A 100kW rated turbine may average perhaps 10kw on a typical day so if the wind blew for 24 hrs ( rare in most areas) you would be close on many days. On good days you would have plenty, on other days you would have nothing.
Anything below 20kW is not going to give you much of a saving on the average day.
Throw in the lack of space, presumably in an urban area and VAWT, save your money. If you have sun think of solar. Otherwise conserve energy as a starting point.
Going towards solar is best option i have. Just thinking of spending $800(my budget) on these experiments and trying.
