The backlight consumes most of the energy, yes (a well regulated screen brightness -which reduces the backlight intensity- is the best practice); and energy savings with dark colors are especially noticed on CRT screens, where savings can even reach 20-some %, I don't remember exactly; but as far as I remember, when that "blackle" (Google with a totally black background and grey letters) and sites thing appeared, a couple of years ago, coments on some blogs (blogs that seemed reliable, I mean, of course, like Nature's one) said that despite the savings for LCDs were much smaller than those on CRTs still there were small savings, that's why I said dark colors save "some minutes" of my battery.
Anyway, I'm no expert at all; the main reason is just that I can't stand much time with a device throwing a lot of artificial light to my eyes. On this I think every occulist would agree, and if I can also save 3 or 4 minutes, welcome they are.

In few years LED screens will be the usual, and in them pixels are self-, not retro-, illuminated, so I still think it's a good habit for the near future.
