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).

> energy efficient lights seem to have no downsides

Efficiency is good, but this isn't true. Decades into LED-ification we still suffer shit-tier PWM strobing, poor dimming, disruption to wildlife and human life, and streetlights turning purple en masse.

(The last two are installation and quality issues, but when driven by lowest-bidder compliance with simplistic "efficiency" mandates that's what you get).

		Lower color rendering index than incandescent lights too. High CRI LEDs are available, but they're still worse than incandescents and less efficient than the conventional LEDs.
