Wind turbine. The blades of the turbine are turned by the wind, which produces electricity. Wind power is an important environmentally-friendly source of energy. It produces no waste and is cheap to maintain once it has been set up. The generation of energy from the wind is a long-term alternative to the finite energy supplies of fossil fuels.
