Currently used power generation methods are used for thermal power generation using a large fossil fuel, nuclear power generation using uranium, and hydroelectric power generation that requires large-scale desalination facilities. Thermal power plants need to generate power by burning fuel such as coal or petroleum. Therefore, a lot of combustion gas is generated, which increases air pollution. Nuclear power does not emit combustion gases polluting the air, but a large amount of radiation waste that is fatal to the human body is generated. It is discharged, hydroelectric power does not emit a combustion gas or radiation waste, etc. and does not require a separate fuel, while destroying the environment there is a problem that is not environmentally friendly.
Recently, research on solar power generation and wind power generation, which is environmentally friendly and can use fuel permanently, is being actively conducted.
