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.

Point is, gas recervoirs are filling faster than anticipated. Which I call success in the current environment.

The gas reservoirs don't hold enough to get through a winter. They hold enough so that with normal inflows, there's enough gas in the winter - while drawing down the stocks.

You need both ~full storage and continuing supplies to get through a winter.

Sure. And still ir stands that reservoirs are filling up faster than anticipated. I'm in supply chain, and if during a period where inventory is hard to come by said inventory is replenished faster than planned, that is usually a good thing.

Ask Bosch to build the heart pumps. Highly efficient, run on electricity.

Sure, and that will be done, including installation, for 80 million people before Christmas. 2022 that is. Or how much do you think such a transition will take?

Sure, it can be just start in 2002.

In which it wont help a single bit in the short term. Like masks and vaccines during Covid, you need short term fixes until something mid to long term is put in place.
