I just saw today a nice demo of the power consumption of laptop, desktop PC and a mobile device. Of course I knew that laptop beats PC hands down, but this made it really concrete.
Additionally, the comparison to a mobile device gets one thinking how we could drive this even much, much further!

Being energy efficient is increasingly creeping into offices too.
ITworld cites that flat panel displays consume 67-75 % less energy than old bulky CRT monitors. I assume that nobody is really buying CRTs anymore, so it's perhaps more interesting question how to further save energy in using flat displays. For example, will screen savers actually save energy? The Green computing guide by University of Colorado reminds that "if screen saver images appear on your monitor for more than 5 minutes, you are wasting energy". So adjust your screens to go to sleep after 20 min of inactivity.
