Methodological Principles of Valuation of Energy Efficiency of Crop Production

The article is devoted to substantiating the system of indicators of the energy efficiency of crop production. The methodology for calculating the energy performance of crop production (direct energy costs; indirect energy costs; total energy consumption; total energy stored in crop production; energy profits from crop production; energy efficiency of crop production; coefficient of energy efficiency of crop production; energy intensity of crop production; energy return on crop production) is provided. The main factors are determined that affect the energy efficiency of crop production, such as bioclimatic conditions, the level of technology, the level of technical support, organizational and economic factors. The estimation of energy efficiency of crops in Ukraine is made. The production of sugar beets is found to be most energy consuming, and the largest energy profits can be obtained in the production of grain maize.
