Turn Off the Computer Screen to Combat Global Warming

Turn off your monitor screen manually when you are not using your computer for 15 minutes or longer

» Turn off your computer at night and when you are not using it for several hours. The same also applies to copiers, scanners, printers and fax machines.
One computer left on 24 hours a day will cost you $115 - 160 in electricity costs a year and dump 1,500 pounds of CO2 into the atmosphere.

A tree absorbs between 3-15 lbs of CO2 each year. That means that 100-500 trees would be needed to offset the yearly emissions of one computer left on all the time.
» If you buy a new computer, consider a laptop. Laptops use only 1/4 the energy.

» If you buy a new computer monitor for the desktop, consider a flat screen instead of a CRT monitor. LCD monitors use only 1/3 the energy.

» Enable the Power Management feature for your monitor.
