Energy Saving Tips

Computers, monitors and printers all use a lot of electricity. What can you do to reduce energy use and reduce the carbon emissions that cause global warming?

  • Purchase Energy Star computers, monitors, printers, fax machines and copiers.
  • Buy flat screen monitors, they use less than half the energy of older CRT monitors.
  • Laptops tend to use half the energy of a desktop computer. 
  • Purchase recycled paper for your printers and copiers.
  • Set up your printers to do double-sided (duplex) printing by default.
  • Shut down your computer, monitor, and personal printer or place them in a standby mode when you leave the office. Standby and sleep mode cut power use to almost zero.
  • You can do this automatically by using the Power Options or Power Management Control Panel. Configure your monitor to turn off after 20 minutes of inactivity, your hard drive to turn off after 30 minutes of inactivity, and your desktop computer or laptop to go into a standby or sleep mode after 60 minutes of inactivity. You can still access your computer remotely by using Wake on LAN
  • Don't use screensavers, they continue to use the monitor at full power and do not conserve energy. In fact, more often than not, a screen saver not only will draw power for the monitor, but also will keep the CPU from shutting down.

We can all make a difference by carefully managing the equipment under our control. Click here for more energy saving tips for your office from UC Davis.
