In this April 18, 2013, photo, a golden eagle is seen flying over a  wind turbine on Duke energy's top of the world windfarm in Converse County Wyo. The company has reported 10 golden eagle deaths since it started operation in 2009. It's the not-so-green secret of the nation's wind-energy boom: Spinning turbines are killing thousands of federally protected birds, including eagles, each year. (AP Photo/Dina Cappiello)
