My PC consumes 20W when used normally.
AMD Sempron 3400+, RAM: 1.5G, 2 hard drives, GeForce 7300 SE.
It runs GNOME with metacity (no OpenGl effects). The screensaver is a black screen (no OpenGl).
It tops at 80W when playing 3D games.
The screen consumes 25W: 19' iiyama.
It beats your MacBook. My guess is that Macs are bad at energy saving, because they use the hardware accelerated effects to display the desktop. Is that right?

One thing I have noticed is that the computer consumes energy when doing computing. These days, the graphic card is more powerful than the processor. It's the unit that consumes the most power. It dwarfs all the rest. Getting green hard drive is useless when you waste 80% of your energy in the graphics card. The hard drive's consumption is not significant.
