They rely on the grid. Just like the rest of the connected countries. Just like nuclear country France does.

What kind of energy is cheap at the moment there is irrelevant. If nuclear energy would be turned off on the grid, like it happens all the time when the French fleet needs repairs again for example, no lights go out in Austria. Just like no lights go out in France.

What you do is the same thing as making fun of humans because they rely on supermarkets and don't go out on the streets and shoot some animals.

Times change.

Germany only followed after their Wackersdorf debacle, matching Tschnernobyl, and then finally Fukushima.

The rest of Europe is still in the hands of the energy lobbies.

And Austria does not rely on nuclear at all. It's rather the other way round, that all the others rely on Austria (and Swiss) expensive peak energy from their high mountains. When Europe turns on all it's power switches at the very same time the grid would collapse without Austria.
