How energy transformed in windmills

Explain how is energy transformed in the windmills?

Basically what happens is that as the energy from the wind rotates the vanes of mill, coils of wire rotate within a permanent magnet (or generator) and generate electric voltage or current. This current is then sent to the grid and used by us as the electricity which is another form of energy. This is a much simple description and there is a lot more in the design of the system.
