I also think this could be an interesting topic for the IETF.
A few years ago we wrote a "Framework and Requirements for Energy Aware Control Planes” [1]. There wasn’t a lot of interest at the time and we intended to publish it somehow, but got busy on other things…

Along these lines, roughly a decade ago I filed a patent for
selective routing to data centers for purposes of power control and
environmental impact [1]. While I've left Juniper since, if
there were interest, they may be willing to assign the IPR to IETF
if asked nicely.
That said, this patent somewhat missed the claim.
What's really needed is power-based routing in general (not
just to data centers), whereby how green the power is matters.
Of course, getting routers to accurately testify the greeness
of their power source could be difficult...

I think it is an interesting topic and very much on
topic for us to think about. And a topic where potential savings
could be significant. IT is a huge energy consumer (as well as a
producer of short-lived gadgets). IT also has the potential to help
optimise many non-IT processes, and therefore directly reduce
energy consumption and waste.
But of course this is also complex topic and not one where only
IETF or only standards help. And a topic where continuous
improvements in compute and comms are often offset by more high res
videos and ever growing software packages (as well as auto-play and
zillions of adverts, placed on my screen after way too much ML
analysis).
I’d be eager to work on this, assuming we can come up with
proposals that can have an impact.
