Home or Farm Scale Wind Turbines. Wind turbines under 100 kilowatts cost roughly $3,000 to $8,000 per kilowatt of capacity. A 10 kilowatt machine (the size needed to power a large home) might have an installed cost of $50,000-$80,000 (or more).
Offshore wind is considerably more expensive, with costs of between USD 0.10 and USD 0.21/kWh. The regional weighted average installed costs for onshore wind range from around USD 1 280/kW to USD 2 290/kW.China and India have weighted average installed costs 35% to 44% lower than in other regions.he cost of electricity from wind is falling. This is due to total installed costs declining in line with lower wind turbine prices since 2009 and, at the same, technology improvements mean more wind is harvested from the same site with new wind turbine technologies.
