Wind Maps and Data

WINDExchange provides wind maps and anemometer data to help homeowners, communities, states, and regions learn more about their available wind resources and plan wind energy projects. WINDExchange also maintains more than a decade of installed capacity maps showing how wind energy has progressed across the United States over time as advances in wind technology and materials make wind resources more available.

Anemometer Loan Programs and Data

Anemometer data can help businesses, developers, farmers, ranchers, homeowners, and municipalities determine whether there is enough wind energy at a site to make a wind turbine investment economically feasible. Each anemometer collects wind-speed data in 10-minute intervals. Such data can also aid windfarm developers in determining whether an area is suitable for developing a large-scale wind farm.

The U.S. Department of Energy's Anemometer Loan Program (ALP) was active from 2000–2011, resulting in the installation of anemometers at 90 locations. In addition, the ALP provided support for the installation of anemometers at 38 additional locations under a related program administered by the Western Area Power Administration. The ALP was also used as a template for approximately 20 state-administered ALPs.

The Native American ALP consisted of a suite of lending programs along with outreach activities, such as an annual Wind Energy Applications Training Symposium (WEATS), support to the DOE’s Tribal Energy Program (TEP), and occasional technical assistance. Approximately one-quarter of the borrowing tribes submitted a successful TEP grant application after receiving an anemometer loan.

The ALP's history, lessons learned, and summary findings are available in an NREL report.
