There are lying trolls who spew their anti-EV hatred over the social media, and they’re stupid for claiming the ‘dirty grid’ makes the EVs pollute. That’s absurd to blame EVs for something they have no control over, and that’s not their fault. But these are myths; EVs don’t pollute as much as ICEVs – cars that use gasoline.
