Intelligent computer use can save energy costs by 75 dollars each year

It has said that simple tasks such as turning the computer completely off if its not to be used for several hours, or setting the power management functions on the computer to put both monitor and the CPU into “sleep” mode after a certain amount of time of non-use, could save energy.

However, care has to be taken that the computer goes into the ’sleep’ mode properly, it said.

Certain applications such as some games and third party software, which run in the background, prevent the computer from going into sleep mode. As such care should be taken to ensure they are completely shut down, the agency said in a statement.

A virtual private network (VPN), if used, should be disconnected when not in use actively, since VPNs can prevent the computer from entering into sleep mode, the statement said.

“Applications such as Wi-Fi antennas and infrared ports, which continually scan can prevent the computer from going into standby mode. Some Web sites will not allow your computer to enter into sleep mode because of active advertisements and banners. Close down all Web pages when you are not viewing them to allow your power management function to work properly,” it said.

“Peripherals, which are plugged into your computer, can also prevent your computer from going into standby or “sleep” mode. Unplug your peripherals when they are not charging or synchronizing. Shut off the printers. They also have a sleep mode that still consumes a significant amount of power,” it added.

The EPA said screensavers also prevented the computer from going into the sleep mode.

It said other things one could do to save energy in computing could include: Increasing the RAM to reduce disk usage; upgrading a CRT desktop monitor to a LCD flat panel monitor, which could account for half the energy; and replacing wireless mice and keyboards with wired counterparts, thus avoiding unnecessary wastage of batteries.

“Reduce what you can; offset what you can’t.’ That’s our motto,” said Steve Offutt, chief operating officer at, a non-profit, non-partisan organization dedicated to supporting renewable energy, energy efficiency and reforestation projects globally. (ANI)
