There are two different designs for wind turbines.  The horizontal wind turbine is more popular and uses tilted blades to generate friction against the wind.  This causes the blades to turn. The other design for wind turbines is the vertical design.  This design finishes with the entire structure spinning circularly after the wind causes it to turn on a middle point on the surface.  Both designs use the wind to spin the blades that in turn spin the generator inside.  It is the complete opposite process of a regular fan.  The turbines use mechanical energy to produce electrical energy instead of using electricity to produce mechanical motion like a fan.
