>I think the demand for energy will grow with the supply, as it has for us. I think if we apply what is happening on Earth that is not going to be true. It seems as though per-capita energy consumption increases to a certain point, and then stops. In the US it peaked in the 1970s and has fallen such that even with the intervening population increases US energy demand has barely increased. Depending on who is counting energy consumption (this is all sources of energy not just utility electricity) either peaked or plateaued in 2017-2018. In the US, EU, and Japan energy consumption is decreasing (and it is decreasing faster than population loss in Japan). There are a number of reasons for this but mostly it's efficiency improvements-- which still count! I think there is only so much consumption that a TYPICAL human being can do. Only so much heating and cooling, only so much travel, only so many hot showers. Everyone gets to that point, and then stops. They don't reach that level and start setting up tesla coils for funsies. Once they reach that apex, efficiency improvements start to decrease overall consumption. If population predictions pan out and a shift to more efficient energy production and storage techniques continue, I'm willing to bet that in a century the world will be using less energy than it is today. Same thing for hyper-dimensional interstellar megagods. There are only so many 100km x 100km x 100km cubes of atomically-pure gold one needs in their collection.
