The society today uses fossil fuels more than ever in history. This results in degradation of the environment, that is, everything that surrounds us. Fossil fuels are a dirty source of energy and all the harmful substances released by their combustion and even poor use, the neglect of people during their mining and transportation can have a disastrous environmental impact. Human dependence on energy is getting bigger and bigger and it starts to realize that it will not be able to use conventional energy sources forever and must turn to something that will produce energy for a long time and will not be harmful to the environment. Renewable energy sources are just one of these ways that a man can provide himself and his grandchildren with a clean energy source that will be more profitable for a long time. Of course, everything has its own price, as well as renewable energy sources. They are manifested by low efficiency, high cost and underdevelopment. Some ways are more promising than others are and have a higher impact unit compared to the funds invested. One of these ways of producing electricity is hydroelectric power plants. They are very expensive and require great work on their construction, they also require maintenance regardless of whether they are in function or not. Of course, they also have a bad impact on the environment and humanity. This can be seen in the example of the Three Georges Dam Hydroelectric Power Plant, which required a displacement of 1.2 million people for its construction. Also after the filling of the reservoir lake, many cultivated areas, hills, forests and finally entire cities flooded. To make the Sun's potential more efficient and cleaner, it is necessary to develop new technologies and to perfect their implementation and use. The new technologies and discoveries that are discovered every day give us tremendous potential in this sector.
