Wind farm turbines in Iowa. 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. As of 2013, Iowa had the third-highest wind power capacity of all the US states. Photographed in July 2014, near Pomeroy, Iowa, USA.
