Every once in a while, I think about how we’d survive without electricity. This is mainly a winter thought, although people have died in heat waves in recent summers.
But picture a cold snap in winter, temperatures below zero, and suddenly the power goes out. Your fireplace is only going to help until you run out of firewood (and old furniture and books).
If I take a moment to plot negative strategy, i.e. “think like the enemy,” I realize they could destroy a city by simply blowing up the grid at some key juncture, or cutting off the natural gas pipelines that feed more and more of our power plants. Makes me hope we keep a plentiful supply of coal on hand in the case of having fuel, and that we could whip up a new high-tension line if needed. I might also consider a backup generator at the old hacienda, if I let these thoughts get into a survivalist mode. (And of course, I know a close relative who heats the house with wood.)
