Wind turbine at a wind farm at sunset. 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. As there is an infinite supply of the wind, it is a long-term alternative to the finite fossil fuel energies. Photographed at Ystumtuen, Wales.
