Yes, it would be interesting to put a Kill-A-Watt on the fridge for, say, a week in January and then a week in July.

I have found that when I visit other people's houses in the winter I darn near keel over from heat stroke.

And more about thermostats: I highly recommend programmable stats for those with a regular work schedule that leaves the house empty for that time. I used to set mine back all the way to 45- as low as it would go- for the "away times", and sometimes I knew the furnace didn't kick in at all when I was gone because the temp hadn't got down to 45 yet. There was never any suffering involved since it kicked the temp back up right before I got home. But I don't have that situation now so I just program it for a single temp.
