I don't have the figures, but it is quite obvious that infrared uses a lot more power, because it requires a source of infrared radiation powered by the Palm. Serial connection, on the other hand, requires very little power, just enough to open or shut a tiny CMOS gate. I would guess that the difference between the two is orders of magnitude.

This is, of course, for transmission. There is only a negligible amount of power used for reception, in either case. Thus, infrared wireless Palm keyboard should not be any more taxing (on the Palm) than the wired one.
