How Wind Energy Works
Wind turbines capture the kinetic energy in the wind, converting it into electrical energy. Utility-scale turbines are mounted on tall towers, usually 100 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.
Wind speed is a critical feature of wind resources, because the energy in wind is proportional to the cube of the wind speed. In other words, a stronger wind means a lot more power.
