I mean, what's your timescale for this "population boom"? Population growth hasn't been speeding up for a very long time (indeed, the opposite). Clearly we use more energy than we need, but I think lots of people hugely overestimate how much room there is to cut that without many many people dying. A very large amount of humanity's energy usage goes toward the food and other infrastructure of civilization that keeps people alive. Improving energy efficiency is certainly one component of decarbonization. But to my knowledge, nobody suggests it is enough on its own, or even a particularly large portion of the mix of solutions.
