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
The capacity credit of wind is estimated by determining the capacity of conventional plants displaced by wind power, whilst maintaining the same degree of system security. According to the American Wind Energy Association, production of wind power in the United States in 2015 avoided consumption of 73 billion gallons of water and reduced emissions by 132 million metric tons, while providing USD 7.3 bn in public health savings.
