'[OT] Vista and Global Warming'

On the topic of Windows Vista and global warming;

I noticed that when using Vista with Aero and an animated desktop, the CPU
usage went up to a little above 10% constantly when idling, as compared to
below 1% without the animated desktop. I wonder how many (nano-, micro-, milli-
) degrees this increased energy consumption will add to the global warming.

This asumes that:

- The increased CPU usage actually does use more power (the CPU has to do
something anyway, right?)

- Newer computers with Vista uses at least the same amount of power than older
computers without Vista.

- A substantialy amount of newer computers will use Vista as the operating
system and that these users will use an animated desktop.

The difference in power consumption is probably also even higher for the
graphics processor.

This may be a drop in the ocean compared to the increased energy use from other
places; More and more computers, cars, TVs, cellphones... are used every day.
How long will it take until everybody in China, Africa, India... will have one
of the above. Don't get me wrong, I don't mean that they shouldn't but that all
the increased power usage for all these devices (including animated desktops)
has to come from somewhere.

I guess what I mean is that the increased power usage is very small for one
single individual but the sum total, globally, has to be quite significant.

The flip side to this is that Vista supposedly handles the various sleep
modes better, so it uses less power when you leave it switch on overnight.
IIRC, this is because the default setting are set to save more power, unlike
previous versions.  The fact that various manufacturers now make hardware
that does what it's supposed to do might account for that change.

I guess it's a bit much to ask to to re-install XP and run a comparion with
a meter...
