A completely manageable problem. Also, from your article: "Previous studies that examined this question relied on data from European wind farms — however, wind turbines in offshore wind farms located in or planned for the U.S. Outer Continental Shelf are larger, and spaced farther apart than those included in past studies."
Wind power is no solution to climate change. But neither is it evil.
