Microsoft has today attempted to counter criticism that its new Windows operating system represents a power-hungry ” environmental disaster” with the launch of new research that suggests the system’s new power management functionality could slash the energy demands of PCs and notebooks.

The study from PC Pro Labs compared the energy usage of Windows Vista and Windows XP based on “real world” workplace usage patterns and found that systems running Vista would use up to £46 less energy over the course of a year. It claimed that this is equivalent to a saving in CO2 emissions of 45 tonnes for a business running 200 PCs.

The savings were calculated based on a survey of 800 visitors to PC Pro’s website which found that users’ PCs typically spend 40 percent of the time undertaking “light tasks”, a further 30 percent sitting idle, and 30 percent doing medium or very intensive tasks such as photo editing or encoding. The survey also found that almost a third of users leave their PC on overnight and a quarter leave it on over the weekend.

Very cool, and an interesting article. It raises some interesting points about Vista, but also highlights how little changes in the way you manage and run your pcs can make a big difference in your energy consumption (particularly in large sites), for example, switching that screensaver to a blank screen, enabling sleep/hybernation mode, check it out.
