How to save power?
2)Monitor Setup - Decrease the brightness will help me in save the power?
Is underutilizd machine is same as if it was running at full capacity?
Any suggestion on power saving?
Yes it does...
Specially with AMD Processors with "Power Now" and "Cool n' Quiet" features, Its also supported under Linux
Decreasing brightness also saves electricity.
Thats why I use Darker Themes.
When Monitor shows "Black" color it uses very low electricity or no electricity.
check this page..Blackle This is Google Search with Black background, saves energy!
ok..i'm agree with reducing monitor brightness will help . (because i think i read some where about this ...)
Have this example:
1) my cpu is running web browser and consumes 15% to 20% of CPU.
2)I'm playing Tremulous which uses 60-80% of CPU
- Is this power consumption is "significantly" different for these two scenarios ?
I read a book which said both are more or less same,that's one reason why virtualization is popular.
The statement was something like this
"In normal CPU utilization is less - consumes about 10-15% and remain 85-90% of CPU is wasted ..but the power consumption of underutilized machine is same as full-utililzed machine " .
Yes, Its true, because energy utilization difference between 10%-90% CPU usage is very low, The amount of power saved is like nothing.
Also with the monitors, The energy usage difference on CRT monitors are high, while on LCD It doesn't make huge difference between bright and dark backlight, but makable change is there.

This rule (When Monitor shows"Black" color it uses very low electricity) isn't true on all types of monitors. For example brighter colors in LCD monitors uses less power than darker. I researched this and result of my work you may find in link bellow.
Sorry for the link but there is too much to write and I don;t want do it again.
