Given the rising cost of crude oil and fuels based on it, as well as acute environmental problems, alternative energy sources are becoming increasingly important. Natural gas is the most affordable alternative fuel for Russia. A study was carried out at FSUE NAMI on the conversion of the L6 engine from diesel to natural gas. The study included testing of gas fuel equipment both to determine its performance and to test its stability at low temperatures. The greatest interest was the selection of gas injectors for distributed gas supply to ensure the required cycle flow rate. Motorless tests of electronic gas injectors BOSCH, IMPCO, WOODWARD, as well as gas injectors produced by Concern KEMZ JSC were carried out. Based on the results obtained, the choice of gas injectors for further use in the gas engine was justified.

The research was a response to the search for alternative energy sources and the assessment of their profitability and legitimacy of use. The assessment used combined energy sources in the form of wind, solar, and natural gas energy. The research was carried out in various locations with varying degrees of sunlight and in various wind zones, which was motivated by the adopted strategy of increasing the importance of non-conventional energy sources and reducing greenhouse gas emissions. The evaluation was performed using the Homer Grid software. The studies showed the justification for the use of hybrid energy sources, combining renewable and non-renewable sources, at the current stage of development. In the conditions of the Lubuskie Voivodeship, the level of insolation was more important than the more favourable wind zone in such a model. Higher economic efficiency of the hybrid model was obtained in the southern location, with slightly less favourable conditions for wind installations. At the same time, the investments were economically profitable and allowed for their return in the perspective of at least eleven years, even at current prices.

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.

Energy sources Oil and natural gas are of great importance in international competition and its impact on international relations, as well as the importance of oil and natural gas in maintaining the position of countries in the hegemony and the global economy as well as the level of economic development. Which calls on the major economic powers to pay attention to this type of energy sources and try to obtain more, whether through bilateral economic agreements and attention to the investment process or through wars, as happened in the US war on Iraq in 2003, which indicates the importance of obtaining On oil in various ways and push the international forces to compete for this vital product, especially in light of the inability of alternative energy sources to compensate oil in industries and at least to reduce the importance of consuming countries by this on the one hand, and on the other hand, the rise in the price of global markets made The producing countries are of importance to the industrial countries, and in maintaining access roads without obstacles or problems that may hinder their arrival, creating another economic crisis in light of the economic and financial crises witnessed by the global economic system
