The Floor

0.87

The PUE value Google's fleet would have needed in 2024 to keep electricity flat despite +27% growth. The physical floor of the scale is 1.0.

PUE measures how much electricity a data center burns on top of the actual computing. Perfect would be 1.0 — physics allows nothing less. Google’s fleet sits at 1.09. Sounds nearly finished. It is nearly finished: the scale is almost used up — and this is the number the report holds up as a counterweight to growth.

"Needed" = the PUE that would have kept electricity consumption flat at Google's own growth (+27% in 2024, +37% in 2025) — each derived from the disclosed figures. Everything left of the floor line is thermodynamically unavailable.

The efficiency curve moved 0.01 in six years. Emissions: +120.5%.

Above ten percent growth, the arithmetic demands a value below one. Physics doesn’t do discounts.

2023: 0.94. 2024: 0.87. 2025: 0.80. Every year lands further below the floor.

Google doesn’t hide the growth — the +27% is in its own report. What’s on trial is not the candor but the framing: a floor-bounded ratio, held up as a counterweight to unbounded absolute growth.
