The aim of the study is to analyze the technologies of conversion of renewable energy sources for use as a motor fuel. The raw energy medium primarily includes hydrocarbon compounds, which process of thermochemical transformation is accompanied by the release of the main target component - hydrogen. The presence of the hydrogen component causes unique kinetic and environmental indicators of its combustion, high efficiency of the engine operating cycle. Esters are derivatives of organic or inorganic acids and alcohols, they are found mainly in essential oils and make up the bulk of vegetable and animal oils. Currently, dimethyl ether is considered as one of the most promising fuels for diesel engines. In this regard, the transfer of diesels on the air does not require special measures for the forced ignition of the combustible mixture. If the raw material origin and the cost of production of dimethyl ether are taken into account, this is the most promising motor fuel. A positive property of vegetable oils is the ability to mix in any proportions with gasoline, kerosene and diesel fuel, which allows to obtain biofuels with desired physical and chemical properties. The article deals with esters, methods of their production, vegetable oils. It describes the ways to achieve the necessary properties of alternative energy as motor fuel. The results of the comparative analysis of processing technologies of renewable energy in the fuel for automotive engines are given. It substantiates the potential use of alternative energy sources in the energy structure of the agricultural complex.renewable energyalcoholvegetable oilsesterswater-biofuel emulsionsynthetic fuelsвозобновляемые источники энергииспиртырастительные маслаэфирыводно-биотопливные эмульсиисинтетические топлива[Кавтарадзе З.Р., Кавтарадзе Р.З.
