Wind Mill
Wind power is cost-effective Because the electricity from wind farms is sold at a fixed price over a long period of time and its fuel is free, wind energy mitigates the price uncertainty that fuel costs add to traditional sources of energy.
- It's a clean fuel source.
- Wind energy doesn't pollute the air like power plants that rely on combustion of fossil fuels, such as coal or natural gas.
- Wind turbines don't produce atmospheric emissions that cause acid rain or greenhouse gasses.
