Oh baby! Have I got the perfect item for you guys!...
Just build a couple of these...
http://www.otherpower.com/otherpower_wind.html These can cover all your needs without relying on the grid. As I understand it, if you stay connected to the grid and create a "surplus" of energy, the utilities have to buy it from you in most states for the same price they would have sold it to you at,(not CA though... that state is just too jacked up! Big, VERY BIG scandles and corruptions in CA over "Power").
