Are electric cars environmentally friendly?

The paper aims to investigate whether electric cars are environmentally friendly. With the growing global awareness of environmental issues, the impact of automobile emissions on the environment has become a major concern. Many countries are implementing measures to replace fuel cars with new energy-efficient electric vehicles, which will have a significant impact on both the environment and the international economy. This paper discusses the environmental impact of the shift towards electric vehicles, focusing on two aspects: the energy materials used and the evaluation standards for automobiles.
