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.
