They seppukued by walking away from cheap RU gas.
Cheap RU gas isn't just power, it's cheap industrial feedstock/inputs. Renewable/nuclear does not replace this. So all the wank about their energy policy is distraction. TLDR:
Competitive Germany industry needs cheap RU gas.
Healthy German economy with 40% trade GDP needs US + PRC, then RoW markets.
PRC market going away.
Germany "chose" (maybe pressured) into expensive US gas to keep US market, because doesn't matter manufacturing cost if you lose biggest future market, and can't manufacture without reliable source of gas. The lockin is DE gets US gas and US market access.
But Germany with expensive US gas = will eventually lose competitiveness in most other markets, so sectors will crater. Double whammy of other (PRC) being more competitive and DE making it self even less competitive.
Counterpoint: Japan doesn't have cheap feedstocks and makes cars fine.
