Analysis on Economic Benefits of Wind Farms Based on Environmental Benefits

To deepen the current understanding of the economical benefits of wind power,the paper,based on the present emission and sewage discharge cost rate and the U.S standard of environmental values,estimates the total cost of the emission and sewage discharge for a certain thermal power plant according to its own emission and sewage conditions.With this estimation,the environmental benefit of a wind power is calculated.Considering the environmental benefit of wind power,if the unit cost of a thermal power plant is greater than the difference between the unit cost for one KWH during the operation life and the unit environmental benefit,wind power will have better economic benefit and prospects for development.
