While hybrid and plug-in hybrid electric vehicles still use gas, battery-electric vehicles and hydrogen fuel-cell vehicles do not, and as such, do not directly produce any smog-forming, toxic pollutants. California’s electricity grid is one of the greenest in the nation, so when you charge your EV you are fueling it with the cleanest energy available. If you have solar panels on your home, you are driving with an almost net-zero environmental impact.
