And a much more pronounced divide than people realise. Firstly, people don’t realise how much electricity is used just to refine petrol and diesel. Also, only a quarter of the embodied energy in fossil fuels turns the wheels of the vehicle. Most of it is lost as heat and noise so you’re emitting 75% of the CO2 without getting useful work. The transition means using electrical energy far more efficiently than the chemical energy in hydrocarbons.
