There seems to be some debate as to whether this is strictly right, but I like the fact that it might be so will run with it anyway!
The basic idea is this - CRT monitors (tho not LCD it seems) use more energy when showing white than black. So what if the pure white Google, the world's most visited website, had a black interface option?
The impact would would be a saving of 750 Megawatt-hours a Year apparently (though I'm not sure what that actually means)
And if you think this makes sense, Blackle now gives you a way to do your bit. Because, thanks to the Google Custom Search facility, they can provide you with a bit of search on the dark side.
With 206,422.190 Watt hours saved in the process so far.
