That's not really "at best" - at best, this represents a mix of new demand plus some compute being moved from customers' on-prem / small and inefficient datacenters. I'm not sure how much of AWS's growth is "new compute" vs "moved compute", but for the part that's moved, it's not necessarily a bad thing for it to move to a datacenter with a low PUE (power utilization effectiveness - overhead such as cooling/backup power/power supply inefficiency) that uses green power. (AWS/Google/Microsoft's datacenters are a _lot_ more efficient on a per-compute basis than the typical small corporate datacenter; like 30+% lower power waste because of inefficient AC and power distribution design.)
