    I am not sure how easy it is to do such an experiment.

You could let your laptop run without AC power, with Emacs running
and without it, and ask acpi what the power drain rate is.

    Given that so many applications wake up so often, what emacs does
    might not be measurable at this point, but it might make a difference
    in the future.

You could try also killing other X apps, and try killing X too.

I just tried some experiments.  Having Emacs running under X does not
increase my power drain rate.  However, having X running (with GNOME)
makes a big increase -- about 50%.
