Holy shit, is that really what a 747 draws? That is nuts. I worked for a few summers at a powerplant that put out about 40-50 MW/h, burning wood biomass.
As a physicist, I'm always surprised how people generally get units right [1], but they shoot themselves in the foot multiple times over when trying to measure power and energy.
MW/h doesn't make any sense. A unit of power would be MW, a unit of energy would be MWh (megawatt times hour, not divided by hour). MW/h would be a power increase over time, which is surely not what the parent means.
[1] Unless they're in the US, Liberia or Myanmar. :)
