The Myth
The "AI is destroying the climate" framing often quotes worst-case projections and ignores rapid efficiency gains. Inference costs per token have dropped roughly 10-fold each year for several years. Major hyperscalers (Microsoft, Google, Amazon) have committed billions to nuclear, geothermal, and renewable power purchase agreements specifically for AI workloads.

The Reality
Data center electricity demand IS growing fast — the IEA projects ~3-4× growth by 2030 in the most aggressive scenarios. Cooling water draws are non-trivial in water-stressed regions. The grid has not kept pace with hyperscaler buildout in some markets. These are legitimate environmental considerations, not paranoia.
The Positive Path
AI is also one of the most powerful tools we have for the *energy transition itself*: optimizing grid operations, designing better batteries and solar cells, accelerating materials science, and forecasting renewable generation. DeepMind's grid-cooling work cut Google's data center cooling energy by 40%. The bet that "AI helps decarbonize faster than it consumes" is plausible — but only if we measure and act on both sides.
