Wind energy is one of the fastest growing sources of new electricity supply in the United States. As wind development continues to grow and expand to new areas of the country, so does the possibility that some turbines would be located within the line of site of radar systems. If not mitigated, such wind development could cause clutter and interference for radar systems involved in air traffic control, weather forecasting, homeland security, and national defense missions.

This fact sheet summarizes the work the U.S. Department of Energy and its national labs have done to minimize the effects of wind turbines on radar.
