It's a lot more complicated than how much power a tablet uses while you're on it. There's a lot more energy involved in making one than in making a book. And green means a lot more than just power consumed. Computer circuit boards are known to involve a lot of very message manufacturing processes, and there's the disposal of the worn out ones afterwards. Paper books can be put in a landfill; computer stuff cannot (especially the lithium based batteries).
I've never seen a clear-cut comparsion that I found plausible on the complete life cycle of paper books vs ebook readers. When you factor in the stuff people do on tables vs desktops, or televisions, I doubt such a comparison is even possible.
Interesting point, though.
