My estimate is there are 100 million servers in use worldwide, with
only about 1% of them on a continuously busy duty cycle and most of
them not in the cloud.

If we guess that we save 10W when idle, then that saves some proportion of a GW.

It's not a huge contribution to the effort, but if by doing this we
inspire others to do the same, we may yet make a difference.
