AI's energy bill isn’t just watts; it’s the future of our power system and choices.
Training a single modern AI model can consume as much electricity as a small city uses in a day.
Idle AI systems burn more energy than global coal burn in transportation due to ubiquitous servers running 24/7.
Strategies like sparse models can cut training energy by over 90% without performance loss in some tasks.
The carbon payoff of AI improves when models retire gracefully, reusing hardware for longer training runs instead of new deployments.
