Abstract
The study deals with the dynamics of the actual Ukrainian gross domestic product (GDP), the level of its energy intensity as a criterion of evaluating the energy security of the national economy. The level of consuming fuel and energy resources in Ukraine for the last seven years was evaluated. The author built a correlation model of dependency of the actual Ukrainian GDP on total fuel consumption volume by Ukrainian industry, industrial production volume, degree of wear of fixed production assets, number of enterprises using advanced production technologies. National economic losses due to non-efficient use of fuel and energy resources were calculated on the basis of the correlation model. The pace of GDP increase was also calculated. The model of functional dependency of national economy energy efficiency on the level of actual Ukrainian GDP energy intensity and transfer from separate values to determinants was made by index method.
Highlights
The development of society is closely linked to the state of the energy sector
renewable energy sources (RES) can be used to supply consumers with energy. They can work together with the traditional energy supply system, providing part of the energy consumed to reduce the cost of energy consumed
The results of the study of heat supply systems based on RES show their efficiency
Summary
The development of society is closely linked to the state of the energy sector. In these conditions, it is necessary to develop the energy sector itself, and at a faster pace. For the development of the energy sector it is necessary to introduce new innovative technologies aimed at energy saving, according to the Federal Law No 261 “On energy saving and energy efficiency” (An et al, 2019a). Reducing the consumption of fuel energy resources through innovative technologies is an urgent task. In the energy supply system to increase its energy efficiency it is necessary to reduce energy losses during its transmission. Creation of economically effective and ecologically safe energy supply system is possible based on renewable energy sources (RES) (An et al, 2019b; An et al, 2019c)
