Abstract
Evaluation of the impact of energy efficiency on the activities of the oil and gas sector enterprise Gazprom, PJSC has been given. By using the tools of correlation and regression analysis it was proved that investing in resource-saving and environmental technologies can improve the energy efficiency of an enterprise, reduce the negative impact on the environment, increase the amount of profit to be distributed among shareholders and improve profitability by reducing costs. As a result of building an economic and mathematical model for Gazprom, PJSC it was found that investments aimed at protecting the environment and rational use of natural resources in the amount of 1 billion rubles lead to savings in fuel and energy resources aimed at own needs in the amount of 0.1 million tons of standard fuel annually. The savings achieved are reflected in the return on sales, which increases by 0.429%. Energy efficiency is improved as a result of technical changes that allow the company to provide the same services with less energy consumption. For this reason, investments in energy-saving technologies are key to improving the energy efficiency of oil and gas companies, as they reduce operating costs and improve operating performance by reducing energy consumption. The matrix of Pearson’s correlation coefficients is illustrated. Analysis of scientific sources was carried out confirming the importance of studying the impact of energy efficiency on the activities of enterprises. Conclusions are drawn about the need for research in the field of energy efficiency of the oil and gas industry of the economy and its parameters.
