This post was inspired by Robatoy's post re energy waste using single
lever faucet.

Some years ago I read the results of a study conducted by a local
power company. They installed a TV camera to record which members of a
household made what adjustments to the thermostat.

The results, as would be expected, showed the bill payer was able to
be comfortable at a higher temperature in the months requiring air
conditioning and a lower temperature in the months needing warming.
The remainder of the family needed more energy expenditures in both
the heating and cooling seasons.

No big surprise here, it all seems to depend on who's ox is gored.
