In cold and hot places, you cannot easily buffer heating and AC for hours.

  You can if you have decent insulation (which at least cold climates do). In fact people historically have taken advantage of cheaper night time electricity prices to shift heating to night time. Better insulation will become a more attractive investment than in the past.

      > Night time is usually when heating is most needed. If we are still talking about cold climates where houses are well insulated, it's a more convenient timing but not really needed. If you cut heating for half the night or even more, indoor temp won't drop too much even if outdoor temp is notably lower than day time. It might drop a few degrees as you are sleeping warmly tucked in, but that's not dangerous, and you can still heat your bedroom if you want to avoid even that slight adjustment.
