When we're home, the thermostat automatically drops from 68 degrees to 66 or lower at night, for comfort as much as cost savings.
It used to be when we went on trips, we would lock the thermostat at 60 degrees to save money while we were gone.
Now, especially with Emily who gets cold easily, we're considering locking the thermostat up to 68 during our next trip so the four footed mafia is comfortable in our absence.
Never mind they have fur and will burrow into blankets if they want.
Are we suckers or what? :-)
