I won't say that good things have come from this war, but it certainly is a wake-up call for countries to get their future plans in better order.
There is simply no excuse for the most industrially advanced country in the world (Germany) to have slacked off so much when it comes to energy. It must be some political angle, because not too many years ago Germany was one of the leaders in expanding their renewable energy sources.
France here... Seeing how things were turning in May I turned my open fireplace into a closed one (way better efficiency) and ordered metric shit-tons of dry wood (I've now got enough for at least two years). Thankfully my house ain't using natural gas at all so at least I'm dodging that one problem. Now electricity may be rationed this winter: dunno, we'll see. But at least I won't be dying of cold.
Heating oneself burning wood has this advantage that it's stone-agey enough: chop a tree into smaller pieces, let them dry for a year, you can heat now heat your house during winter.
And nobody can "ration" me / prevent me from putting wood in the fireplace: that's the "stone age" part of it. The main french electricity company, on the other hand, is ran by state apparatchiks and if they decided to ration electricity (because, by "chance", half of the nuclear reactors are all simultaneously down), I'm pretty much sorry out of luck.
Overall I'm pretty disappointed by the EU (I'm an EU citizen) and plan to GTFO. I tried last year but it failed (residency was hard to obtain where I tried to go) but I'll very probably try again.
What do you mean with the quotes? It's not by chance, it's due to backlogged maintenance (due to Covid) and some corrosion issues in a few reactors. The plan is to have all maintenance over before the winter.
Up to Russian invasion this February: old oil furnaces were being avidly replaced with natural gas ones. Solar installations were starting to slack off. Lots of re-roofing and new exterior wall insulation.
Since then: no slacking in the roofing and exterior wall insulation, but now everyone has a keen interest in heat pumps, and solar panels are being installed everywhere.
Gonna be hard to convince people to take their chances again with a fuel from such an unreliable source in the next few years, I think, especially if this is a bad winter and rationing happens.
