Which is more energy efficient: completely shutting down the computer at night or not? Please don't give the answer my husband wants!
The answer to your question depends on whether your computer’s sleep mode is activated. Both you and your husband could be right depending on how many hours a day you are at the computer. Setting a typical desktop computer to sleep mode will help save energy if you are away from it at least four hours a day. To maximize your energy savings, turn it off when you know you're finished.
Sleep mode automatically puts your computer and monitor into a low power state if there has been no activity for a period of time. You can choose the number of minutes you are away from the computer before the sleep mode is triggered.
Here’s how the different operating modes stack up:
Not sure how to turn on your computer’s sleep mode? On a PC, you can find the sleep mode by going to Control Panel and selecting Power Settings. On a MAC, use the Options pane and go to energy-saving preferences.
To save even more energy, use a smart power strip for your computer and computer accessories like printers, monitors and speakers. Smart power strips can detect if a computer is in sleep mode and can turn off attached devices when the computer is powered down.
