Free Widgets for your PC can Save Energy

24 September 2009 One Comment

Technology.am (Sept. 24, 2009) — A little software gadget developed by Hewlett-Packard as part of a campaign called Power to Change.

Hewlett-PackardSince June, HP has offered free downloads of its energy widget from its Web site. The small program runs on a desktop and a pop-up encourages users to turn off their computers when the computers are idle for long stretches of time. It also tells them how much energy they’ve saved collectively, as reported by users in regular updates.

HP looks for four-hour blocks when a computer is turned off, and assumes the average hourly energy consumption of a desktop and laptop computer are 67.3 watt hours and 28.1 watt hours, respectively.

The company uses a complex formula to estimate that people using the widget have saved 54,231 kilowatt hours, the energy equivalent of taking 2,169 cars off the road, although Greenpeace says more reliable metrics are needed before these energy savings can be confirmed.

Microsoft has built 30 new power-saving features into its new Windows 7 software. “Probably the most important thing we did is we made power management ‘On’ by default,” explained Francois Ajenstat, Microsoft’s director of environmental sustainability. Vista is also shipped that way. Windows XP, which is still widely used, is shipped with power management set to “Off.”
