Wind, Birds and the Power Grid

David Cassuto

Let’s be clear: Our hero favors alternative energy, including wind power.   However, nothing is all good and wind turbines kill birds.  The U.S. Fish and Wildlife Service estimates that more than 400,000 birds are killed each year by blows from the blades of wind turbines.  And as the Department of Energy moves ahead with its (laudable) goal of transitioning the nation’s power supply to 20% wind power, measures must be taken to protect the avians at risk.  According to the American Bird Conservancy, the golden eagle, whooping crane, and the greater sage-grouse—face “especially severe” threats from wind energy and are most at risk from “poorly planned and sited wind projects.”  The American Wind Energy Association disputes the dimensions of the threat, claiming that “A reasonable, conservative estimate is that of every 10,000 human-related bird deaths in the U.S. today, wind plants cause less than one. The
National Academy of Sciences estimated in 2006 that wind energy is responsible for less than 0.003% of (3 of every 100,000) bird deaths caused by human (and feline) activities.”   Continue reading
