As a resident of a fairly windy area, I am always amazed at the level of resistance people offer to wind power. It's free, sustainable, clean, and cheap. There are usually two reasons that anyone actually offers against wind power. The first is noise (from the spinning turbine blades); that one is solved with moving the turbines to remote locations, like unpopulated hillsides or offshore. The second is the one that gets most people up in arms: birds cannot see the spinning blades, and are cut to pieces. This leaves most environmentalists at odds with their bleeding hearts, as clean power that is borne on the back of dead avians seems to be a real gut wrencher. Luckily, along has come this article , which correctly points out that the United States' incredibly large feral cat problem easily eclipses the amount of bird deaths caused by wind power. Windmills? An estimated 40,000 birds each year meet their ends from these power producers. Feral cats? "Hundreds of millions"
