It has skyrocketed because of increasing availability of energy. Energy is a conserved physical quantity. Hydrocarbons are basically a giant magic solar battery that was charged over tens of millions of years. We’re basically charging that down to zero in a few centuries like there’s no tommorow.
It doesn’t take much energy to extract this energy. In the case of solar or nuclear it takes a lot more energy to extract it safely and at scale.
You can read about the EROEI of shale, solar etc vs oil. We have fought against it using efficiency but efficiency too has limits.
If we didn’t discover oil / coal none of these changes you mentioned would have happened.
That there will be constant continuous and infinite improvement on a finite planet is far from clear. We can decline, or even go into stagnation for centuries until some major breakthrough.
There was a time when progress was so quick that people assumed flying cars were around the corner and we would all be living in space like the Jetsons. Again energy costs come into play.
