Wind energy and wildlife stakeholders collaborate to understand wind-wildlife interactions and develop ways to mitigate adverse impacts. These efforts take place in the context of federal laws and state and local requirements. Standardized study methods help stakeholders assess risk, and tools such as the U.S. Fish & Wildlife Service Land-Based Wind Energy Guidelines aid development of wind projects while reducing impacts to wildlife.

By standardizing methods and expanding data accessibility, we are learning more about which species are most at risk from collision fatalities, and where and why. Wind energy facilities may also affect the quality or availability of habitat for some species, although habitat-based impacts are more complicated and less well-understood, and represent an important area for future research.

The first opportunities to avoid wildlife impacts occur during the earliest stages of wind energy project development. Screening prospective sites and predicting risks to wildlife can inform project design and are key to avoiding or minimizing habitat-based impacts. In some cases, project design, including placement of individual turbines, can also help to minimize collision risk for some species.

Technologies and strategies can help minimize bird and bat collisions with operating turbines. Curtailing, or shutting down, turbines during conditions when risk of collisions is higher is a common approach. More sophisticated methods include technologies that detect birds or bats near turbines and either deter them with audible or visual signals or curtail the turbine.
