Public bug reported: When running the Ubuntu 3D desktop (with Unity 3D and compiz), my system draws 3W more power when idle than when I run unity2d+metacity. This is a 25% increase in power consumption vs. idle draw with wireless on, and a 33% increase over idle draw with wireless off.
This is all when *idle*, i.e., nothing moving around on the screen... so there's no reason for the graphics chip to be drawing this kind of power because there's no 3d rendering that needs to be done. Must be a bug somewhere.
