I don't suppose you've yet put up your turbine? I'd like to hear how it is working out ASAP. Indeed, I'd think you'd want to find out ASAP as well. If you can really get that sort of power with 10 turbines, and you get good wind fairly often and throughout the year then a present value analysis should reveal it to be a no brainer. Which begs the question you are already asking: why isn't everyone already doing it?
It is tempting in such circumstances to presume the answer is "because there is something wrong with the idea". But in reality is is because most people are unconscious and unimaginative. Radiant floor heating and, especially, passive solar heating and MASSIVE insulation should have been standard in ALL new construction which requires winter heating decades ago, but it isn't. They would save you a fortune. Your heating bill in NH could probably have been reduced by 90% (okay...so you are going to tell me you heat with "free" wood...so lets say 90% in CALORIES). Humans tend to be dumber than the proverbial doorknob with only rare exceptions.
I just entered a sell-buy order on my etf only to find it won't take effect until tuesday. Ugh!
