Behold! If you have a gas well on your property, you're gold!
I don't know about the gas operated coolers and freezers, but for things like stoves, propane and natural gas take different sets of fittings. I wouldn't swear that you can find the right fittings to switch for all manufacturers and models.

One thing that I've often thought about would be the advantages of setting everything up to run on intermittent power. When you are close to the end of the power companies lines, electricity can be rather unpredictable at times.
I've thought about getting solar panels so that when the power is out, I can still keep going. Refrigeration would be the main problem in the summer. The house stays relatively cool even on very hot days. The only air conditioner we have ever had are swamp coolers. I've always been fine without them, and now that my thyroid has failed and I'm cold most of the time anyway, I can do fine without air conditioning.
I rarely watch tv -- I think the last time I had it on was for about five minutes to watch the last minute or two of the super bowl. I do like to listen to radio or recordings, though, on occasion. (At this mornent, I'm listening to an old Roy Rogers and the Sons of the Pioneers album.)
Hot water would be nice. I know someone who rarely takes a bath. I think he just washes his crotch and underarms and maybe his feet for the most part. I don't know if I would want to go that far, though.
One thing that I have long thought would be nice would be to build a home into the side of a canyon so that you could have a nice view of the country in front of the house and it would stay at about the same temperature year round. With my thyroid, though, it would be too cold for me any more.
