Wind power uses the naturally occurring energy of the wind for practical purposes like generating electricity, charging batteries, or pumping water. Wind turbines capture the kinetic energy in the wind, converting it into electrical energy. Utility-scale turbines are mounted on tall towers, usually 300 feet or more above the earth's surface where the wind is faster and less turbulent. In utility-scale power applications, anywhere from one or two to several hundred turbines are connected to the utility grid, providing electricity when the wind blows.
