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.
Coal power plant efficiency is less than 40%. You’d also not get 90% of the outlet on the wheels. There is also a lot of loss on the grid, but there is also on the production of fuel. The two pollute almost the same.
Burning coal however is a lot worse for the air quality.
It’s the put the pollution somewhere else policy so that cities are more liveable. It was hurting China’s reputation and too many rich Chinese were going overseas and siphoning away the economy (and still are).
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.
