A wind turbine will not make a significant dent in your electric bill unless you live in a place where the wind blows pretty hard most of the time. Even in a very windy location, it may take 10 years for to generate enough power to pay for the initial cost. Windmills are designed to produce maximum power at a particular wind speed; at half that speed, they produce only one eighth as much power.
Here’s a link for some commercially available windmills. If you build your own, it will probably be much less efficient. In most cases, the price tag does not include a tower or installation.
Check your electric bill to see how many kilowatt hours you use during your windy season. Divide by the number of hours in the billing period to get the average power consumption.
Before deciding on a windmill, you should compare against other options. In urban communities with lots of sunshine, solar is best. Gasification is a much more attractive option for areas that don’t get much wind or sunshine. However, the gas turbines that go with them tend to be pretty noisy, so they are not suitable for crowded urban communities.

First, a quick check with your local building department will tell you whether it’s forbidden, and if not, whether there’s even a chance they will issue you a building permit for it. Check with your neighbors, since if they object, you’re unlikely to get a permit. Unless you’re a certified professional engineer with lots of time on your hands to do the research, hire a professional to evaluate your site and advise you on options. You need steady, strong winds much of the time.
Since wind is intermittent, you need either a grid connection or lots of (expensive) storage.
In my opinion, this is not a practical technology for home deployment.

You have several problems of which the cost would be the greatest. The wind doesn’t always blow so you’ll need batteries and a converter to AC. Then there’s high winds that can tear down your windmill, lightning strikes, annoyed neighbors, city ordinances, house insurance premiums and did I mention the really, really high cost.
Go to the Northern Tool Company. I believe their website is the same. They sell this sort of thing. You have to have the wind blades, a mast, supply your own concrete foundations, a PTO power generator, the storage batteries, converters, regulators, wire, power transfer switches. You’re talking about 35 to 50k, easily.
