High Quality Content by WIKIPEDIA articles! There are several wind power projects operating in the commonwealth of Pennsylvania and several future wind farms planned or under construction. The most productive wind energy regions generally fall in mountain or coastal terrains. The northern portion of the Appalachian chain, including most of Southwestern Pennsylvania, is one of the areas with the highest potential for wind energy in the Eastern United States. The mountain ridges of central and northeastern Pennsylvania, including the Poconos in the eastern part of the state, offer some of the best wind resources in the region.
