The gas is fine, it fueled the German economic boom for decades. Stupid sanctions hurt.
The German economic boom was over in the 1970’s. Since then its been developed economy slow growth. Back when they had a boom, 1950’s-70’s their principal energy source was - coal. And energy is a small % of economic output for Germany. They will get over this pretty quick. They are a rich and capable people.
A basic grounding in the economic history of Europe, energy industries, and probably basic economics wouldn’t hurt. Its a damned big subject, but essential. I always recommend Yergin’s “The Prize” as a starter on energy, strategy and how they relate to economics. Its also a great story.
Sure, tell that to the loyal Putin troops and Russians who are being rationed of gas right now, freezing feet in the mud.
