Peak Petrol

[Deesse23]

Please provide your calculation/estimation.

coal emits roughly 220 lbs of CO2 per MMBTU,   motor grade gasoline emits about 150 lbs per MMBTU.  typical modern coal plants are about 40% thermal efficiency at bus bar, which means roughly 550 lbs of CO2 per MMBTU equivalent of energy delivered to the grid.    Typical road legal car drive train are about 30% thermal efficient, which means about 450 lbs of CO2 per MMBTU equivalent of kenetic energy delivered to the wheel. 

This is without considering transmission, distribution and battery charging loss, which amounts to more than 15%

You forgot the losses due to mining, processing and transportation of gasoline (otherwise its coal apples vs gasoline oranges). The overall efficiency of gasoline is ca. 20% from the oil field until the rubber hits the road. I guess coal is having an edge transportation wise, because of the "bundling" of transportation to the power plants.
Otoh, electric motors have an efficiency <100% which also should be factored in.
Fuel for gasoline engines also has to be on board of the vehicle driven. Same problem Rockets have according to the rocket equation. However the weight of the fuel vs vehicle is rather small.
If you look at the typical driving profile, electric motors have some advantage. They provide good power and efficiency even at low power. Gasoline engines are terrible at low RPM. I would suspect that with a city-like profile, electric motors have an edge. On highways....idk.

The reality, overall, is probably more complex than we know, hence so many opinions.

What bugs me much more than the gasoline vs elektro discussion is this: How heavy is the typical car today, compared to .....30y ago? Weight eats up energy, and ultimately is the main contributor of co2 emissons. Todays cars are incredibly fat (*cough* SUVs *cough*) compared to what we had and i am having serious doubts if everything we have (particularly in terms of ECUs, and copper-wiring) in our modern cars is really necessary.
