Suppose all vehicles were a certain type, how much energy would be needed worldwide?

Vehicle type	Powering the vehicles	Manufacturing the vehicles
Battery electric vehicles	1.08 terawatts	Status quo + 0.15 terawatts
Fuel cell vehicles	2.30 terawatts	unknown
Status quo, for comparison (fossil fuel vehicles, mostly)	3.38 terawatts equivalent fuel energy consumption	unknown

- Wattages are total energy consumption divided by time. Not peak power.

A mix of vehicle types is a likely scenario - so expect the wattage to be somewhere in between.

Rooftop solar could provide more than enough energy for this, but only if there's a solution to solar/challenge 1.

The numbers come from: Calc:If all vehicles were electric
