If you are doing it to save money, that's one thing. If you think
you are saving the planet, you've been hoodwinked.

One does not exclde the other. Do not demean the "rush" of realizing
you're doing something "good" grin.


Ahh, the Church of Global warming. Repentance, penance, and absolution
(carbon credits). I get it


All in my opinion, of course! And I do leave my computers on too
much grin.


One of the biggest wasters of resources is the idiotic "sleep mode"
on copiers and printers at places of business. It takes on the order
of minutes for those things to wake up while the person using them has
to wait. When you compute the cost of the person's time vs. the
electricity savings, the electricity savings pale in comparison.
That's a real drag on productivity and output

That's true for a gadget that is used every few minutes, or at least
every half hour on a 24/7 basis. I was more thinking of the TV being
really on while everyone is asleep or at work. Or the copier is on
during the long weekend.

Over weekends and at night I'll buy.


(Our copier at work goes into deep sleep when
not used in an hour or so, so then it is less of a factor).

... and that's where the problem lies. One hour, two hours, during the
business day -- that is what is really expensive. Even if the copier takes
1 kW (not true, but I don't have the numbers to hand) in idle mode -- that
is at most 20 cents worth of electricity (50 cents in California probably).
OTOH, the employee waiting for that copier to wake up from deep sleep --
typically 3 to 5 minutes can easily cost on the order of $3 to $5 worth of
time once you figure labor and overhead into the time accounting for that
person. It becomes even more expensive when the copies are critical for
some last-minute deadline and one has to wait for the copier to "wake up"
because it was idle for more than an hour.
