Abstract:

Using an evaluation system of from the well-to-wheel (WTW) and the greenhouse gases, regulated emissions, and energy use in transportation (GREET) model proposed by the Argonne National Laboratory, USA, controlling variables, emissions and energy consumption of both traditional and electric vehicles can be calculated. The WTW calculation methods and GREET model put forward by the U.S. Department of Argonne National Laboratory are used to compare environmental and economic implications of conventional, hybrid, electric and hydrogen fuel cell vehicles in their whole life cycle. Four countries are then compared with different energy structures, differences about electric cars can be seen from energy consumption and emissions. Differences in energy consumption and emission exist in pure electric vehicles between countries using fossil energy and countries using new energy. From the data, it can be concluded that countries using new energy is given priority to develop pure electric vehicles with less emissions. Thus energy and power structures affect the environmental implication of new energy vehicles.

Key words: energy structure, greenhouse gases, regulated emissions, and energy use in transportation (GREET) model, well-to-wheel (WTW)evaluation system, new energy vehicle
