Among the main reasons why an EV battery costs $10,000 is because it is so energy intensive to mine the materials and fabricate them into a battery.

As a rule of thumb, things that cost more consumed more energy. I think we can get a close approximation of when the breakeven point on EV vs ICE is simply with total cost of ownership. The year in which an EV has a lower total cost of ownership per mile driven than an ICE is roughly the year in which ICE begins to contribute more CO2.

I gave you the values in #4 (permalink ).
