Set amid the Allegheny Mountains near Altoona, Pennsylvania, the Allegheny Ridge Wind Farm will be the state’s largest wind farm and one of the largest in the mid-Atlantic region when complete in a few years. Under development by Gamesa Energy USA, a wholly owned subsidiary of Spanish wind-energy company Gamesa Group, the first phase of the project was completed in October 2007 and includes 40 turbines able to produce 80 megawatts of renewable power. The second phase, called the North Allegheny Wind Farm LLC, is in progress and will include 35 windmills.

At the time of its construction, the Hoover Dam was the world's tallest dam and the largest hydroelectric producer of its kind. It is considered an engineering marvel, most notably for its ingenious concrete column construction, sheer size and speed of construction.
