Well, as always, it depends on your definition of being cost effective. To get a nice cheap Skystream Windmill would be about $15,000 taxes in. This would produce enough power to comfortably provide electricity for a house or a small business (around here around 500kw a month). With proper battery and storage, one could go completely off the grid saving about 100 bucks a month. Doing that, it would take just over 15 years to get ones money back, but you can find that good will comes putting up wind towers, price of electricity doesn't go up over the years, and that your initial investment doesn't have much concern about spending 15 grand in one shot. If you are creative the rotor itself is about $5,000.00 without mounting or foundation, but if you were to basically put a hole in the ground with a giant pipe sticking up 60 feet for less than $10,000 you can save some serious money there. People might wonder why I know this, and it's because I just ordered a couple for my company.
