How a wind turbine works

Simply stated, a wind turbine works the opposite of a fan. Instead of using electricity to make wind, a turbine uses wind to make electricity.

The wind turns the blades, which spin a shaft, which connects to a generator and makes electricity The electricity is sent through transmission and distribution lines to a substation, then on to homes, business and schools.

High-tech turbines equal low environmental impact. That’s why wind power is gaining public approval and generating increased awareness.

It is also becoming economically competitive with more conventional power sources – a fact that’s greatly improving its prospects as a viable energy source.
