RayB is correct to give you a basis for comparison my electric bill was about 70.00 a month with incandescent bulbs. I replaced all of my incandescnet bulbs with flourescent bulbs and just started shutting everything off when it wasn't needed and my bill went to about 50.00  :o

Shutting off anything that's not needed means lights as you move throught the house (nod to BobA)...or you can get sensors.

Question: aside from being automatic, how is hibernate different from stand-by?
NOP:
Hibernate is when the contents of system RAM are written to the hard drive, and the machine is shut off, minus the bit that monitors the keyboard or button that you use to wake it back up again.  When the machine wakes up, the system needs to restore the state of RAM by loading it off the hard drive before you can continue.

Standby is 1 step above Hibernate, where instead of writing RAM out to the hard drive, it keeps it in self-refresh mode.  Standby uses more power than hibernate.  With hibernate you could physically remove power to the machine and still recover when power is turned back on.

So whatever files and programs you have active and internet pages up an all will be restored, exactly, from hibernation?

Yup.  Everything that was in main memory (including any active programs and data being used by them) would be tucked away on the hard drive and then restored when you came out of hibernate. 

In fact, you could (although I'm not sure if I'd recommend  this!) edit a word document, not save it, go into hibernate, remove the power plug, come back 2 weeks later and come back out of hibernate and your document should be there in its unsaved state.  At least that's the way it's all SUPPOSED to work.   ;)

It is actually a pretty complicated trick.  I used to work on BIOSes for PCs a few years ago, and there were countless things that had to be dealt with when performing this, like also saving the state of all the other hardware (video card, network card, etc etc)  I'd think that modern machines should have this pretty well ironed out-give it a whirl!  It does take a bit of time to restore everything back, but it still should be faster than loading an o/s from scratch.
