RES development trends that determine the sustainable development of the energy system of the future

To ensure reliable energy supply, it is necessary to solve a number of basic tasks: flexibility of energy systems, uninterrupted supply of energy, its availability to end consumers, resource efficiency and environmental safety. Sustainable development of the energy system involves changes along the entire energy conversion - chain from fuel and renewable generation and transmission of energy to optimizing its consumption. Many countries prioritize the development of renewable energy as the basis for low-carbon economic growth. Renewable energy sources contribute to the development of popular technologies not only in the field of sun and wind, but also in energy storage, hydrogen cycle, electric transport and e-mobility, energy efficiency of buildings, in the field of “smart” technologies, which ultimately affects improving the quality of life of people
