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 the United States
By 2014, the wind industry in the USA was able to produce more power at lower cost by using taller wind turbines with longer blades, capturing the faster winds at higher elevations. This opened up new opportunities and in Indiana, Michigan, and Ohio, the price of power from wind turbines built 300 feet to 400 feet above the ground competed with conventional fossil fuels like coal. Prices had fallen to about 4 cents per kilowatt-hour in some cases and utilities had been increasing the amount of wind energy in their portfolio, saying it is their cheapest option. For power contracts made in the year 2014, the average price of wind power fell to 2.5¢/kWh.
