Simple replacement. Germany also uses gas for 12% of its electricity generation. Every bit of gas not used for electricity generation is gas saved for heating and so on.
"since Germany is filling up gas reservoirs atm I'm not even sure how bad the shortage really is"
What are you talking about? It's summer, gas is used for heating, of course it's not a critical issue per se now. Germany is saving gas for the winter, when it heavily uses gas and when Russia will almost certainly cut off the remaining supplies.
And for what it's worth, Germany is already beginning rationing actions for energy starting tomorrow, so even now there is actually already some urgency, which will grow as it gets closer to winter.
For reference: The nearest grocery store to me is 3 km away, down a hill and across an interstate that does not have a method for pedestrians to cross it, other than playing Frogger, if you know what I mean. And that store is overpriced and doesn't have a good selection. The next-closest store is 8 km away.
