People like pointing out how dirty the electricity grid mix is after charging electric vehicles. Many love talking about plug-in cars that as they say contribute to pollution.
This map from Carnegie Mellon University helps on finding out the cleanest cars based on their location. Researchers have compiled information about the gas emissions of different EVs considering their charge, they compared gasoline-powered vehicles to electric ones. In the research were tested Nissan Leaf, Chevrolet Volt, Prius Plug-In Hybrid versus Toyota Prius hybrid and Mazda 3.
By driving a Nissan Leaf in California, Florida or Texas you'll leave a carboon footprint much lower than Toyota Prius would. On the same time you will leave a larger footprint with the same Nissan comparing to Toyota Prius if you're driving in the Midwest or South. If you're from Midwest you'd better choose a Mazda 3 it would leave the lowest footprint. Chevrolet Bolt will have a larger footprint than Prius if it drives through the country, but it's gonna be smaller than Mazda 3 would leave in the biggest part of urban counties of U.S. Prius Plug-In and Prius are almost equal across the U.S.
This graphic is very helpful for those who want to buy a clean car, now you'll know the real differences between the gasoline cars and electric cars.
