Growth of Farms Puts More Birds At Risk Introduction A 2008 Department of Energy report calls for the U.S. to generate 20% of its electricity from wind by 2030. By then, experts expect wind turbines to kill at least one million birds each year, and probably significantly more, depending on how many turbines developers build over that time. Wind farms are also expected to impact almost 20,000 square miles of terrestrial habitat, and over 4,000 square miles of marine habitat by 2030, some critical to threatened species. Deaths will come to birds who hold our identity and imagination, like Bald Eagles and other raptors. Turbines also kill birds listed as threatened or endangered unless developers carefully plan and implement wind farms. Onshore, these species include Golden Eagles, Whooping Cranes, sage-grouse, prairie-chickens, and many migratory songbirds. Offshore, species at risk include Brown Pelicans, Northern Gannets, sea ducks, loons, and terns, among other bird
