A home wind turbine costs $20,000 to $80,000 for a complete wind power system large enough to meet an average home's full energy demands. The total cost depends on the turbine size, type, capacity, and location. Dramatic Cost Range: Wind turbine costs span from $700 for small residential units to over $20 million for offshore turbines, with total project costs varying from $10,000 to $4,000+ per kW installed depending on scale and location. Total installed costs for utility-scale onshore wind have continued to decline, but they are beginning to stabilize as. How much do commercial wind turbines cost?
