I have always wondered if you would be able to cobble up a wind turbine out of an old automobile alternator, a couple of deep cycle batteries and an inverter, if it would be possible ( and feasible) to generate enough power to operate choice loads throughout a house ( lighting, and perhaps the fridge and freezer. Nothing big really, just something that could be bolted up atop an unused T.V antenna that it seems many people still have bolted to the sides of their houses, well at least around here they do.. Put the inverter and batteries in the basement and there ya MIGHT have a limited but cheap source of "green" power.
Just a thought....
