The U.S. Geological Survey's interactive windFarm map provides detailed information on wind farms across the United States, including Alaska and Hawaii.

By zooming in on the map, users can find the precise location of tens of thousands of individual turbines, with information for each turbine including the owner, generating capacity, on-line date, type of tower, blade length, total height, and the confidence with which this information can be given.

The turbines can be filtered by height, blade length, and generating capacity. The map also includes a layer showing federal lands, colored according to the jurisdictions of each federal land management agency.

The map data are freely available to download in a variety of formats for a variety of purposes: GIS files, Google Earth overlays (.kmz), Excel spreadsheets, and more.
