What about quality of life per watt and just making having a certain standard of living more energy efficient?

Simple examples: energy efficient lights seem to have no downsides, better insulation helps my apartment building retain heat, more efficient electronics mean that my homelab servers pull like 100 W total and public transport probably removes a bunch of cars from the road and increases air quality and decreases traffic jams (I can get everywhere I need that way, there’s literally train, tram and bus stops like 5-15 minutes away).
