Electronics Tips

  • Unplug electronic devices when they're not in use. Some electronics, such as televisions, use up to 10 watts of energy when they're off and still plugged in.
  • Unplug devices that use standby power, such as DVD players, video games, printers, scanners and set-top cable boxes.
  • Some video game consoles, when left on continuously, can use the same amount of energy in a year as two new refrigerators
  • Use a power strip to plug in electronics.
  • Purchase ENERGY STAR® home electronics. An ENERGY STAR® television uses 30 percent less power than other models.
  • LCD televisions consume less power than plasma or rear-projection models.
  • When watching high-definition DVDs, use a standalone DVD or Blu-Ray player instead of a video game console, which uses five times the power.

Computer Tips


  • Shut down your computer if you're going to be away 2 hours or more.
  • Plug your computer and peripherals into a power strip and shut them off using its on/off switch.
  • Don't use screen savers. They use more energy. Plus, the newer LCD monitors no longer need them.

If you’re buying a new computer,...

  • Consider a laptop. Laptops use about 90% less energy than a desktop.
  • Look for ENERGY STAR® qualified computers, which must meet efficiency guidelines in three operating modes: active, standby, and sleep. They also have energy efficient power supplies.
  • Purchase combination peripheral equipment, such as a combined printer/scanner, which uses one plug instead of two.
  • Buy a flat screen monitor. It uses less energy and is easier on the eyes.

If you’re keeping your computer,...

  • Increase the RAM. RAM is inexpensive and relatively easy to install.
  • Replace the hard drive. Newer hard drives allow for faster data access - a requirement for newer operating systems.
  • Replace the video card. A new card increases the performance of graphic operations.
