>The electrical equivalent of fueling a single Boeing 747 with 65,000 gallons of JET-A in under an hour is ludicrous

You're forgetting that internal combustion engines waste most of the energy in fuel as heat. Car/truck engines are about 35% efficient at the best. I'm not sure what it is for airplanes, but turbines are well-known to be horribly inefficient, much much worse than piston engines; they're only used in airplanes because the power-to-weight ratio is so much better.
