Per IPCC AR6 total power goes from 18TW to 16TW in a good scenario, due to increased efficiency (no Carnot cycle).
Degrowth per IPCC / earth system scientists mean the 10% the richest consuming less power.
It’s much more a wealth distribution problem rather than a technological one. Both IPCC and IPBES agree there.
Can’t wait for the downvotes on that one. That’s the one hill I’ll die on, literally.
Edit: AR6 (WG2+3)
