An ENERGY STAR® certified computer uses 25%–40% less energy, on average, than a standard model. Desktops, integrated desktops, notebook (laptop) computers, workstations, small-scale servers, and thin clients are all eligible to earn the ENERGY STAR certification, and those that do are now more efficient than ever. Pair your computer with an ENERGY STAR certified printer to save you even more energy.

Benefits of ENERGY STAR certified computers

  • Efficient internal or external power supplies to ensure energy savings in all modes, including "off".
  • Power management features put your computer into a low-power "sleep" mode after a designated period of inactivity.
  • Those with strong network capability do not lose their network connections when in "sleep" mode, which helps protect against data loss.

How to use your computer efficiently

  • Consider buying a notebook/laptop, which are designed for higher energy efficiency due to their size and portability.
  • Activate "eco" mode to minimize energy use and make your laptop computer battery last longer.
  • Turn off your desktop computer and peripherals (like speakers and your monitor) at the surge protector when you're not using them to save energy wasted by background activity and standby power.
  • Remember, surge protectors often look like power bars, but not all power bars are surge protectors. Only surge protectors will protect your electronics from a power surge.
  • Avoid using a screen saver. A screen saver draws power for the monitor and can keep the computer from shutting down.
