The American Wind Energy Association (AWEA) estimates that, if wind energy is pursued "aggressively," it could account for 20% of US electricity demand by 2020. Factors slowing the expansion of wind energy include questions raised by environmentalists concerned with the number of birds killed by the turbine blades. A new report by the Department of Defense also raises concerns that tall windmills in some locations could degrade the capabilities of air-defense and air traffic control radars. So far, radar-related concerns have resulted in delays of some energy projects, but no cancellations. AWEA Executive Director Randall Swisher says, "Decades of experience tell us that wind and radar can coexist. The American wind energy industry will continue to work collaboratively with government and others."
