Promising Directions of Increasing Energy Efficiency and Development of Green Energy in the Household Sector of Ukraine

The aim of the article is to identify promising directions for increasing energy efficiency in the household sector of Ukraine, focusing on green energy. The study involved a graphical, analytical and prognostic methods, in particular the trend analysis of polynomial regression. The study was based on data on the volumes of generation, RES (renewable energy sources) consumption, and the tariff for renewable energy for 2014-2022. The forecast covered a period of 8 quarters. Solar power plants are the most popular renewable energy source among households. The high tariff for the sale of such energy and the ease of installation of solar power plants are key factors in choosing this method of generating electricity from renewable sources. Household solar power plants account for 11% of the total solar power plant capacity in the country. The number and capacity of these plants are predicted to double every 2 years, which will ensure a proportional increase in household income from the sale of electricity generated by solar power plants. The results of the study open up prospects for studying the payback terms and economic efficiency of using different sources of renewable energy in different regions of Ukraine, which is especially important for households and utilities.
