> "Data centers are ridiculously efficient. The latest generation of data centers from the big cloud providers have PUE in 1.07 territory, which would've seemed like pie-in-the-sky ludicrousness even 10 years ago. Every CPU cycle that's done in a data center instead of on someone's client machine or on-prem server is a decrease in power consumption."

Those PUE statistics are self reported and aren't very accurate. I've seen them done and they are more marketing/PR fluff than actual conditions of energy conversion efficiency. Nobody in the actual field treats them as being accurate.
