Abstract
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.
Highlights
IntroductionThe relevance of the research topic is due to both global trends and the specifics of countries characterized by the isolation of territories in individual regions
Analysis of the global renewable energy market over the past year demonstrates a significant reduction in energy prices obtained by generating energy from renewable energy sources
Data for the 3rd quarter of 2019 show that energy produced from fossil sources in the world market is much more expensive than energy generated from renewable energy sources
Summary
The relevance of the research topic is due to both global trends and the specifics of countries characterized by the isolation of territories in individual regions. Eleven million people today are employed in the renewable energy industry worldwide and an increasing number of countries are discovering the benefits of renewable energy (RES). National support programs, coupled with cost reduction due to technological progress and the need to respond to the challenges of climate change, have stimulated a sharp increase in renewable energy and the development of employment in the industry. The development of renewable energy sources all over the world is facing serious economic challenges for state budgets and consumers, restrictions on the area under renewable energy sources, issues of utilization of equipment, environmental consequences, as well as political challenges
