In this context, I like to think of the Kardashev scale. Humans should be at 0.73, maybe less.

Our natural resources are limited, our consumption and development are endless...

Where does your “should” come from? To my understanding, that’s very close to the current level[1]. So are you saying “here but no further” (and if so, why here rather that, say, 1980 levels?). What would be your preconditions for significantly higher energy usage?
