 It has been researched 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 stocks of organic fuels, sharp increase in their prices, imperfections and low efficiency of their use technologies, harmful effects on the environment.  It is explored that changing the energy dependence situation can be done 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 high-speed energy crops.  It is researched that in the 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.

 It is analyzed that 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 are 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 it is this industry that is a serious source of alternative energy production.  This applies not only to large agro-holdings of animals but also to small households that operate in rural areas, for which the maintenance of animals in a subsidiary state may be a source of energy supplies for their own needs.  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 the use of gas turbines and boiler-wastes is additional.  In this case, thermal efficiency can reach more than 90%.

 It is concluded that one of the ways to reduce the dependence on energy imports and the improvement of ecology in rural areas of Ukraine is to develop alternative energy through a powerful 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 same competitive environment for different types of fuel.  This will give green energy green light.
