I'm not aware these two latest are any worse than those we've been through (a lot worse) before. And society has always coped before.
So, whilst I'm not suggesting there is no reason for Government giving warnings, I don't see these storms as any "proof of the need".
I dont believe its winter storms thats prompted this, the national energy system operator recently warned demand might exceed supply this winter, leading to power outages. OFWAT have made warnings about water supplies due to demand exceeding supply from reservoirs. Supermarkets have made similar warnings about food chain supply issues, which have really high risks caused by disruption to their just in time delivery model, remember when lettuce suddenly disappeared off the shelves, or bread. What happens if a major logistics firm goes bust because of the cost of diesel and the cost of doing business has trippled.and supermarkets get no deliveries. One of my local supermarkets fridges broke (they werent cyberattacked) earlier this year, it took weeks for them to actually restock properly.
I mean blimey Spain only last year lost their national grid for a day, and some places took 3 days to recover properly, and you couldnt pay by card, or really do anything but sit and wait it out.
