The wind is used to produce electricity using the kinetic energy created by air in motion. This is transformed into electrical energy using wind turbines or wind energy conversion systems. Wind first hits a turbine’s blades, causing them to rotate and turn the turbine connected to them. That changes the kinetic energy to rotational energy, by moving a shaft that is connected to a generator, and thereby producing electrical energy through electromagnetism. The amount of power that can be harvested from wind depends on the size of the turbine and the length of its blades. The output is proportional to the dimensions of the rotor and the cube of the wind speed. Theoretically, when wind speed doubles, wind power potential increases by a factor of eight. Below you can find electrical materials for wind energy projects:
