So then in the case of a grid like Californias or say a state with a higher % of hydro, Nuke, and renewables it would be a higher % than with just a single fuel plant- correct?
We know without a doubt the EV is more efficient at converting the energy - so then it becomes a matter of the grid source which isnt fixed.
The net effect over time as the grid sources change and becomes more efficient the car becomes more efficient whereas an ice vehicle has relatively fixed efficiency.
Natural gas would NOT be a best case efficiency.
