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 of economic benefits to the country’s agricultural sector each year.

How are bats affected by wind turbines?
Dead bats are found beneath wind turbines all over the world. It’s estimated that tens to hundreds of thousands die at wind turbines each year in North America alone. Unfortunately, it’s not yet clear why this is happening. It’s possible that wind turbines interfere with seasonal migration and mating patterns in some species of bats. More than three quarters of the bat fatalities at wind turbines...
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 information for land and resource management. In...
How many homes can an average wind turbine power?
According to the U.S. Energy Information Administration , the average U.S. home uses 893 kilowatt-hours (kWh) of electricity per month. Per the U.S. Wind Turbine Database , the mean capacity of wind turbines that achieved commercial operations in 2020 is 2.75 megawatts (MW). At a 42% capacity factor (i.e., the average among recently built wind turbines in the United States, per the 2021 edition of...
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...
How many turbines are contained in the U.S. Wind Turbine Database?
As of January 2022, the U.S. Wind Turbine Database (USWTDB) contains more than 70,800 turbines. These turbines have all been constructed since 1980 in approximately 1,500 wind power projects spanning at least 44 states (plus Puerto Rico and Guam). Learn more: Wind Energy
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
What materials are used to make wind turbines?
According to a report from the National Renewable Energy Laboratory (Table 30), depending on make and model wind turbines are predominantly made of steel (66-79% of total turbine mass); fiberglass, resin or plastic (11-16%); iron or cast iron (5-17%); copper (1%); and aluminum (0-2%). Many turbine components are domestically sourced and manufactured in the United States. According to the Land...

Wind Turbine Blade
This photo shows one of the three 135-ft blades of a turbine before installation. Although the blades of wind turbines appear to move quite slowly to the human eye, blade tips often move at speeds faster than 100 mph.
