The kinetic energy of wind is converted into mechanical kinetic energy, and then the mechanical energy is converted into electric kinetic energy, namely wind power generation. The principle of wind power generation is that wind power drives windmill blades to rotate, and then the rotating speed is increased through a speed increaser, so that a generator is promoted to generate electricity. According to the windmill technique, a breeze speed (of the order of three meters per second) can be used to generate electricity. Wind power generation is forming a hot tide around the world because it does not require the use of fuel and does not produce radiation or air pollution.
