I will add my opinion on this.

As being discussed in one thread.  Linux is not a boot when required 
OS.  It is designed to be run 24/7 and thus may not be the best OS for 
"saving" money.  On the other hand, it also is useful being on 24/7.

In our house, our computer can be used almost anytime during the day 
or night.  Being on is worth the extra electricity costs.  Of course 
the Satellite receivers, VCR and instant on TV uses power as well. 
The question is how much extra power is the Computer using in whole 

Also, we run SETI at Home using BOINC and will be adding other BOINC 
projects to the mix.  This is one way of providing some usage out of 
our computer when we are not using it.  We do this at work as well.

I prefer CRTC monitors over LCD at present.  Poor Contrast Ratios for 
LCD and time lag are two issues that I don't like about LCD.  I have 
an LCD at work and I would replace it in an instant if I could.

I do hate the energy star monitor that shuts off and I am still trying 
to get it to stay on for a longer period of time.  This is only a 
setting but it is one of those little things that does save energy.

There is always the cost of convenience to look at.  I have logged 
onto the computer for 2 minutes to look up some info and then logged 
off.  How much would the time to wait for booting and then to log on 
be worth to me and other users?
