We have lived in this house for 22 years. One winter we had an ice storm and lost power for a few hours, but the fireplace kept the house warm enough. The power came on and all was fine. One spring a severe thunderstorm blew over some trees onto a major power pole and caused a wide area power outage one evening. My wife's brother and sister in law were spending the night. It was warm, but not hot, and my BIL said he did not get much sleep because he had to get up and spin the ceiling fan over and over.
Since the power was still off, for breakfast we ate the ice cream that was getting soft. My BIL could not wait to get home to tell his friends that know my wife that she served him ice cream for breakfast.
Every time we have a thread like this, I get the urge to get a generator. My neighbor has a whole house generator by Generac. He has had it for 12 years and it has run for 30 minutes total to provide backup.
We have city water, so the water supply is not an issue. We are never going to have a major flood like the residents along the Mississippi get regularly. Hurricanes and tsunamis are just not a possibility. A devastating earthquake like California has had and will have is not remotely likely. Mudslides and hillside slumps are not going to happen with no barren steep hills. At worst a tornado like the one that hit Moore, OK 30 miles from me with 300+ MPH winds devastated one very small area. Just a few block away was full civilization and help. The area hit was just debris and loss of power was not an issue when the house is gone.
I have enough friends that we could spend a few nights with if indeed our area had a real power issue.
We have a large upper end (expensive) long term assisted living home just 6 blocks from our house. I suspect we are on the same power grid as they are. The last major ice storm that crippled Texas was two weeks of cold and snow here, and we never had more than a momentary power blip.
