Great blog about EV's! I appreciate the context that ALL cars are bad for the environment...it's easy to forget this in our zeal to adopt the latest technology. I just wanted to point out that you didn't mention one of the most important aspects of EV's and that is their potential to stabilize the electric grid by adding storage and to green the grid by unlocking more solar photovoltaic energy generation. The biggest impediment to growth that our grid has now is that we can't really add more solar generation capacity without having the means to store it (know as the "duck back" problem.) Peak electrical demand is around 7 pm when everyone gets home and turns on their appliances but peak solar supply is around solar noon. We just need the means to store (a lot) of solar energy generated from about 9 am to 3 pm and then release it back to the grid during the evening peak demand around 4 pm to 9 pm. A typical EV today has a battery equivalent to about 6 or 7 Tesla Powerwalls and as soon as UL and IEEE write standards for bi-directional car chargers (V2H, V2G), we can have our EV's power our homes (and if our PUC's will allow it, also power the grid).

Awesome information and thank you for putting this together in a one collective article to share! Really helpful!

Kinda relating to a previous HEATED article which mentioned meat and diary companies fighting fossil fuel companies because of competing interests, I'm curious if we will see something similar with car companies as EVs become a higher percentage of the profits of car companies. After all if fossil fuel companies continue doing what they do doesn't that directly affect the ability of car companies to sell EVs?

Also I think it is great to be skeptical of recycling claims but as far as I'm aware, lead acid car battery recycling is a genuinely incredible recycling success story. 99% essentially are recycled. Which makes sense to me because of common act of trade ins, etc. And while lithium car batteries are nowhere near that in terms of recycling, I think that is more to do with just the newness of EVs and lack of a circular trade in economy for it. Seems like IRA provisions should help with EV recycling too.

However that obviously doesn't take away from just the unbelievable amount of new materials needed to reach the goal of essentially replacing gas cars with EVs. Don't want to minimize how much mining and materials will be needed there.
