"The article considers the relevance of the use of autonomous power systems powered by renewable energy sources for use in the agricultural sector in the conditions of the Kostanay region. The main features of energy supply systems from the point of view of the rationality of their construction with a low population density and developed agriculture are considered. The share of the component in the structure of the cost price and tariffs for electricity associated with the generation of electric power is given. The share of electric energy costs in the production of agricultural products is determined and ways to reduce them are outlined. The possibility of using hybrid autonomous power plants for water supply for agricultural needs is considered. The article presents the device and the principle of operation of alternative technologies for obtaining thermal, mechanical and electrical energy using a solar water jet and a greenhouse generator. A comparative analysis of the advantages and disadvantages of the considered alternative technologies is carried out, on the basis of which design changes and improvements to existing structures are proposed. It is proposed to use a Stirling engine to generate mechanical energy in conjunction with a greenhouse generator, allowing the wind generator to generate electrical energy. The main advantages and versatility of the hybrid design, in comparison with the original ones, allowing the use of renewable energy, are noted. "
