Most quality of life improvements do take energy, and yes, quality of life is subjective, it is conceivable to imagine a mind that takes joy in their child dieing of a preventable disease, some vertebrates eat their young, but overwhelmingly, humans like to see their child get old enough to play and talk as well as laugh and cry.

Things like reliable and easy access to clean water, refrigeration for medicine and food, shelter against the weather, clothing, cleaning mechanisms for the above, all of these are non-equilibrium phenomena and so take energy.

So we either need more sources of power or fewer people. I'm glad that birth rates are falling, but lots of people don't have those basic technological tools, so energy technology will need to be rolled out or our definition of empathy will need to change to allow for lots of people to suffer.

While one would agree with your list of desirable non-equilibrium phenomena, the need for more power or less people is non con-sequitur, as you fail to show how the listed things require more energy than our current world consumption.

AFAIK, more than enough food and clothing for all people is currently produced, shelter and cleaning probably isn't far, refrigeration for medicine and required food wouldn't take much of industrial output and problems with access to clean water is often caused by "progress" and could be solved with more strategy rather than energy.

Either way, I think most of current energy consumption is for things like heating / cooling inefficient homes, manufacturing things people don't really need, inefficient transportation, brain-dead things like making oil from tar sands etc.
