A wind power project was begun on Mars Hill Mountain in the fall of 2006. A total of 28 GE 1.5 MW wind turbines were installed along the ridge and northern section of the mountain. The windmills are assembled in multiple parts. The towers, which are composed of three sections stacked together have a combined weight of 20,000 pounds, and are tall. Each of the turbine's three blades (together, a rotor) are approximately long, with a total rotor diameter of approximately . The rotor diameters of the turbines are comparable to the wingspan of a Boeing 747.
