How does wind energy compare to solar energy and other forms on an economic basis?
Wind energy is an economy of scale; a large utility scale wind turbine can cost less than $1000/kW and small wind turbines cost around $3000 – $4000/kW. However, the average citizen interested in clean, renewable energy cannot acquire the millions of dollars needed to by a utility scale wind turbine. Small wind power, on the other hand, is accessible by the individual. Small wind power typically costs $20/kW a year to operate and maintain Solar power in not an economy of scale; a large solar plant is only moderately cheaper on a per kW basis than a small solar power system for a home. The typical cost of a solar panel is around $5000/kWp with an annual operations and maintenance cost of $10/kWp.
