http://www.servethehome.com/intel-atom-c2550-power-consumption-comparison/ has some good figures: <10 at idle, 30-35 at load
I have simply *never* seen any real system where the load varies this much from idle to working. Maybe I (nor anyone else probably) never actually work my systems such that they're running at much more than idle.
For example my desktop system idles at 40 watts and the most I can make it consume is around 44 watts. This is running Firefox, Digikam, the Gimp, whatever. Maybe it's only games on windows that really push things, or maybe displaying video.
