摘要：The purpose of this paper is to assess the effectiveness of investment projects in terms of ensuring energy security and sustainable economic development of construction enterprises and public utilities sector. The study revealed that existing methods for assessing the efficiency of energy-saving projects in public utilities sector are often local in nature and do not contribute to energy security. A methodology is needed for the economic feasibility of energy demand at affordable prices in the domestic and foreign markets. As a result, the authors proposed a method for solving the problem of rational use of fuel and energy resources in a system of three sectors: capital construction, public utilities sector, and the fuel and energy industry as interrelated sectors of the economy and the economic turnover of fuel and energy resources.
