The Answer May Be Blowing In The Wind
Six new small wind turbines, recently installed by the county, sit atop the east side of the Government Services Center Wednesday Feb. 13, 2008 in downtown Duluth, Minn. The project, which cost nearly $80,000, generates up to 6,000 watts of electricity for free when the wind blows. (AP Photo/Duluth News Tribune, Bob King)
Modern wind turbines reach up to 300 feet above the ground, with the diameter of the rotor and blades reaching more than 250 feet. Lying on the ground, a three-bladed rotor can almost cover a football field. One this size can produce enough electricity to power 1400 homes. The larger the turbines (blades), the more power. The smaller ones which are used for an all-electric home or small business have rotors between 8 and 25 feet in diameter and stand about 30 feet high. Wind turbines consist of three main parts: the tower, the blades and the nacelle. A nacelle is the size of a small motor home. The nacelle houses the generator, which transforms wind into electricity. Simply put, the wind turns the blades, the blades spin a shaft, this connects to a generator and makes electricity.
