Oh sure. we'll be fine. We produce a bit less than half of our own gas, get a third from Norway, and the rest from "Europe" . No problem then. They won't have shortages, surely?
Finland is I think ~94% from Russia.
I suppose it wouldn't be very popular to suggest that the whole of geographical Europe is going to have to reduce consumption for a while, so the UK should help by sharing some of ours round a bit more than we'd like?
