That is the amount of energy in 0.4 gallon of gasoline. (And yes, there are unaccounted for inefficiencies in both the gasoline and battery charging/discharging, etc.) The situation was worse in 1930 because the volume & weight of 1930 batteries for 16KWH of energy was much greater than with today's batteries.
