What is so energy consuming around fabs? The light source? I always thought of these as high-precision, not-too-high-volume processes and would have expected energy requirements to be lower than e.g. a car factory (or similar to e.g. a mall) and completely negligible on a national grid scale or compared to something like a smelter or lignite mine.
Edit: AI claims HVAC and air filtering/handling can be 40-50% of energy usage. Plus a megawatt per EUV scanner (ok, the latter matches what I would have guessed, but compared to the 16 MW of a single large bucket wheel excavator or estimates I've seen for large shopping malls, that's not that insane either).
