David Deutsch writes something about that. 

"Now, there isn't really a story to tell about what the total energy in individual universes is during that whole process [of measurement]. Because the universes are not autonomous during it. But one thing's for sure, there is no way of construing it so that the energy in each particular universe is conserved, for the simple reason that the whole system starts out the same on each run of the experiment (before the non-sharp state is created), and ends up different". --David Deutsch 

"In more general cases, where there are superpositions of states of different energy, energy can increase in one universe at the cost of decreasing in another." --David Deutsch
