Harvard University Green Tip of the Month


March Green Tip

March Green Tip

Devices like televisions, microwaves, scanners, and printers use standby power, even when off. Some chargers continue to pull small amounts of energy, even when plugged in (a good judge of this is if a charger feels warm to the touch).

To avoid paying for these “phantom energy drainers”, use a power strip to turn all devices off at once. Flipping the switch on your power strip has the same effect as unplugging each socket from the wall, preventing phantom energy loss.

Studies have found that phantom energy loads account for 5-10% of the total electricity in residential homes and accounts for about 1% of the world’s carbon dioxide emissions.*

Setting the Record Straight

Many people think that turning something off stops it from using electricity, but many appliances keep consuming energy when they are plugged in but not on.

An easy way to identify products that use standby power is to see if they have a remote control, continuous digital display (like an LED clock on a microwave), use a rechargeable battery, have a soft touch keypad, or have a large block shaped charger.*

Your Actions Add Up!

If 50% of Harvardians who own a printer (assuming 1 in 3) turned them off with a power strip when not in use, we would save approximately:

  • $100,000 in utility bills
  • 0.6 MILLION pounds of CO2 - which is equivalent to taking 54 cars off the road!

and that’s just for printers - imagine if we unplug or use a powerstrip on all of our phantom energy drainers!


Resources

  • Smart powerstrips work best for computers and their peripherals (speakers, monitor, scanner, printer, etc.). When the computer is shut down, the power strip shuts off all of the peripherals. They cost about $40 and can be purchased online.
  • Standby Power: Lawrence Berkeley National Laboratory. Learn more about which appliances (at home and work) use the most standby power.
  • Remind yourself and colleagues to shut off strips at the end of the day with this electronics door prompt
  • Conduct an audit of your office and leave this friendly reminder where phantom energy is being wasted
