I think there's a great deal of hysteria about Russian gas cutoffs. German bills are projected to be lower than UK energy bills over the winter[0][1], even though the UK has basically no dependence on Russian gas.
A war is an unusual and extreme event, and when it's started by your major gas supplier, it's unsurprising that prices go up. It is, however, obviously not enough to write off the whole european energy policy just because when you stress test it, there are higher bills.
It's no use if your 'sensible' energy policy results in 3 degrees of global warming: that will be far worse than a high energy bill, or a war for that matter.
This is not exactly the best time to be talking about Europe's superior energy infrastructure.
