You don’t want your computer to cheat you out of six microwave dinners do you?
The trouble with some computers is that they consume forty times more electricity than others! Desktop PCs which are usually plugged in all day are ravenous electicity consumers. Unless you take the plug of the computer off the wall, it will still be consuming power even if you think it is off!
If you leave your computer monitor on all night you will waste enough electricity to microwave six dinners!
A PC left running 24 hours per day would create 716 kg of carbon dioxide emissions a year! So unplug it when not in use. Turn off the scanner, monitor, printer, broadband box and audio speakers!
