The underlying data set is also available.
From the U.S. Department of the Interior:
[The U.S. Department of the Interior] and the U.S. Geological Survey [recently released] the first publicly available interactive map and geo-dataset showing more than 47,000 onshore wind turbine locations and related information across the entire United States.
The wind turbine map, which includes turbines installed as of July 2013, was created by combining publicly available data sets from the Federal Aviation Administration, the U.S. Energy Information Administration, the Oak Ridge National Laboratory, as well as other federal, state and local sources. USGS researchers also identified additional turbines not in those pre-existing databases and added them to the dataset and map. The locations of all turbines were visually verified using high-resolution imagery. The location of each turbine was verified to within plus or minus 10 meters, and its technical specifications were assigned based on the make and model.
Before the release of the interactive map today, some individual state maps with turbine information and national maps of facility information existed, but there were no national maps with turbine-specific information and verified locations.
