This article reviews how electric vehicles help the environment compared to traditional gas-powered cars. The researchers studied different stages of an electric car’s life cycle, like making the materials, running the car, and recycling the battery. They found that in terms of carbon dioxide emissions, electric vehicles are better than gas cars when looking at overall use but worse during the manufacturing stage. Future research should focus on areas like hydrogen fuel cell cars, different types of electric vehicles, water usage, and better ways to evaluate environmental impact. Overall, electric and hybrid cars produce less CO2 pollution than gas cars when you consider the entire process from energy creation to driving.
