We can only go through a few more doublings of our current energy production rate before we boil the oceans from a thermodynamic equilibrium standpoint (ignoring greenhouse gases). Earth has a fixed surface area. And the only way to get rid of waste heat from energy production is to radiate it into space. Finding this equilibrium for given quantities of energy generation into waste heat is a pretty straightforward calculation.
