How are wind turbine data collected?

The U.S. Wind Turbine Database project compiles wind turbine information from the Federal Aviation Administration (FAA), Lawrence Berkeley National Laboratory’s (LBNL) Wind Technologies Market Report dataset, the American Wind Energy Association’s (AWEA) wind turbine and project datasets, and the United States Geological Survey’s (USGS) legacy (2014) wind turbine dataset, as well as online sources. User feedback is also incorporated once verified with other sources.

The turbine position is verified by visual interpretation using high-resolution aerial imagery.

A detailed description of the data collection and verification process can be found in this webinar.

What materials are used to make wind turbines?

According to a report from the National Renewable Energy Laboratory , wind turbines are predominantly made of steel (71-79% of total turbine mass), fiberglass, resin, or plastic (11-16%), iron or cast iron (5- 17%), copper (1%), and aluminum (0-2%). According to the 2017 Wind Technologies Market Report , many turbine components are domestically...

Can wind turbines harm wildlife?

A key challenge facing the wind industry is the potential for turbines to adversely affect wild animals both directly, via collisions, as well as indirectly due to noise pollution, habitat loss, and reduced survival or reproduction. Among the most impacted wildlife are birds and bats, which by eating destructive insects provide billions of dollars...

How many wind turbines are installed in the U.S. each year?

The number of turbines installed in the U.S. each year varies based on a number of factors, but on average 3,000 turbines have been built in the U.S. each year since 2005. Learn more: Wind Energy U.S. Wind Turbine Database

Where can I find wind turbines that are permitted but not built?

The Federal Aviation Administration (FAA) maintains a database of proposed turbines that they are evaluating as potential obstructions to airspace. However, an FAA determination of “non-hazard” is just one step of many in the permitting process, and many turbines evaluated by the FAA are never built. Learn more: U.S. Wind Turbine Database

How do I cite the U.S. Wind Turbine Database if I want to use the data?

We suggest the following citation for use in academic papers and where applicable: Hoen, B.D., Diffendorfer, J.E., Rand, J.T., Kramer, L.A., Garrity, C.P., Hunt, H.E. (<year of USWTDB access>) United States Wind Turbine Database. U.S. Geological Survey, American Wind Energy Association, and Lawrence Berkeley National Laboratory data release...

How many turbines are contained in the U.S. Wind Turbine Database?

As of January 2019, the U.S. Wind Turbine Database (USWTDB) contains more than 58,000 turbines. These turbines have all been constructed since 1980 in approximately 1,500 wind power projects spanning at least 43 states (plus Puerto Rico and Guam).

Why is it important to know the locations of wind turbines?

No publicly-available, national database of wind turbines existed prior to the creation of the USGS Windfarm mapper, which was replaced with the U.S. Wind Turbine Database (USWTDB) in 2018. Knowing the location of individual turbines and their technical specifications creates new opportunities for research and improved siting and is important...
