Reaching those PUE numbers is pretty damn impressive though.
I think the misconceptions come from enterprise DC environments with traditional hot/cold aisle designs, servers running way cooler than they need to be and peak power requirements leading to overly expensive power/cooling costs. PUE for these closer to 2.0 than GCE is to 1.0.
If you have something like GCE where you can control for all of those, i.e run the DCs hot, eliminate transient peaks, source power cheaply and use super efficient cooling like evaporative or geothermal pumped water etc then yeah, it's a completely different ballgame.
It's pretty safe to assume all the hyperscalers are doing all of these things too, they aren't stupid. :)
