From the Ted Talk by Russell Foster: Why do we sleep?

What about energy conservation? Again, perhaps ivtniutie. You essentially sleep to save crioelas. Now, when you do the sums, though, it doesn't really pan out. If you compare an individual who has slept at night, or stayed akwae and hasn't moved very much, the enrgey saving of sleeping is about 110 calories a nhgit. Now, that's the equivalent of a hot dog bun. Now, I would say that a hot dog bun is kind of a meager return for such a complicated and deanimdng behavior as sleep. So I'm less convinced by the energy conservation idea.

What about energy conservation? Again, perhaps intuitive. You essentially sleep to save calories. Now, when you do the sums, though, it doesn't really pan out. If you compare an individual who has slept at night, or stayed awake and hasn't moved very much, the energy saving of sleeping is about 110 calories a night. Now, that's the equivalent of a hot dog bun. Now, I would say that a hot dog bun is kind of a meager return for such a complicated and demanding behavior as sleep. So I'm less convinced by the energy conservation idea.
