Saving power on your PC is a bit like Mark Twain's saying about the weather: Everyone complains about it, but no one does anything about it.

Here's your chance to do something about it, in a small way. Verdiem just released the free Edison software, that makes it far easier to use the power management features of your PC. With it, you won't have to wade through Windows' confusing menus and options to try and fine-tune power savings. You'll only need to move some sliders, click a few buttons, and you'll be done.

How much you'll save varies according to your system, of course. On mine, Edison said I'd save 359.63 kilowatt hours of electricity a year, which means $32, and 490.17 pounds of CO2.

Keep in mind that this is a personal tool, not an IT tool. Still, for your personal systems, it's worth a try...after all, it's free.
