Wind

In support of the Department of Interior’s Powering Our Future Initiative, the USGS will utilize research, modeling, and monitoring data to develop a quantitative methodology to assess the wildlife impacts at a national level.   The USGS has extensive...
Yes. Bats are being found beneath wind turbines all over the world. Bat fatalities have now been documented at most wind facilities in the U.S. and Canada and it is estimated that tens to hundreds of thousands die at wind turbines in North America each...
No, the USGS will produce a peer-reviewed, externally vetted methodology for assessing wind effects on wildlife. Usually the USGS applies the methodologies we develop to a variety of energy resources, resulting in resource endowment estimations. In the...
All sources of energy have environmental effects to varying degrees. Wind energy can affect both wildlife and their habitats. Wildlife impacts include potential bird and bat mortality from collisions or near-collisions with turbine blades and in some...
Unfortunately, it’s not clear yet. 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 observed at wind turbine facilities are from species known...
USGS has a multi-center research plan that partners with several universities that seeks to answer the following issues: better identify the seasonal distributions, habitat needs, and migration patterns of species showing greatest susceptibility continue...
USGS created the first publicly available national map of onshore wind turbines. Available national maps of wind power facilities existed, but did not include the location of individual turbines or turbine-level details. Maps of turbines did exist for...
In general, bats seek out a variety of daytime retreats such as caves, rock crevices, old buildings, bridges, mines and trees. Different species require different roost sites. Some species, such as the Mexican free- tailed and gray bats live in large...
Knowing the location of individual turbines, as well as information such as the make, model, height, capacity, and area of the turbine blades, creates new opportunities for research and improved siting, and is important information for land and resource...
No, USGS also looks at the environmental effects of activities associated with a range of energy resources, including air and water impacts from fossil energy occurrence, development, and utilization; produced waters from oil and gas drilling; and...
