Unless you live in an utterly isolated part of the world, or are part of an Amish community, (in which cases you would not be reading this) you have been impacted by temporary power outages. They range from the nuisance level of a couple of hours, to the major headaches associated with those lasting several days, especially in intemperate weather.
At least that's the case in the US and most developed nations. For some unfortunate nations, the power is out every day for several hours.
But what if it were to go out and stay out for a year of so? Catastrophe.
Preppers might like to proclaim their independence from the power grid, and the Amish might claim they don't use it anyway. While it is true they might be able to survive without connection to electricity, their ability to permanently survive without electricity requires that they not be dependent at all on entities that do require power — for example the manufacturers of life-changing and life-saving medications. And that's not so easy to accomplish.
