Homemade wind generator questions?

I have questions about making my own windmill I have an alternator our of a Plymouth acclaim, anyway I was thinking about overhauling it to be a more efficient generator. If I do this and it works is it practical to get a simple inverter and pump the AC voltage in my electric meter? It will not produce enough power for my needs but if I do this would it not reduce my electric bill as far as me selling back some power? Also do you need a special electric meter to do something like this?
