A Tesla Model 3, the most efficient EV, uses 240 Wh/mile. You could not drive more than 8.3 miles without exceeding the 2 kWh/h.

Almost as if hauling 2 tonnes of metal and batteries to transport a single 70kg person is inefficient as hell no matter the energy source...

[sokoloff → restore_creole_]

You get all day to average 2kW, or 48kWh/day, or 200 miles/day [if you spent no other energy, of course].

If you drove 20 miles, that’s 10% of your energy budget for the day, even if you did it all in a single hour.

Might as well just use a horse and buggy at that point.

Personally I prefer a bicycle if the use case and distance is right!

[mrtksn → restore_creole_]

If it was possible to move multiple persons with electric vehicles and if those people lived in close proximity that don't require driving long distances everyday then just going to the shop wouldn't exceed the goal.

[neon_electro → mrtksn]

Sounds logical to me! Put more people in the car and the total energy budget for car travel goes up, right?

[mrtksn → neon_electro]

The budget goes up linearly by person but the cost behaves differently because you don't have to add the same amount of gear for each person.

[tecleandor → restore_creole_]

Well, it depends on the length of the measurement. If you build up the calculation for the total consumption for a year, then you can do spikes of energy use.

[realreality → restore_creole_]

And if you factor in the embodied energy from building the car, you wouldn't be able to drive it, at all.
