How does many worlds justify the doubling of energy with each quantum split? Probability can double all the energy in existence for every quantum fluctuation? Is energy conserved between realities? If not, that makes reality a very strange place. We could potentially use that to create infinite energy, infinite people, planets we could grab, if we could move stuff between worlds.

They do it by correctly noting that there's no such doubling. Conservation of energy is within-world, not cross-world.

Is energy even corserved in each world? I think it's conserved in average in the multiverse.

Interesting layperson question, though!
