No surprise here for most EV drivers, but still good to see in black and white. Electric cars charged on the grid generally have a lower carbon footprint than internal-combustion vehicles–and their wells-to-wheels carbon emissions only shrink as more renewable energy comes online. That’s the conclusion of a new study on the environmental effects of
