The term “wind energy” typically refers to the generation of electricity from the wind.
The term “wind energy” usually refers to the generation of [[Energy|electricity]] from the wind.


In the typical [[Wind turbine|horizontal-axis 3-blade design]], the kinetic energy of the wind creates lift on one side of each blade in the same way as an airplane wing. The blades thus pull themselves around and turn the rotor hub on which they are mounted, which turns a turbine that generates electricity.
In the typical [[Wind turbine|horizontal-axis upwind 3-blade design]], each blade is more rounded on one side so that the kinetic energy of the wind creates a vacuum in the same way that an airplane wing works. The blades are thus pulled around and turn the rotor hub on which they are mounted, which turns a turbine that generates electricity.
