## Quote — verbatim

> Each prompt, each call takes about 2.9 watt hours... 2025 we're going to need about half a gigawatt capacity to serve AI... and every year it's growing at 37% — the energy needs for AI, that includes inference and training.

## Context — site annotation, not spoken

His "mid-conservative" published model: ~1B AI users today doing ~5 inference calls/day, growing (on mobile/internet-like adoption curves) to ~150 calls/day by 2040.
