The importance of promoting new energy vehicles in environmental protection is a significant step towards improving urban air quality and achieving carbon neutrality targets. With rapid urbanization, the quantity of traditional fuel vehicles dramatically increases, leading to more severe air pollution issues. Vehicle exhaust emissions are one of the major sources of harmful urban gases such as PM2.5 and nitrogen oxides, severely affecting people's health. Electric vehicles do not produce exhaust during their operation, reducing the emission of pollutants from the source. Additionally, the energy efficiency of electric vehicles surpasses that of traditional fuel vehicles, which means they emit fewer greenhouse gases while producing the same amount of energy. Thus, the development of new energy vehicles, particularly electric cars, alongside building charging infrastructure plays a considerable role in reducing urban air pollution. Moreover, establishing new energy charging infrastructures aids in advancing the smart grid. Efficient electricity allocation and management facilitated by a smart grid lessens energy waste and optimizes its use. Pairing this with power generation from renewable energy sources, such as wind and solar, can lead to a more environmentally friendly electricity supply and further propel the carbon neutrality effort.
