The looming copper shortage does not just coming for EV's. ICE vehicles use a substantial amount of copper (and other metals). "Starters, generators, and alternators contain an average of 2.8, 2.6, and 1.5 pounds of copper, respectively. Alternators also contain 3 to 4 pounds of aluminum. Most of the remaining metal is iron. About one-half of the starters have a solenoid that contains 0.5 pounds of copper." [0]. So that's at least 4.3 lbs (1.95 kg) of copper per ICE vehicle, not including uses in electronics etc.
Correct. The article mentions that EV use 2.5 times the amount of copper though. It also mentions how it's more than just what's in the car - that more copper infrastructure is required to power them. Lastly, it also mentions how using aluminium as a substitute just moves the goal posts, bc more bauxite need to be mined and smeltered.
