pc.jpgThe Alliance to Save Energy has a new report with interesting findings:

  • Out of 104 million office PCs in the US, at least 31.2 million are left on all night.
  • Turning off every work computer in the United States every night would save as much CO2 emissions as taking every car in the state of Maryland off the road.
  • The simple step of shutting computers down each night can save a 10,000 PC enterprise more than $165,000 a year in energy costs. Across the US, this adds up to more than $1.72 billion dollars and almost 15 million tons of CO2 emissions.

Turning off home PCs would also save a lot of money and energy.

One last point: Screensavers waste energy (and modern screens don’t need them).

One Response to A Lot of PC Energy is Wasted

  1. Paul says:

    One would think businesses should be especially vigilant about turning off their computers if only for the dollar savings. Most people don’t realize their TVs and stereos use energy when “off” because of the instant on feature and are better unplugged when not in use.
