Electric Cars Create Pollution to Environment
Transportation usually caused three types of pollution to our environment: air pollution, noise pollution and electromagnetic wave pollution, among which air pollution will destroy the earth’s ecological system and bring irreparable damage to mankind. Exhaust emissions from vehicle exhaust pipes are mainly due to the incomplete combustion of motor fuel. The main components are carbon monoxide, hydrocarbons, nitrogen oxides, carbon dioxide, lead, and a variety of particles. The hazard of air pollution is wide and it is hard to prevent. Most people think that gasoline vehicles exhaust emissions are the major concerns of air pollution, so that in many countries they have already enforced some regulations and developed fuel-efficient cars to reduce pollution. But through recent researches and news, I found that in many locations, electric cars create much more pollution than gasoline vehicles to our environment.
Although electric cars discharge smaller pollutants than fossil fuel vehicles do, the power of electric cars comes from electricity, which means we must undertake responsibility for mitigating pollutant emissions from power generation. In the United States, it is believed that power stations are more efficient and cleaner than fossil fuels, which is good news for electric cars. In addition, emissions far from cities and households have less impact on people's health, and if electricity is generated through renewable energy, the impact on the environment is negligible. However, considering the different national conditions, we may see an electric car running on electricity made from coal has the same or worse environmental impact as gasoline vehicles.
Take China as an example, China’s energy resources are still dominated by coal, and thermal power would continue to dominate Chinese power structure for a long time. There are 68% of electricity from coal power generation in China, so electric cars emissions higher than gasoline vehicles. In recent years, air pollution become more serious in some large cities. Thermal power is the biggest emission source of nitrogen oxides in China, and the second largest source of PM2.5 in some cities after motor vehicles. Nitrogen oxides and PM2.5 emissions are the main reasons for frequent occurrence of urban haze and photochemical smog. At present in some urban areas, there are still coal-fired power plants in operation. Even though its emission level has reached the most stringent emission standard, they are still not conducive to the improvement of urban air quality because of the special geographical conditions of these urban areas.
In Jan.26, 2017, American Economic Review published a study shows that electric cars are worse for the environment than gas-powered cars, mostly because of the Midwest’s reliance on coal for electricity. If we want to create a sustainable network, we need to pay more attention on developing green energy on a national level. Once governments support more subsidies to these types of power, we can really achieve zero-emission from electric cars, and transportation would not be one of threats to our environment.

Many people really think that electric vehicles are zero displacement, but in fact it is powered by car power, driving the wheel with the motor. If the electric vehicle increases dramatically, haze increases, deteriorating the atmospheric environment. The popularity of electric vehicles varies according to national conditions. China's charging pile is building fast, but far from reaching the point of popularity. The road to universalization is a long way off. With the development of new energy technologies, especially the development of nuclear power will provide more environmentally friendly solutions for the supply of electricity. At that time, new energy vehicles will lead a new trend.
