Raise your thermostate, save electricity?

This just happens to be one of Ontario Hydro’s tips for conserving energy, to raise your thermostate 2 degrees. I just don’t understand how this is supposed to work.

The advice assumes you have air conditioning. Raising the thermostat means the air conditioner will come on less frequently and for shorter periods. If you don’t have air conditioning, raising the thermostat doesn’t do much.

Oh, I get it. Yes, I did leave out the air conditioner part because I really didn’t think that had anything to do with it.

But, I get it now. They were talking about air conditioners that come on automatically, I guess. I need to learn to think outside my manualairconditionercentric views.

Thanks, JeffB.

The basic physics is that if you raise the temperature inside then the temperature difference from inside to outside is less so less heat flows in from out. So the airconditioner doesn’t have to pump so much heat back outside and thus does less work and thus uses less electricity.
