Hi,
I love out of the ordinary ways to save energy.
- We use an electric mattress pad so that we can increase the setback more at night and still sleep warm. It saves a surprising amount of propane:

- We have one of those lever type faucets on the kitchen sink -- so, when you move it left you get hot, right you get cold, and in the middle you get warm. I read a study that said that people with these faucets tend to keep it in the middle (warm water) when they don't really care what temp they get -- the study said that if you remember to push it over to the cold side when cold is OK for what you are doing it saves a significant amount of hot water!
- I guess using bubble warp to insulate windows has gotten to be pretty well known -- we do that.

- In the rooms we don't use much (like guest rooms), we have rigid insulation board inside panels.

With these ones that leave a gap at the top, you still get quite a bit of light.
- We recently switched to a really efficient pet door. This was after we had a blower door test, and the old pet door leaked so bad we had to plug it to get a valid reading on the blower door.

This pet door has a really innovative double magnetic seal.
- I have all the chargers for my battery powered tools on a timer so that instead of sucking a little power 24/7 they come on for half and hour a day and top up any batteries that need it.

The gang of chargers use 22 watts 24/7 without this timer -- 200 KWH a year.
- When we had to replace our TV a 6 months back, I really obsessed over -- finally found a Sharp 46 inch that only uses 53 watts! A third of what the old 36 inch TV used. CNET.com has the best reviews on TV's, and carefully measures power consumption.
- This is one that the guy who runs 12VoltMan.com sent in. He uses the just the pilot light on his gas water heater to heat all the water for two people.

There are some ins and outs to this, but I think its a sound idea, and safe as long as you know what you are doing.
- Ray turned this one in -- a homemade fridge that runs on 100 KWH a year:

- This one from Doug -- "Hot water/Cold Beer" -- basically a homemade heat pump that simultaneously cools homemade beer and heats water in the hot water tank!

- Neat idea for a really efficient shower:

In the "I never would have guessed it wasted that much energy " category:
- Did you know that your DVR (TIVO) uses 50 watts 24/7?
- We wasted $3200 on propane over 8 years by having this hot water recirc system that eliminates the wait for hot water in the far bathroom:

They can be very very wasteful depending on which kind you have.
