It was the one where he was talking about his heating and cooling strategy; he cools/heats his house overnight when electricity is cheap and then lets it coast during the day.

Maybe 80 is too warm, but going up a couple degrees to give yourself a bit more comfort if the power goes out seems like a sound principle.
