The computer you're reading this on may not seem like a huge energy waster, but the power consumption adds up when joined by the other PCs worldwide (Stamford, Conn., research firm Gartner estimates there are more than one billion). A study released last week puts a finer point on this assertion, reporting that U.S. workers waste $2.8 billion annually in energy costs by failing to shut off their PCs at the end of the work day. What's more, machines left on during off hours may emit up to 20 million tons of carbon dioxide (CO2) this year alone, roughly the equivalent impact of four million cars.
The 2009 PC Energy Report, (conducted by Harris Interactive and commissioned by London-based energy-management software maker 1E Ltd and the Alliance to Save Energy, a Washington, D.C., coalition of business, government and environmental organizations) says that nearly half of U.S. workers leave their PCs running overnight. Among reasons cited, according to the report: it takes too long to shut them down, people forget to turn them off or they deliberately leave them on so they can receive software updates overnight.

Peruse Facebook and you'll find dozens of applications to add to your profile that encourage environmental and energy conservation. Many offer obvious advice ("use LED bulbs"), but a new app offers to green up the PCs Facebook members rely on to access the social networking site.
"Green Your PC," developed by support.com, whose parent company is Redwood City, Calif.-based SupportSoft, Inc., offers to help configure settings including your computer's monitor timeout, disk timeout and standby mode so that they comply with Energy Star and Carbonfund.org recommendations. Users can do this either by downloading a piece of support.com software (an .exe file) that automatically performs the configurations or by following a tutorial written by support.com that instructs users on how to change their PC's configurations themselves.
