  • How much do wind turbines cost Windustry

    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). Wind turbines have significant economies of scale. Smaller farm or residential scale turbines cost less overall but are more expensive
