Welcome to IEA Wind Member Country Activities for the
In the United States, 13,131 MW of wind power capacity came online in 2012, more than any other year and nearly twice as much as was installed in 2011. This added wind capacity represented 43% of new U.S. electricity generation capacity for 2012, surpassing the 33% of new generation represented by natural gas.
Wind energy now accounts for nearly 3.5% of national electricity consumption in the United States and is deployed in 39 states and territories. The state of Texas alone has more installed wind power than all but five countries around the world.
The record installations in 2012 represented a rush to complete projects before the pending expiration of a key federal incentive for wind energy—the Production Tax Credit (PTC). In January 2013, as part of the American Taxpayer Relief Act of 2012, the U.S. Congress extended the incentive for one year and changed the eligibility requirement so that rather than being in operation, farms must be under construction by the end of the year.
Moving aggressively to advance offshore wind deployment, the U.S. Department of Energy (DOE) Wind Program is pursuing its 168 million USD (127 million EUR) offshore wind initiative. In 2012, DOE announced seven Phase 1 funding awards to plan and design offshore wind demonstration projects. In Phase 2, three of these technology demonstration partnerships will be selected to move to demonstration of full-scale offshore wind generation facilities. Offshore wind facility developments were further facilitated with the adoption of the American Wind Energy Association (AWEA) Offshore Compliance Recommended Practices that address the unique conditions for wind energy development in U.S. waters.
Other important R&D activities support technology development. Tests of large wind turbine blades began at the Massachusetts Wind Technology Testing Center that has been certified by the International Electrotechnical Commission (IEC).
Development and testing of advanced drivetrains continues, and researchers are increasing efforts to understand the reliability of wind turbine components and complex flow in wind facilities. The United States is leading a new IEA Wind research task to assess and monitor the environmental impacts of land-based and offshore wind development. Read the entire report here
