Wind

FromAberdeen Renewable Energy Group

Interesting Facts- A wind turbine generates electricity from the power of the wind. When the wind blows, the turbine blades turn a generator inside the turbine that converts the movement into electricity. That power is then transmitted through underground cables.So a wind turbine is rather like a giant fan in reverse!, Wind turbines generate electricity from wind speeds of 4 to 5 metres per second (10 miles an hour) upwards. They only stop working when wind speeds reach severe gale force, at about 25 metres per second (50+ miles/hour). Currently the fastest growing source of renewable energy in the world.
