At dinner parties and random conversations, I am frequently asked if EVs are really clean when compared to their gasoline engine counterparts. There seems to be a lot of confusion out there in part generated by the media on how clean EVs really are. The reality is it depends on the how clean your utility is in generating the electricity you are using to fuel your vehicle.
I was excited to see today that The Union of Concerned Scientists has developed a useful and very simple tool that allows you to determine the actual climate impact of your vehicle for any zip code in the United States. Now I have a place to send those that ask me the same question over and over again.
I live in Los Angeles Department of Water and Power (LADWP) territory. LADWP generates a lot of its electricity from coal, but even with coal-source electricity my EV is cleaner than a gasonline powered vehicle.
