What's old is new again when it comes to windmills and wind power. Wind farms with dozens of enormous steel windmills are cropping up all over the Midwest. And it's becoming trendy for eco-friendly colleges and businesses to put up their own windmills to produce power. But just a few individual farmers have had the courage to put one up. Wind power to generate a farm's energy needs makes a lot of sense and hopefully more farmers will get on this bandwagon.
