Whoever you’re arguing with on this point, it isn’t me. Hell, you quoted the part where I said raw numbers weren’t the problem.
As Czarcasm said, “if a power plant needs 100 people working to keep the place running, and 80 of them disappear, the plant doesn’t simply put out 20% of the power it did before-it quits running entirely because the minimum crew to operate it just isn’t there any more.”
Now, this is happening at every power plant in North America. So there’s no power for the cell phone towers or the landlines or the Web. Most people have whatever gasoline is in their cars, or that they can siphon out of their departed neighbors’ cars. So they can’t communicate over distances, and there’s a fairly low limit to how far they can travel.
It’s gonna take them awhile just to figure out what’s going on, because there’s nobody in a position to know who can tell them. And even when they do, the difficulties in terms of reorganizing are severe. How are the workers at a bunch of power plants in southern California going to know what kinds of workers are missing from which plants, besides their own, of course? How are they going to communicate this to each other, and decide which plant to all meet at and keep running?
Once power is restored on some limited basis, who’s going to support the power plant workers in their endeavors, since nobody’s paying them to do this (no money, for all practical purposes), and time spent keeping the electricity on means time not hunting for food and gasoline? And when the power comes on, how long will it take to get the other puzzle pieces back together? How long will it take for one bank to function again (its employees will mostly be missing too), and will a bank have any meaning by the time it does?
And while things are confused, while there is no power or communication, how are people going to act? Most will behave semi-ethically at first (but once one person smashes the supermarket window, everyone else will be in there, looting the shelves as well), but there will be predators, they will have no restraints, and they will have the upper hand at first. Most people will have to devote a lot of energy to hanging on to what’s theirs, rather than putting our economy as we know it back together again.
ETA: And how long can a power plant keep running once it’s back up, absent deliveries of coal or natural gas or whatever it runs on?
