California's wind farms are killing thousands of birds every year. What's to be done? Here's one solution:
If environmentalists and state officials have their way, the towering windmills that dot the Altamont Pass will be replaced and moved to prevent the killing of thousands of birds annually, including species protected under federal and state laws.Yeah, they could do that. Or they could encase the existing turbines in a protective cage, by using some version of this breakthrough technology.
In an effort to curtail the carnage, they say the turbines -- which provide one-third of California's wind power -- should be newer, taller models and be concentrated on the leeward side of the hills.
I wonder which solution would be cheaper and more effective?
