations on the use and protection of the environment in the field of innovation. The subject of the study is the historical aspects of the regulation of legal relations on the use and protection of the environment in the field of innovation. The state of research of the problem. The origins of scientific research on the relationship between the use and protection of the environment have repeatedly attracted the attention of researchers. In particular, in this area there were publications of legal scholars: A.P. Hetman, H.V. Anisimova, V.L. Bredikhina, M.V. Krasnova, Y.S. Shemshuchenko, N.R. Malysheva, G.N. Polyanskaya, V.G. Emelyanova, V.V. Nosik and others. However, the study that would be aimed at analyzing the normative regulation of legal relations on the use and protection of the environment in the field of innovation has not yet been, which prompted us to choose this topic of research. The target of this research is to identify and analyze the origins of legislation and scientific achievements in this area. Scientific novelty is the search for and further development of an effective mechanism for regulating the legal relationship between the use and protection of the environment in the field of innovation. Article’s main body. The historical continuity and recurrence of the main legal forms, as emphasized in the literature, make it possible to predict the direction of further development of legislation taking into account the maximum use of valuable historical experience, on the one hand, and avoid future use of legal forms that have failed. Conclusions. Today we can conclude that nature management is irrational, leads to depletion (or disappearance) of natural resources, there is a violation of the ecological balance of natural systems - as a result of rising Earth temperature, destruction of ecosystems, deteriorating human health. Rapid population growth has been observed with great progress, and industrial development has contributed to the increase in energy consumption and the use of non-renewable energy resources, the mass consumption of which has had negative consequences for the environment. Unlike countries with more developed economies, Ukraine is only at the beginning of its path of saving the environment, but instead continues to operate an extensive type of economic development. Natural resources are not used efficiently enough, and if we do not take decisive action, we can already have irreversible consequences. The answer to this should be alternative energy sources - renewable, resource-saving, waste-free (low-waste).
