Earlier today, on a ridge-top in southwestern Pennsylvania, wind-powered energy took another step forward with the dedication of two new "wind farms" that will produce enough electricity to run 8,000 homes.

One of the wind farms is in Somerset county, where six wind turbines overlook one of the highest points along the Pennsylvania Turnpike. The other sits more than 2500 feet above sea level along a strip of pastureland on Laurel Mountain, just miles from Frank Lloyd Wright's world-famous Fallingwater. There, ten turbines whirl atop towers that reach 230 feet into the air.

The electricity produced at the Laurel Mountain wind farm and at an even larger one planned near Scranton, PA, already has a market. Exelon, which was formed last year following the merger of Philadelphia-based Peco Energy and Chicago's Unicom Corporation, will buy the wind-produced electricity for the next 20 years.
