Driving through west Texas, there's a few oil fields, a lot of farms, and a lot of wind farms. Aesthetically I don't exactly like the windmills, but I don't mind them. Texas has a lot of very ecologically stressed areas with mass scale habitat loss thanks to big ag farming, oil, and other human development, but the areas where the windmills are are either a wash where it's mixed wind farm/crop farm areas or they're habitat that's affected by the windmills but still has a lot of habitat. While there are bird strikes, the ecological impact of the windills is by far the least serious compared to coal/gas/oil.
Also I live in Austin, and while some windmills froze early because the power company didn't pay for weatherizing, they were the fastest to fix and managed to excel over nuclear, gas, and coal at production. All of them failed because private power companies didn't want to pay to weatherize, but in areas where wind is really reliable it's a rare thing - a reliable, clean energy source like hydro can be.
It's for those reasons that I really am pro-windmill. We really need mixed sources of reliable clean energy sources if we care about future generations of humans, wind is a great one.
