Two Anecdotes to this...
I'm a bit late chipping in but here are two comments.....
1) About 15 years back, the company I was working for took on a new recruit. A networking guy in his early 30's, who had come from the power industry, and work on "safety critical" systems. During the first few weeks/months whilst fitting in with the team, he would chat about his previous employment. Even back then he was commenting that the power industry was heading into a huge black hole (which the power companies were all aware of), and that by 2015-2020 the UK would be in a major power crisis: - old power stations (30-40 years old) were being or were scheduled for shutdown, coal was coming to an end, "green pressure" was starting to bite on all fossil fuels, the UK had not researched or kept up with nuclear development since the 60's, etc, etc, etc, and meanwhile our appetite for electricity was forever growing - not just at home, but our business in those days of the mid/late 90's was data centres and PoP's which were starting to appear and munch through kilowatt hours at an alarming rate.
2) At around the same time, give or take 5 years or so I was driving one morning up the M6. I was stabbing the buttons on the car radio and ended up on some local station somewhere. There was an article on the news about a power cut the night before which had left umpteen thousands of homes in the area with no power all night. After the news the DJ stepped in to have a little "backchat" with the newsreader and commented that he was one of the homes that had been blacked out. He and his wife had to fumble around in the dark to find if they had some candles and matches somewhere, whilst his kids thought it was really exciting and spooky with no power, and thought that candles were only for birthday cakes and couldn't actually be used to produce "real" light. He then went on to say, that after five - ten minutes the kids started to realise there was no TV, no DVD, no computer, no cordless phone, no microwave, no warm food, no light in the fridge, no heating, no light to see anything by anywhere except a couple of solitary candles, and then started to get really stressed about the lack of electrcity. The DJ/newsreader then went on to comment about how reliant we were now on electricity compared to when they were youngsters (aka in the 70's) when such things were relatively frequent and how we are not prepared for it, and how his kids had never ever experienced a power cut or had any concept that such things happened.
I'm not sure why I remember both anecdotes so clearly after all this time, but there was obviously a connection between them, and I guess it started to make me think about what to do if the power is off for more than 15 minutes every five years, or whatever we take for granted these days.
