Microsoft announced Wednesday that people looking to save energy and reduce the environmental impact of their computer should turn off their screensavers. A PC running a screensaver consumes more energy than an idling PC in sleep or hibernating mode, according to a statement from Dean DeWhitt, the director of Microsoft's Windows Kernel team. In fact, the screensaver-running PC consumes the same amount of electricity as a 100-watt light bulb left on around the clock for one year. That is about $80 in power that releases about 1,350 pounds of carbon dioxide emissions into the atmosphere, according to Microsoft.
