Abstract
The Ukrainian energy sector is one of the most inflexible energy sectors in the world as a result of the almost complete depreciation of the equipment of the main sources of power supply: nuclear, thermal, and hydropower. In connection with existing problems, there is a need to develop and use new energy-saving technologies based on renewable energy sources. In this proposed research, a regression model of renewable energy growth in the energy sector of Ukraine was developed. The studied literature reveals that the independent use of individual functioning elements of renewable energy sources function as the primary power source that is not an optimal solution for stable energy supply. This study proposes the use of hybrid renewable energy systems, namely a combination of two or more renewable energy sources that will help each other to achieve higher energy efficiency, accelerate the growth of renewable energy in the share of the Ukrainian energy sector and/or improve functioning with battery energy storages. Moreover, the use of hybrid renewable energy systems in Ukraine will reduce the human impact on the environment, realize the potential of local renewable energy resources and also increase the share of electricity generation from renewable energy sources. Therefore, mechanisms for managing state regulation of stimulating the development of hybrid renewable energy systems have been developed.
Highlights
In the present world, the development of the energy sector is a factor that largely determines the vector of the economic development of the country
The Ukrainian energy sector is in serious condition as a result of almost complete depreciation of the equipment of the main sources of power supply: nuclear 55%, thermal 36%, and hydropower 6% [34]
The tasks aimed at increasing the economic return on renewable energy sources, increasing profitability and stimulating their production, are the key steps towards the decentralization of energy supply and European integration of Ukraine
Summary
The development of the energy sector is a factor that largely determines the vector of the economic development of the country. The Ukrainian economy is one of the most energy-intensive in Europe. Considering the current trend of rising energy prices, there is an increase in demand for steel energy-saving solutions in all sectors of the economy. The energy intensity of Ukraine’s Gross Domestic Product (GDP) is several times higher than in the developed countries of Europe. The introduction of renewable energy-saving technologies is necessary to strengthen national energy security and is one of the priority tasks of state policy, as well as an important condition for the sustainable development of the country
