Massive Offshore Wind Turbines Safe for Birds
Infrared monitoring shows that savvy seabirds steer clear of wind turbines.
Uncertainty surrounding wind power's impact on wildlife--particularly the potential for deadly collisions between birds and turbines--has tarnished its image and even delayed some wind farms. Indeed, the first large offshore wind farm proposed for U.S. waters--the Cape Wind project in Massachusetts's Nantucket Sound--has been held up in part by concerns that its 130 turbines could kill thousands of seabirds annually. Now a simple infrared collision-detection system developed by Denmark's National Environmental Research Institute is helping clear the air.
