Maybe not stupid under some definitions, but a waste of power for
sure. When I leave my house, I hibernate my computer; that way I can
even unplug the regulator where everything is connected, so not even
standby energy is wasted. When I'm in my house but not on the
computer, I suspend it.

When I turn it on from being hibernated, it takes about 10 seconds to
get to my full desktop. When I wake it up from suspension, it takes
less than 2 seconds. When it is suspended, it wastes 5 watts (instead
of 4 when it's turned off, but connected to the power grid), according
to:

Of course it would be more comfortable to just leave it on all the
time. It would also be more comfortable to not separate organic and
inorganic waste.

Oh, and by the way, what kind of light bulbs do you use that waste as
much power as your PC? Mine uses 15 watts; it's one of the new CFLs:

http://en.wikipedia.org/wiki/Compact_fluorescent_lamp

It is more expensive, and it's a pain to dispose it; but it gives the
same light that a 75 watts normal light bulb, and it pays itself on
electric bills only. Also, it will last longer.

When I moved in with my GF, her electric bill shoot up to the roof (I
brought my 46" LCD TV, PlayStation 3, and in total 5 computers and
other electronics). After a couple of months of shock of seeing the
electric bills, we started to do this kind of stuff
(suspending/hibernating our machines, using CFL instead of normal
light bulbs, etc.), and we cut the spending almost in four.

It is a *little* inconvenience (waiting a few seconds for the TV, the
PS3 or the PC to wake up), but huge money savings.

THAT is certainly not stupid.

Regards.
