The function of the wind turbine is to extract energy from the wind. The wind is flowing air, which has speed and therefore kinetic energy. When the wind flows through the wind turbine blades, part of the kinetic energy is transferred to the wind turbine to make it rotate. The wind turbine gains energy, and the wind loses energy, so the wind speed after flowing through the wind turbine will slow down. This article explains the calculation methods of wind energy and wind turbine power and efficiency, and provides a video to make it easier to understand.
