Analysis of Modern Methodological Approaches to Assessing the Energy Efficiency of Enterprises and Industrial Complexes

The production process is always characterized by energy consumption, so production efficiency is characterized, among other things, by rationality and efficiency of energy use. The high degree of automation and mechanization of modern production determines the need to match the cost of final products and energy costs for their production. The authors considered such indicators as the ratio of energy consumption to GDP and per capita, specific energy consumption to GDP growth, kg/ USD, energy consumption per unit of output. At that time, the concept of “energy intensity” was interpreted not as the ratio of energy consumption for manufacturing products to revenue from sales of these products but as the caloric content of a certain type of fuel or as the energy equivalent in units of conventional fuel. The term “energy intensity” was formed as a result of the analysis of energy consumption in the energy sector and various industries. Two types of energy intensity were introduced: total energy intensity of products – the amount of energy and (or) fuel consumption for the manufacture of products, including the cost of mining, transportation, processing of minerals, and production of raw materials, materials, parts, taking into account the utilization rate of raw materials and materials – and energy intensity of product production, which is the amount of energy and/or fuel consumption for the production of products, including the cost of mining, transportation, processing of minerals and production of raw materials, materials, and parts, taking into account the utilization rate of raw materials and materials.
