Wind Power

Windmills have been used since 200 B.C. to convert wind energy into a more usable form. Modern wind turbines are horizontal-axis wind turbines which include a rotor shaft and electric generated at the top of the tower upon which the turbine rotates. Wind farms, like those located north of Greater Lafayette, typically include three-bladed turbines that are pointed into the wind through the use of computer-controlled motors. These turbines can reach speeds of 200 miles per hour at the tip of each turbine, are relatively efficient, and relatively reliable.
