Abstract
Vehicle electrification has been seriously considered as an industrial revolution to achieve sustainable transportation in China. With the development of the electric system, electric vehicles and railway systems are utilizing and generalizing. To accurately and adequately evaluate the energy consumption and CO2 emission effects of fuel and electric vehicles, this study focuses on these two kinds of vehicles, including buses and cars, and analyses their environmental impacts. Results show that electric vehicles consume less heat energy and release less CO2 emission than fuel vehicles do at the same distance. Public vehicles consume much less heat energy than private cars no matter which kind of fuel they use. In addition, the CO2 emission of fuel cars is larger than that of fuel buses. Moreover, electric energy is cheaper than gasoline and diesel. Therefore, the electric power will benefit the environment and society. The power should be recommended to substitute oil in the future. Although electric vehicles still have some limitations, such as prolonging the life of batteries, developing new energy, and green energy can guarantee energy security and benefit the environment and reduce the emission of CO2.
Highlights
A surge of the vehicle population in China since the 1990s has been primarily due to rapid economic growth and urbanization and has triggered great concern about energy security in the country
The energy use of road traffic is a considerable part of it, and it is closely related to environmental problems, so the government is immensely concerned about this issue
It is believed that using new energy can make contributions to the reduction of CO2 emissions
Summary
A surge of the vehicle population in China since the 1990s has been primarily due to rapid economic growth and urbanization and has triggered great concern about energy security in the country. The associated CO2 and air pollutant emissions increase pose a severe challenge to CO2 mitigation and urban air quality improvement. Using new energy has become a developmental trend, from industry to daily life. The energy use of road traffic is a considerable part of it, and it is closely related to environmental problems, so the government is immensely concerned about this issue. The main environmental contribution of road traffic is the energy use of fuel vehicles. To reduce the impact of fuel vehicles, electricpowered vehicles are more and more widely used. It is believed that using new energy can make contributions to the reduction of CO2 emissions
