| >>If and when it happens things will get fixed Yes, but the timing of those fixes could be an enormous problem From what I've read, a large part of the problem will be burnt-out transformers all over the grid, from the major stations down to the street-level. Replacing any one of those is only a job of a few hours, when you have one available. The problem is that fabricating them takes a long time, and there is nowhere near enough inventory to replace the numbers that would fry in a Carrington-like event (or an EMP attack). It could take YEARS to replace them, during which time the economy is pretty much back to the 1800s, but with 2000s-level population to feed. The estimates to create a stockpile of transformers so that they could be replaced in weeks-to months range around $500 million. It would give the nation a huge strategic economic advantage to be able to fully recover on a timescale of double-digit weeks instead of years. But, since the problem is so un-sexy that it is never brought up (the last infrastructure bill would have been a good time to do so). Even if we could individually have power with rooftop solar+battery (also sufficiently protected), it'd be hard to thrive with the entire transport web broken (no grid electricity to pump gasoline/diesel, etc.). Still, I want to know how vulnerable is rooftop solar, and what it would take to protect it (and prevent an event from burning down the house). Any experts have some pointers? |
It also isn't correct to assume that the grid is wholly unprotected. Substations have extensive protection in the form of interrupters. We will lose power in a Carrington scenario, potentially for days, but there won't be an apocalypse of exploding transformers. If that happens, nobody is going to care too much about charging their Teslas. They will be too busy fending off hordes of radioactive zombies.
