Abstract:

Hydroelectricity plays an important role in reforming the energy structure and promoting the lowcarbon development in China.The Three Gorges Project is a typical green energy program,for its electricity production,prevention and control of flood and cargo transport abilities bringing about huge emission reduction.In this paper,we calculated the greenhouse gas emission of the Three Gorges Project,according to the CDM method.The results showed that the emission of the project was neglectable.Also,we conducted a series of field measurement to quantify the greenhouse gas emission from the Three Gorges Region from Oct.2009 to Jun.2010.The outcome showed that the Three Gorges Project emitted 243 milligram greenhouse gas,including CO2,CH4 and N2O per kilowatthour,which was far lower than the level of other kinds of energy sources.Although the water source was abundant in China,the hydroelectricity was still poor explored and the energy consumption was mainly relied on nonrenewable sources.Therefore,hydroelectricity still has potential in developing lowcarbon strategy in China
