No surveys or studies needed to address this question. The Second Law of
Thermodynamics decrees that the speed and extent of all heat transfers in
the universe depends solely on the temperature differential between two
objects. The moment you turn down the thermostat you start saving money. The
longer you keep it down, the more money you save.

Yes, you save energy turning it down. In balance less heat is lost.

What happens when he comes home and turns it back up again? The
reverse, so where is the savings?

RickH-
Looks like there is very little hope for you understanding the thermo
of setback....
Walter made a very simple / concise statement of the value of setback
but you still choose to disbelieve it. :(
The energy saved is the amount of energy used to maintain the house
at the setback subtracted from the energy that would had been expended
to maintain the house at the higher temp.
outside temp 50F inside temp 70F (without setback)
outside temp 50F inside temp 60F (with setback)
house at setback temp loses ~1/2 the heat that the house at "normal"
temp
cheers

now if we could just get people to not top post

Hmm,
Talking about manually doing it? No, doing it with intelligent
programmable 'stat.

The energy you buy is the same energy as what's lost. Cold
house loses less heat. The recovery swing is a lot less heat
than keeping the house warm.
* It may take a long time, which is unacceptable
* It may cause your heat pump to go into emergency heat,
which is more expensive

The
reverse, so where is the savings?
