Kind of a stretch to suggest that an internal combustion vehicle requires 3x more "energy" to move it than an equally physics-burdened (weight, friction, etc) electric vehicle...

This is only "true" if the energy stored in the vehicle's battery got there without any relevant conversion inefficiency; If those joules came from a gas-fired plant, overall efficiency is only about 35-40%: comparable to a typical internal combustion powered-automobile or actually worse than a diesel automobile.

The upstream energy costs of supplying fossil fuels can also be counted. They add about 1/4 or 1/5th of the total in what are called "Well to wheel comparison". The comparison in the article is "tank to wheel'

It's not a direct analogue to energy but CO2 emissions per km are roughly 4 times lower for an EV charged on the EU grid in 2025, well to wheel.
