Hi Lee, There are many ways to quibble over this. The accounting I read estimates the copper that is used in all the ICE currently on the road worldwide, and estimates the total copper in a 100% BEV global fleet to be 5 times greater. During the course of retiring that ICE fleet there would be recycling of copper. I haven't thought super hard about this, but I assume a large part is in the batteries, and the motors have a big load of Cu. Then there would be bus bars,presumed to be copper for lower resistance. EVs have a lot more electronics in them, although that is not the fault of the EV, more the attachment to cameras, bigger computers. and so on. There is electric HVAC.
The total number of Teslas is just under 4M, and the total of all cars is just under 1.5B. That is a factor of 375. All the Teslas are 1/375th of the total number of ICE worldwide. Similar issues will arise with all electronics but mostly because of the failure of the large sources of palladiums (Pt, Ir, Os, etc.),the stuff it takes to make 10nm ICs. Neon for lasers comes from Mariupol where pig iron is no longer made. THere are so many other sources of un-supply that are needed for EVs. Basically the supply chains are going to be hosed for a good minimum of 10 years. The whole green future is hazy at best for 20 or more years. Maybe this is all worst case thinking, and we can do better. Lots of money to be made rearranging the industrial world, but it's not going to be easy at all. Anyway, Toyota may have run some numbers like this and decided they can happily make an enormous number of ICE while a tiny fraction of EVs are made.
