How do wind turbines work?

The huge rotor blades on the front of a wind turbine are the "turbine" part. The blades have a special curved shape, similar to the airfoil wings on a plane. When wind blows past a plane''s wings, it moves them upward with a force we call lift; when it blows past a turbine''s blades, it spins them around instead.
