Hi Alvaro, all,
Agree.
We used to have a problem statement for what we called at that time
PANET (Power-Aware NETworking):
https://tools.ietf.org/html/draft-zhang-panet-problem-statement-03
The questions raised in Section 4 of that draft are still interesting
ones (including the potential implications on network operations).
FWIW, other I-Ds were edited at that time. I can cite for example:
* draft-zhang-panet-use-cases: Use Cases for Power-Aware Networks
* draft-dong-panet-requirement: Requirements for Power Aware Network
* draft-mjsraman-panet-bgp-power-path: Reducing Power Consumption using
BGP path selection
* draft-mjsraman-panet-intra-as-psp-te-leak: Building power shortest
inter-Area TE LSPs using pre-computed paths
Some of the documents were already presented in rtgwg and eman wgs. The
outcome of these discussion at that time is that this is more a research
area.
Additionally,
We wrote and implemented an I-D about IPv6 vs IPv4 consumption in
smartphone:
https://tools.ietf.org/html/draft-petrescu-v6ops-ipv6-power-ipv4-00
We wrote, implemented and protected an I-D about an Energy Metric for
IPv6 links:
https://www.researchgate.net/publication/281272590_Energy_Metric_for_IPv6_Links
(this was also an experiment of IPRing an Internet Draft without
publishing it at IETF)
Alex
Cheers,

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.
