The cost of residential wind turbines varies depending on how much power they can produce and other factors. A rough range is $4,000 to $8,000 per rated kilowatt. A system that would offset most of an average home's electricity use (10,000 kwh/year) will cost roughly $50,000 before incentives.
How Much Power Does a Wind Turbine Generate? | …
Wind turbines commonly produce considerably less than rated capacity, which is the maximum amount of power it could produce if it ran all the time. For example, a 1.5-megawatt wind turbine with an efficiency factor of 33 percent may produce only half a megawatt in a year — less if the wind isn't blowing reliably.
