On the topic of pulling the plug, a friend of mine was sharing a car with a friend of his who happens to be someone high up in the local police force, and they were driving through the midlands, heading south.
At one point they passed some fenced off piece of land and the cop pointed it out. ‘That’s one of the major junctions on the national grid,’ he said. ‘And if the shit ever hits the fan for real, if we ever have some major political or social problem and power becomes an issue, let’s say that IS nukes a power station or two, that’s the point at which we cut off power to the north. The south will stay on the grid but the north gets left in darkness.’
Which is good to know.
