A user compared the energy efficiency of AI versus humans: assuming Fable's output cost is $50/m tokens, with 75% margins the real cost is $12.5/m. Estimating 25% of that as electricity ($3.13), at $0.10/kWh this equals 31 kWh. Humans consume 100W, so 31 kWh represents about 310 human-hours of energy, during which the AI produced 500k words.
