Introduction
Recent years, climate change has become a hot topic. Scientists constantly express their concern about the devastating results that the climate change has brought us or about to happen to us. According to a new estimate conducted by Intergovernmental panel on Climate Change, if humans continued using fossil fuels in current rate, the Earth’s average temperature would rise by between 2.6 and 4.8 degrees above pre-industrial levels by 2100, which may result in a series of catastrophic consequences, such as sea level rising, or more frequent extreme weather condition etc. (IPCC, 2015). One of the reason that climate is changing in such a fast pace is because of the high demand and consumption of gasoline. U.S. Energy Information Administration stated that “Light-duty vehicles (cars, sport utility vehicles, and small trucks) account for about 90% of all gasoline consumption in the United States” (U.S. Energy Information Administration, 2015). Therefore, finding an approach to cut down the gasoline usage has become an urgent issue. Electric vehicle has become one of the solutions to reduce the demand for petroleum, thus helping alleviate the environmental stress caused by carbon dioxide emission. Although, the PEV market share in the U.S. is only 0.66% as of December 2015 (Cobb, 2016), the fact that PEV can help transit the energy usage to more efficient and greener mode gives PEV plenty of potentials. The prevalence of electric vehicles will result in growth of
