So long as it is for a short time (the split is "virtual") then the energy doesn't matter. We are allowed to borrow huge amounts of energy from the void for very short times.
If what is created really is a separate universe, such that there's no communication after the split, we're also okay. "Energy" is really measured relatively - so, if you can't have relations, the other thing effectively has zero energy.
If you can communicate between the branches after the split, you have to worry about the energy exchange between the two. But then, it isn't that you've created a new universe, but you've extended the one you previously had, and for technical reasons that really doesn't satisfy Many Worlds.
