I worked on the family dairy farm decades ago, you learn to deal with all kinds of situations for sure from sweltering heat to freezing cold!
On the family farm we had a generator that ran from a tractor PTO. With no power in the cold that meant we would not have the block heaters to help start our tractors. We had a couple utility tractors (as opposed to the larger field tractors) with that had glow plugs like I suspect most diesel cars and trucks have today. With that we could run the generator to milk the cows, maybe with some power left to run a block heater on another tractor, and then use the tractors to mill and auger feed for the cattle and pigs after milking was done.
I asked Dad once what we would do if we could not get those tractors started in the cold and the power was out. He said the cattle likely would not be producing any milk regardless. I took that to mean they'd have stampeded off for Oklahoma, got horribly sick, or froze to death.
If the power was out in the heat then we'd need the generator running to keep the well pumps going, and if the animals don't have water in the heat then that can kill them. With no hay bales freezing together in the heat we could manhandle some hay to save on running the silo unloader, that took a lot of power that the generator could barely handle. If the local feed store had power then Dad might take the shortcut of just ordering milled feed than mill our own.
Now as a homeowner I carry that experience to how I maintain my home. The last time I had the power out from a summer wind storm I ran a small generator through the night to run the refrigerator, a couple lights, cell phone charger, dehumidifier, and a fan to keep me cool as I slept. I could hear generators running in the neighborhood where others were similarly equipped to shelter in place that night, not doubt many of them were purchased after the much larger power outage a few years prior. One brother got a whole house generator, and sold me his portable generator for cheap. Now I have two generators, one LP and the larger one gasoline. I don't need two generators but it's nice to have them. Maybe I can make a trade somehow to a tri-fuel generator. The third fuel for a tri-fuel generator would be using the natural gas supply to the house for fuel.
Losing just electricity meant I can still have hot water, the city water and gas often still runs. I can lose any one of the city utilities and manage for some time at home. Lose two services and I can do things like flush toilets using the water from the dehumidifiers, and get heat from either electricity or gas. Lose all three? I'm packing up my truck and paying a visit to my brother with the whole house generator and on-site well.
