How much does a wind turbine cost to power a house?
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.
How do you calculate the cost of a wind turbine?
Take the monthly kWh production. Multiply that by the number of months the turbine is expected to last, and divide the result into the cost of the turbine. The number you end up with is the cost per kWh over the lifetime of the turbine.
