Funny this post came up, I was using my Kill-A-Watt yesterday to compare my new computer to my old one and 1 power supply compared to another (for efficiency).

Like you said, I think if more people did this energy usage would go down. I know I used to leave my computers on 24/7 now I turn them off every night. It's not that the extra 10/month is a lot but I`m all about saving money wherever I can!

What sucks the most for me is even turned off most appliances still use 2-5 watts. Multiple that by a bunch of appliances and you are probably paying 1-3$ more a month, again not a lot but sucks for something you are not using.
