"Enable screen savers to save power!"
You must have heard it a lot...but its nothing but a myth with current generation computers.
It takes more power to display graphical images on the screen,especially a CRT monitor.
So,if you want to save power, instead of enabling screen savers,configure your system to put monitor to sleep after a period of time.You can also set system to shutdown after a long period of inactivity if you want to.
Still,if you want to show a screen saver,chose one with minimum white..a complete black screen might save some power.
In Linux,you have many attractive screen savers...many of them on black themes.You may choose one of 'em or choose the first option(Blank Screen).Also remember to set your monitor to sleep after prolonged idle time.This applies to Windows also.
I used to have Linux screen savers with 10 minutes timeout,and I have enabled random screen savers.Now I changed it to Blank Screen with same timeout.Also my monitor goes to sleep after 25 minutes of inactivity.
I boot my system using BIOS RTC at night for scheduled downloading,that too with monitor and speakers off...just the cpu and router remains powered up.After 8.15 if I don't attend to system,it shuts down automatically.
I am mentioning all this,so that if someone in similar cases wants to save power,they can follow my model or use a better one.I have seen many people(even I used to) keeping system on overnight so that downloads can be done later...but most of the motherboards support Booting over RTC...use that to minimize power usage.
Wish all a happy and green computing...signing off...

screen savers were initially made to prevent damage to the crt caused due to prolonged exposure to static images when the monitor has no changes.
This was a problem with old CRT's alone.
They were not made to save power.
