We don't have to replace it, well not in the short term. Just turning thermostats down a little, increasing insulation, stopping doing low value things with gas that we don't need to do, shifting electricity use to times when we have wind/nuclear available etc. is enough to ride this winter out.

And the whole point of "begger thy neighbour" is that it hurts you. So saying "I still really want to punish my neighbour because this is his fault" is literally punishing yourself. It doesn't make sense.

As I said, not a technical problem, a political problem.
