How does having to turn my lights on at 5:30 P.M. save energy? I’m sure when they started daylight savings time people went to bed a lot earlier and I can’t help to think it’s outdated!!! Do you agree?

My roommate and I are having a little “disagreement” about our window AC. I like to turn off the AC when I leave the apartment to save energy. She likes to leave it on all day on 73 because she thinks that it saves energy and she is hot natured and doesn’t like the apartment hot when she gets home. Please tell me that she is wrong.

David S asked:


Specifically, I am wondering if a recirculating whole-house water pump, which keeps hot(ish) water circulating through the pipes makes sense. Currently, it takes literally one full minute (OK, 57 seconds in my test today) for hot water to reach the sink in our upstairs bathroom from the water heater tank in the basement. A recirculating pump would reduce that time to zero and save a lot of wasted water (not to mention getting my kiddos to wash those germies with warm water), but it would waste some energy heating the water in the pipes (which cannot be insulated as well as a tank) and moving it around. Do the water savings justify the increased energy use?
