Wind turbines at sunset, forming part of a wind farm. Wind turbines are used to generate electricity from the winds formed by the heating of the Earth by the Sun. They are an environmentally-friendly source of energy, as they release no toxic waste products and do not rely on a limited resource for fuel. Photographed in 2008, near La Muela in the province of Zaragoza, Aragon, Spain. As of 2016, there were 371 wind turbines operating in the La Muela region. | |
