Just to highlight this: the last significant power outage in Western/middle Europe was 2003. [1]

That's 20 years without any significant problems in the grid, apart from small localized outages.

It's not hard to start taking things for granted if it works perfectly for 20 years.

Many people don't even have cash anymore, either in their wallet or at home. In case of a longer power outage a significant part of the population might not even be able to buy food for days.

Even if you have cash many shops would not sell anything in case of a mass outage because registers are just clients which depend on a cloud to register a transaction. Not reliable but cheap when it works.

There are now ubiquitous wireless POS terminals for card payments that can be recharged from emergency sources of electricity(like cars). As long as the mobile internet works it's possible. Of course this only little alleviates the disruption.

And who's fault is that? Why did europe allow this?

Why will the US allow this, eventually?

We will use better technology for electronic transactions. Most of banks worldwide still use COBOL for most (all?) their software infrastructure.

You can do as many electronic transactions as you wish without internet or electricity, provided you have something with charged battery. Problem is the transaction cannot be verified without internet, but when internet gets restored, all transactions can be applied.

That technology exists for more than a decade, so banks will implement it in 20 or 50 years. Most sane people will not wait patiently for half a century till some software engineer implements electronic transactions with COBOL, and we will use some kind of blockchain much sooner than that.

In Spain it's now illegal to pay with cash for transactions over 1000EUR. Absurd.

In Norway they recently made it mandatory in most circumstances to accept cash for transactions up to 20,000kroner (~1700EUR): https://www.norges-bank.no/en/topics/notes-and-coins/the-rig...

I don't know but I find it very practical to not carry piles of cash in my pocket and home and know that we're less likely to get robbed just because of the cash we have.

I don't know how true the relationship between the cashless lifestyle and safety actually is, but it works and I feel ok; I'm not sure that the prospect of a few hours of national blackout once in 20 years will make me change my mind significantly.

reply
Why will the US allow this? Because there's too much money to be made by middle men who want their cut of the transactions.

Yeah, this is the turkey’s dilemma - life on a farm is a lot better than life in the wild for 51 out of the 52 weeks of the year.

Most of our modern economy and systems are built to reduce redundancy and buffers - ever since the era of “just in time” manufacturing, we’ve done our best to strip out any “fat” from our systems to reduce costs. Consequently, any time we face anything but the most idealized conditions, the whole system collapses.

The problem is that, culturally, we’re extremely short-termist- normally I’d take this occasion to dunk on MBAs, and they deserve it, but broadly as a people we’re bad at recognizing just how far down the road you need to kick a can so you’re not the one who has to deal with it next time and we’ve gotten pretty lazy about actually doing the work required to build something durable.

"Just in time" is a phrase I hate with vehement passion. You aren't optimizing the system, you're reducing safety marigns - and consequences are usually similar to Challanger.

This is a solution that teenager put in management position would think of(along with hire more people as solution to inefficient processes), not a paid professional.

Systems like electric grid, internal water management (anti-flood) shouldn't be lean, they should be antifragile.

What's even more annoying that we have solutions for a lot of those problems - in case of electric grids we have hydroelectric buffers, we have types of powerplants that are easier to shutdown and startup than coal, gas or wind/solar(which cannot be used for cold start at all).

The problem is that building any of this takes longer than one political term.

Of course not, they're optimising shareholder profit.

What are some examples of modern system collapse?

We've had substantial disruptions, but they've not been particularly irrecoverable or sustained.

reply
For the people who died of normally preventable death during covid while the health services were overwhelmed, the damage is irrecoverable. The chips shortage lasted years. Every year we become more, not less, dependent on the supply chain working. Every year we become less, not more, resilient.
reply
I don't think it's crass to separate the deaths that occurred from a novel disease from the impact it had in society. In the medium term, it's a blip, never mind the long term. There's a huge chunk of society that thinks there was a huge overreaction!

The chips shortage has been difficult, but it's also been little more than an inconvenience when you look at it in terms of goods being available to consumers or whatever.

reply
Burying lines is not a panacea, it generates massive reactance changes compared to a classic line.
reply
Honest question, are we better off in the long run, and is it a better solution, to decentralize energy generation and make more smaller grids rather than linking them all up? This isn't to say completely getting rid of the ability to transfer between the smaller grids to assist with power disruptions but to decouple and make it less likely for catastrophic "global" failures like this.
reply
With a high fraction of renewables, the reverse is probably better in the long run. The larger geographic area you connect, the less you're affected by weather systems, and the wider area you can draw dependable dispatchable power such as hydro from. But that depends on having enough grid capacity to move enough power around, which is currently a problem.

But I wonder from a reliability (or lack of cascading failures) point of view whether synchronous islands interconnected with DC interconnects is more robust than a large synchronous network?

reply
It's hard to build big generators, so as we already struggle with infrastructure I don't think that's feasible, but it would be great.
