Marketing component of green technologies energy efficiency at traditional and renewable energy facilities

Abstract

The article examines the economic aspects of the production of electrical engineering and electricity at traditional and renewable energy facilities. The authors emphasized that Ukraine has great potential for the development of wind and solar energy capacities, but the relatively high current price of such technologies compared to conservative sources of electricity generation makes new power generation capacities from RES twice as expensive. The authors consider, improving energy efficiency could significantly reduce the growth in energy consumption: according to the International Energy Agency, the implementation of measures to improve energy efficiency on a global scale by 2030 would lead to an increase in energy consumption by 40%, while failure to implement these measures would mean a 60% increase in demand. It is proved that in Ukraine the most promising direction is the use of solar energy. The authors focused on the direct conversion of wind and solar energy into direct current electrical energy. The possibility of converting wind and solar energy into thermal energy without preliminary concentration of the solar radiation flux for heating the coolant and subsequent supply to heating objects has been proved. It was noted that a significant modernization of power plants using renewable energy sources or the construction of additional capacities (for an amount exceeding 50% of their initial cost) after 2014, 2020 led to a reduction in the rates of the “green” tariff for the entire power plant by 10%, 20% respectively and will lead to 2024 by 30%.
