In the U.S. state ofPennsylvania,wind power is one of the primary sources ofrenewable energy, and accounts for over one third of the state's renewable energy production.[1] There are more than 27wind farms currently operating in the Commonwealth of Pennsylvania. Theoretically, theenergetic development of these wind farms could provide power for nearly 350,000 homes, or 1,300 megawatts.[2] A majority of the farms are located in the southwest-central and northeastern regions of the state.[3] Pennsylvania is an East Coast leader in wind energy due to its natural wind resources and governmental incentives brought on by the state. There is a lot of potential for growth within the wind power industry in Pennsylvania and the Northeast. Despite being one of the few landlocked states in theMid-Atlantic region, Pennsylvania is close to several offshore sites along the coast of theAtlantic Ocean.
Wind power is also environmentally friendly. Wind power is efficient to create and sustain because it creates 31 times moreenergy than it requires during the manufacturing process and over its 20 year lifetime.[4]
If all wind energy potential in Pennsylvania were developed with utility-scalewind turbines, the power produced each year would be enough to supply 6.4% of the state's currentelectricity consumption.[5] In 2016, the state had 1369 megawatts (MW) ofwind powered electricitygenerating capacity, responsible for 1.6% of in-state electricity production.[6] This increased to 1459 MW in 2020.[7]

In 2000, Pennsylvania's first commercial wind farm, theGreen Mountain Wind Energy Center, was completed inSomerset County, but deactivated in 2015.[8]
In 2006, the statelegislature ruled that wind turbines and related equipment may not be included inproperty-tax assessments. Instead, the sites of wind facilities are assessed for theirincome-capitalization value. [9]
In 2007,Montgomery County became the first wind-poweredcounty in the nation, with a two-year commitment to buy 100 percent of its electricity from a combination of wind energy and renewable energy credits derived from wind energy.[10]
Voluntary agreements with wind energy companies in Pennsylvania have been signed by The Pennsylvania Game Commission to avoid, minimize, and potentially mitigate any adverse impacts the development and production of wind energy may have on the state's wildlife resources.[11]
Many smaller wind farms in Pennsylvania are operated byNextEra Energy Resources, based inFlorida.[12]

In recent years, there have been advancements in both on and offshore wind power in Pennsylvania. At least 1300 MW of wind power is currently[when?] installed at the 27 wind farms in Pennsylvania.[14] According to the U.S. energy information administration, 1 MW of wind power can power about 650 average American homes.[15]
Offshore wind power has been proposed on the state's limited shoreline onLake Erie.[16]
