The limited world resources, energy dependence and the threat of global warming have long led many countries to understand the importance of developing renewable energy. The most developed branches of renewable energy today are solar and wind energy. Solar energy is the most powerful environmentally friendly source of energy, and most importantly, it is practically free. It can be used for a variety of purposes, from providing power to individual homes, to space satellites and ships. We will talk about the problems of the formation of this industry in today’s interview with Dmytro Lukomskyi, Ph.D., an expert in solar energy.
