Key context: thermodynamics dictates that heat engines waste a lot of energy.

The meme only mentions the efficiency of the vehicle so it'd be unfair and in bad faith to compare it to to electric infrastructure and assume it also comes from fossil fuels.
How much energy is spent in mining, refining fossil fuels, transporting it and distributing to gas stations? Crunch these numbers before starting to compare it to electric grid.
