While the total energy/megabit might have improved, in general,
devices are eating more
energy than they were a decade back, I used to be able to run
wireless-n at well below 2w,
and more recent devices are well past 8-12w, admittedly able to push
10x more traffic. Idle numbers, I haven't looked at in a while.

Secondly, it seems to take at least 3, maybe closer to 7, for each new
2 year advance in technology
for the software to catch up. I have (formerly) cerowrt (now openwrt)
boxes in the field that have
been mounted on poles and even trees, for over 10 years, just with
steady software upgrades, and
no real demand for more bandwidth - 150Mbits, with good queuing, remains enough.

so factoring in labor, unreliability, security, makes that proposal
pretty green, IMHO. Plus I don't have figures on the costs of spilling
all those electronics into the ground. The power supplies alone...

To me - "energy saving" is mostly industry code for "more unfixible
offloads from the main cpu", and an EE employment act. Vastly prefer
simple, open source, code and a bare minimum of those crippling
offloads, with enough (power saving) cores, much more is feasible.

IF we engineered stuff for a 8-15 year field life, and got off this 2
upgrade cycle it would be a better world.
