Energy utilization as a growth driver in the circular economy

Energy utilization, as an element of waste management, is a significant factor in the development of the circular economy, is a factor of energy and green growth, which determines the object area of research – energy economics. The subject area of the research is energy utilization as a growth factor of the circular economy – reproduction of energy resources. The purpose of the study is to reveal the theoretical content of the subject of research and the form of manifestation in the economy of a closed cycle. Research objectives required to achieve the research objective: 1. Study of various theoretical and practical achievements of scientific research by domestic and foreign authors; 2. Theoretical analysis of the phenomenon; 3. Formulation of research results. The methodology of the research is expressed in the use of economic and statistical methods of data processing with heuristic analysis of information. Research results: 1. The concept of energy utilization is clarified; 2. The concepts of cogeneration and trigeneration as factors of energy utilization are considered; 3. The use of thermal gas power plants is justified as the most energy-efficient and economical option within the framework of energy utilization. The theoretical significance of the research lies in the relevance of the subject area, the content of which implies the transition to fundamentally new mechanisms of economic activity, cost savings, minimization of waste and resources, the formation of additional value in the process of reuse of resources.
