My answer covers sleep and hibernation, as well. The sleep mode in Vista and Windows 7 behaves similarly, but more efficiently. Hibernation , in all three versions, saves even more power, although getting into and out of hibernation takes longer. Double-click the word Computer to expand the section under it. You should see something with the acronym ACPI in its name.

See image below, the power options is highlighted and circled in red: Once the Power Options Properties dialog appears, check if there is a tab labelled Hibernate. It should be the last one on the extreme right end of the dialog box. See image below, the hibernate option is circled in red: If you are not able to see the Hibernate tab, then Hibernation is probably not supported on your computer. To save even more, set monitors to enter sleep mode after 5 to 20 minutes of inactivity.
The lower the setting, the more energy you save. The "Turn off hard disks" setting does not save much power, and can be ignored. If you are not able to select a hibernate timeout, you may need to enable the hibernate feature. If the option is available, check the power management settings and make sure power management has been enabled. Press the return key.
