I was pondering that earlier... I'm wondering how the collective power
consumption (with all those powered ONT's) will look in comparison to a
PSTN/DSL world...

There are some interesting developments in Europe on required standards
for CPE (including ONTs) for low-power and 'green' always-on devices.<br>

"...Fully compliant with the European CoC power consumption levels
(L0/L2/L3), the Velocity chipsets’ power profile is the industry’s
lowest at less than 1 W per port, over 30 percent power savings
compared to the next best A/VDSL chipset offering."<br>
<br>
(yes this is copper, but the Euro Code of Conduct is intended to drive
power usage down in all CPE)<br>

As for replacing batteries and needing technician truck-rolls - meh -
make it user-replaceable, add an audible alarm and flashing light when
the battery gets low, and re-use the distribution (and recycling) chain
for telephone books to throw a new battery onto everyones lawn every 3
years. A small gell-cell would have to be lighter, smaller and more
efficient to distribute than 2 volumes of the Sydney white-pages. <br>
<br>
Maybe a new service provided by your local council - leave your used
battery by the bins for recycling when the rubbish is collected, and
the garbos leave a new one in the morning.<br>
