how does wind produce electricity and how can we use biogass

Wind energy:

Air in motion is called wind. It possesses kinetic energy due to its speed. The kinetic energy of wind is is utilised to obtain wind energy.Windmills are used to generate electricity from wind energy. A windmill is a simple machine with a structure similar to a large fan erected at some height.
