Even if EVs are 100% powered by coal-generated electricity, the efficiency gains are massive, both at the generation end and the consumption end. EVs have up to double the efficiency in terms of power delivered to the wheels, and coal generation units are highly tuned and scaled to extract power as efficiently as possible. Even units balling straight out of the 70s thrash vehicle engines in terms of efficiency. You do lose some electricity due to transmission loss, but even the leakiest of grids aren't enough to cause coal power to be less efficient per joule of fuel than vehicle engines. This ultimately means that EVs contribute far less greenhouse gases than ICEVs, even when all electricity comes from coal.
