I don't think the "EU" buys fuel. It's individual countries. The promise by the EU to buy LNG was empty. What country is going to buy it?

Russia might not have made the decision to invade Ukraine if Germany hadn't tied its energy needs so transparently to Russian natural gas.
And absent blowing up Nord Stream, might have hung Ukraine out to dry anyway.
So having to rapidly build LNG import terminals? Repaying that debt.
The German fossil gas usage in the grid has been stable for decades at around 80 TWh.
The nuclear topic neither increased nor decreased fossil gas usage to make electricity.
