Electric Vehicles Contribute Fewer Emissions Than Gasoline-Powered Cars Over Their Lifetimes

Q: Are electric cars really better for the environment than gasoline-powered cars over their lifetimes? 

A: Yes. Electric vehicles typically release fewer greenhouse gas emissions than internal combustion engine vehicles during their life cycles, even after accounting for the increased energy required to make their batteries. And their carbon footprints are expected to get smaller in the near future.
