What are the comparative advantages of new energy vehicles and traditional vehicles?

The comparative advantage of new energy vehicles and traditional vehicles is that new energy vehicles are more environmentally friendly. It changes the dependence of cars on fossil fuels, which is conducive to alleviating the oil crisis and changing the energy structure of society, and will not emit harmful gases to the outside world when working. New energy vehicles also have the advantages of low noise and more comfort. The noise and vibration levels during operation are much lower than those of traditional internal combustion engines. At idle speed and low speed, the comfort of electric vehicles is much higher than that of traditional vehicles. With the increase of vehicle speed, tire noise and wind noise become the main noise sources and return to the same level. New energy vehicles also have the advantage of energy saving. Electric vehicles consume about 100 km 15-20 kwh. Considering the loss of power plant and motor, the energy consumption per 100 kilometers is about 7 kilograms of standard coal. According to the fuel consumption per 100 kilometers 100 L, the energy consumption of traditional cars is about 10kg standard coal, which will be higher in urban congestion environment. New energy vehicles have a purchase tax exemption policy, which is cheap to maintain and unlimited in many cities.
