Energy policy of the United States
U.S. wind power installed capacity now exceeds 65,000MW. For calendar year 2014, the electricity produced from wind power in the United States amounted to 181.79 terawatt-hours, or 4.44% of all generated electrical energy. Texas is firmly established as the leader in wind power development, followed by Iowa and California.
Wind power in Pennsylvania
If all wind energy potential in Pennsylvania was developed with utility-scale wind turbines, the power produced each year would be enough to supply 6.4% of the state's current electricity consumption. In 2016 the state had 1369 megawatts (MW) of wind powered electricity generating capacity, responsible for 1.6% of in-state electricity production.
