Coal Consumption and As Emission in Electricity Generation in China under Different Energy Scenarios

This paper presents coal consumption of electricity generation in China under different energy scenarios of the given long-term energy policies. Long Range Energy Alternatives Planning 2008(LEAP 2008) software is used to develop a simple model of electricity demand and to estimate gross coal consumption of electricity generation in China until 2030 under these scenarios. And, time-serial emission inventory of As is also built in the method of emission factors based on fuel consumptions. The results show that the coal consumption will increase by 4 times ,amounting to 5.92 billion tees under BAU scenario. The total emission of As is 20.7 Mtces with an average annual growth rate of 6.6%. Under ENR scenario, the total reduction of coal consumption and As emission may reach 25.89% and 26.82% respectively compared to that in BAU scenario.
