The results of studies aimed at the improvement of methods of the determination of share of the total energy consumption of the production related to measures on the environment protection are presented. We propose a new method allowing one to calculate it in the case where the enterprise uses the existing refinery or replaces it in the course of modernization on the basis of data available in the literature or related to a specific enterprise. The energy consumption of measures on the environment protection is considered as a sum of three components which involve the purification of waste gases, sewage treatment, and neutralization of solid waste. For their calculation, new formulas are developed.The method is applied for calculation of the energy consumption for the environment protection in the production of concrete by dry method which amounts to 3.4 - 5.1 kg of equiv. fuel/ton of concrete, depending on the type of refinery. It is shown that the purification of waste gases takes 4.5 - 12% of the electric power consumed by the concrete production. On the scale of the branch producing 10 mln ton of concrete for year, the mean electric energy consumption for the purification of waste gases is 90 mln kWh/year.The proposed method can be used for any production in all branches of the industry and types of the economic activity.
