1. Wind energy turns a windmill’s blades on a rotor that is connected to a main shaft. The main shaft spins a generator, producing energy. The amount of energy generated depends on the speed and direction of the wind. One drawback is proximity of the wind generation facilities to the distribution centers and/or to the homes served, which affects the quality and cost of the energy. See also: Energy
2. Electricity produced when wind is captured by turbines and converted into electricity. This is the cheapest, and fastest growing, renewable energy technology.
