Just look for the blue Energy Star
seal of approval on the printer or check out this list of approved office equipment
If you're interested in electronics that are frugal with energy and friendly to the ecosystem
in other ways, see if your printer is stamped with the Canadian Environmental Choice EcoLogo
. And Swedish company TCO provides a searchable database on its site
of printers, monitors, mobile phones, and computers that meet stringent European Union requirements (see the "Search certified products" button). To make this list, products must skimp on energy, be recyclable, and be free of toxic chemicals. The ultracautious TCO even measures the magnetic and electrical fields emitted by printers.
But no matter which machines are humming in your office or den, the burden of not hogging energy
lies in your hands. Turn off equipment at work when you leave the office overnight and on weekends. Get in the habit of plugging gadgets into a power strip with an on/off switch that you can flip at the end of the day. Leaving electronics plugged into the wall, even when not in use, can drain surprising amounts of standby energy
. For example, a constantly plugged-in printer could add up to as much as $80 per year.
