How does a wind turbine work?

A wind turbine turns wind energy into electricity using the aerodynamic force from the rotor blades, which work like an airplane wing or helicopter rotor blade. When wind flows across the blade, the air pressure on one side of the blade decreases. The difference in air pressure across the two sides of the blade creates both lift and drag.

How do wind turbine rotor blades work?

Rotor blades use the same “lift” principle: below the wing, the stream of air produces overpressure; above the wing, the stream of air creates a vacuum. These forces cause the rotor to spin. As the wind turbine rotor blades rotate with their rotational motion, the rotor generates aerodynamic torque from the wind.
