I would expect that to be true. Not the best numbers, but Wikipedia puts coal power plants at 37% efficiency and combustion engines at 20-35%. This makes sense

I would expect that to be true. Not the best numbers, but Wikipedia puts coal power plants at 37% efficiency and combustion engines at 20-35%. This makes sense too, power plants have space, money, and an incentive to increase efficiency. And in reality, no power mix is 100% coal, increasing the overall efficiency to above 37%.

- ClumsyPilot 5y agoDoes petrol just appear at the station ready for use? Less than half of crude oil makes it into your car. It travels thousands of miles from the well to refinery, where a chunk of it is burnt to power fractional distillation and separate out Sulphur, impurities, bitumen, kerosene and other stuff that would ruin your car. It's burnt to power catalytic cracking, to convert heavier compounds into something combustion engines can burn. Obviously t is consumed in engines of trucks and ships to deliver it to a petrol station.
