How Much Electricity Does a PC Use?
was brought up as a question in my household today. How much
electricity does your computer(s) take up? My answer was a somewhat
uncertain, “ummm…not much…”
As usual Google beaconed and I happened onto

is taking up at it’s various stages of operation. The author of the website explains in painstaking detail the different measurements with statements like:
“Add another 80 watts for a 17″ CRT monitor, or 35 for an LCD monitor.

minutes later, the screen went down. The new power management is in
The website that I found has other questions
that are addressed about laptops, people talking business with multiple
computers and even dispels a few myths. The old “Turning my PC on takes
more energy than leaving it on” is gone.
Tell someone about PC power management, turn it off when you’re not using it and let’s save some energy.
