Residential wind turbines vary 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. Again, if you don’t have consistent wind speeds high enough to spin the turbine regularly (10-12 mph), the investment probably doesn’t make sense.
