The environmental costs of power generation have been studied

a calculation model

which involves nine kinds of power generation mode and suitable for national conditions of our country

being established

and being analysed by taking Guiyang Power Plant as an example.Using said model

the environmental costs of power generation in power plants can be calculated by adopting conventional data

and based on actual condition of the power plant.Results of analysis and calculation show that the maximal environmental cost in eastern area having a very large population in our country is coal-fired power generation

being 21.7 cents kWh;the minimal environmental cost is wind power generation

being 0.6 cents/kWh.
