Joules is the solution to both the problems (the second is that Wh for energy is as silly as speed hours for distance)

Watt-hours is a perfectly pragmatic unit. Measure instantaneous power and multiply by a common human unit of time. It's easy to compare.
Part of me is tempted to suggest kilograms as a unit of energy.

428.6 kg relativistic mass-energy equivalent: https://www.wolframalpha.com/input?i=10.7PWh%2F%28c%5E2%29

But then, I am a silly person.

Call the unit "Kilogram-Joules", abbreviate as KgJ and it works pretty damn well and unambiguously.

The problem is we don't live in a society powered by matter-antimatter annihilation reactions, or black evaporation so it's not really useful - unlike say, the electron-volt which at least serves physicists nicely.

This would be a devastating own if a single Joule wasn't exactly equal to a Watt-second.
