An ICE is only, at most, 35% efficient. In contrast to lithium batteries and electric motors, which is more like 90% efficient. Electricity produced from the dirtiest coal plants that exist, used in an EV, is more efficient and, thus, more environmentally conscious, than burning gasoline in an ICE.
What about the billions of cells that must be produced and replaced as the scale grown unto millions and millions of cars? And all the mining of rare earth elements it requires?
It turns out that the lithium is very recyclable. The process of disassembly is what’s tricky, but one of Tesla’s pre-musk founders is working specifically on this problem.
We can already do it. Mining is (for now) cheaper. Something legislation, applied carefully, can resolve.
I don’t know if their statement is universally true, but the EPA’s fuel economy / total emissions calculator seems to show it for what I’ve put in. You can put in a Prius or random EV and see how they compare.
My guess would be the efficiency of coal power plants (35%) and electricity transmission (90%) + battery charging of an EV (80%) would be more than efficiency of transporting oil in ships (50%) , then in an ICE truck (40%) to fuel pumps and then finally the efficiency of the ICE car (40%).
I picked the numbers from internet, but they seem plausible.
Could you please run us through your maths? I’m legit curious.
