"Sleep" spins down hard disks, darkens the monitor, does everything
possible to cut energy use short of turning the machine off. The
machine can recover from this state quite quickly.

Hibernation involves writing the contents of RAM and Video memory to a
disk file, then turning the machine off. No energy at all is used in
hibernation, since the machine is dead. When you boot your machine, it
looks for a hibernation file on the disk. If it finds one, then it
uses it to reinstate your previous session. If not, then it boots
normally.
