Power is still out for many thousands of people in the wake of two hurricanes. People are suffering. It’s my belief that surviving without electricity is harder in the south that here up north. Fresh food goes bad rapidly in the heat. Fortunately there are many foods that can be stored long term without refrigeration.
The lack of air conditioning can be more of a hazard to life. Staying the shade and drinking lots of water helps. If you are young and healthy surviving without AC, while uncomfortable, is generally doable. The very young, the sick, and the elderly may need AC to survive.
For that you need electricity, and not just a few watts either. You aren’t going to get by with a couple of solar panels and a solar generator. A gas, propane, or diesel generator will do the job -until the fuel runs out. For a lot of people in the affected areas getting more fuel is a real issue. Storing fuel in large volumes requires serious safety precautions.
There are ways to make your fuel go longer. For example rather than trying to cool the whole house limit AC use to one room. Running one smallish AC unit will provide a safe place for the vulnerable. It might be crowded and lack privacy but your fuel supply will last longer.
Where I live in New Hampshire AC is not an issue. My house doesn’t even have AC. A few fans suffice. Losing power is a winter issue. On the plus side, refrigeration is easy. All of outdoors is a freezer. Staying warm is the real problem.
Fortunately a woodstove doesn’t consume any electricity. Fire is primitive, one of first technologies, but it still does the job. In my case, living in the woods is a bonus. Firewood actually does grow on trees.
