Abstract: With the continuous progress of social production technology and the increasing number of vehicles, the problem of environment and energy has become increasingly prominent. Based on the consumption of oil resources in China in 2016 and the energy structure of the State Grid, the CO2 emission of traditional fuel vehicles and pure electric vehicles in the process of circulation was calculated. If half of the fuel consumption in 2016 was replaced by electricity, a additional power generation of 809.6 bill. kW·h woule be needed, which accounted for 13.18% of the total power generation in 2016. To cut CO2 emissions by half and mainly replace gasoline vehicles with electric vehicles, more than 190 million additional electric vehicles needed to be added and charging power of 570.06×106 kW would be increased, which put forward higher requirements for the current grid load. Compared with the electrification of traditional fuel vehicles, reasonable reduction of coal consumption in power grid structure has more positive significance for reducing CO2 emissions.
