What is the benefit of using gas instead of electric? You are still spending money and burning carbon.

I have been told that turning the Water Heater down is excellent since that one device uses more power than any other appliance in the home. I wonder if having it shut off unless for an extended time (like a trip out of town) since it will work that much harder to get the temperature back up.
I know for a fact that with heat pump heating there is a point where it costs more to drop the temperature very low at night than to just reduce it a smaller amount since you have to reheat the house in the morning and the system will kick into auxiliary (very inefficient) heat if the gradient between the room and thermostat is more than a few degrees.
