THE MODERN METHODS OF USING ALTERNATIVE ENERGY SOURCES
Author: Uchqun Mirzayev, Tulakov Jakhongir Turakul ugli
Abstract:
At present, much attention is paid to the use of solar energy. Solar energy, in addition to traditional energy, is ecologically clean while changing. The rarity and the rising cost of fuel is one of the main problems of the scientific technique, which is the acquisition of infinite resources of solar energy. Further research and experiments on the use of solar energy, as well as the use of solar power plants in a number of countries, shows that solar energy can be widely used today based on modern technical capacities.
