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).maller farm or residential scale turbines cost less overall, but are more expensive per kilowatt of energy producing capacity. Oftentimes there are tax and other incentives that can dramatically reduce the cost of a wind project.
The first all-steel windmill and tower was produced by the United States Wind Engine & Pump Co. The first electricity-generating wind turbine was invented in 1888 in Cleveland, Ohio by Charles F. Brush.The turbineâs diameter was 17 meters (50 feet), it had 144 rotor blades made of cedar wood, and it generated about 12 kilowatts (kW) of power.ith current tax credits, wind energy offers American customers the cheapest electrical energy option. At a cost of $35 per Megawatt hours (MWh), wind is cheaper than coal at $37 per MWh and natural gas at $50 per MWh (in 2004 dollars).
