As part of Earth Hour in Sydney & the fight against Global Warming, WWF have created a useful screensaver that counts the Kw a computer monitor uses when left on and asks the user to turn it off if it's not being used. Visit http://www.usefulscreensaver.com.au for more details and to download the screensaver for PC/MAC. Ask your work IT dept if they can install it on your work pcs & try it out at home - every little bit helps!
