According to https://www.theverge.com/24066646/ai-electricity-energy-watts-generative-consumption https://www.theverge.com/24066646/ai-electricity-energy-watt... a reasonable estimate is half a percent of global energy usage by 2027. On the one hand, this is a lot of energy. On the other, that's in the same general neighborhood as what we could save by maintaining proper tire pressure on our cars.
