Part of me really wants to see the lights to go out - to have electricity to several cities out for several days, ideally a few weeks. I suspect that most people, if they did adjust, would do so poorly.
People would struggle when they find that they can't use a vacuum cleaner, or a dishwasher... or suddenly discover that to wash clothes, they have to do so manually - no more set and forget. Drying clothes becomes a matter of hoping for a warm enough day, or hoping that they'll dry in front of a fire place if you have one - and the wood.
The twentieth century was notable for the labour-saving devices that were introduced, and the social upheavals caused by such introductions.
What would happen if they were suddenly taken away? I don't deny that I use them, and haven't made any substitutes anywhere as much as I would like.... Zeer pots are on my list, amongst many other things...
