gasoline is 100 time more energy dense than electricity, thus even inefficiencies at 70% for IC engines, gasoline would still be more dense somehow. But there is alot of geopolotics and environement issues involved with fuel. The problem of energy density needs to be resolved for electricity so it would be more convenient to use, even at the industrial scale, which is a major carbon emitter.

The issue is that ICs just suck badly. So badly that carrying around half a ton of batteries still makes EVs much more efficent. that is not even looking at how petrol is made, which btw also requires electricity.
