Europe's response to the 1973 OPEC embargo was a decisive mobilization that exploited every advantage the continent offered. France launched the Messmer Plan, the fastest large-scale nuclear buildout in history, deploying 54 reactors over roughly two decades and pushing nuclear's share of electricity generation to around 75 percent. Britain and Norway transformed North Sea offshore petroleum into a central national project, pressing through formidable technical obstacles in rough deepwater fields until Britain moved from significant oil importer to net exporter within a decade.

West Germany's answer came through diplomacy and welded steel, as "Hvylya" reports citing a Decouple analysis. The Urengoy-Pomary-Uzhgorod pipeline, completed in 1984, ran from the vast Urengoy gas field in western Siberia to the West German border and was built over fierce American objections. The Reagan administration tried to block European firms from supplying equipment, but Bonn, Paris, and London told Washington to mind its own business, and the pipeline was completed anyway.

What cheap Russian gas bought Germany was an industrial cost structure its European competitors could not match. BASF's Ludwigshafen complex, the largest integrated chemical site in the world, embodied that bargain. German chemical producers, steel mills, glassmakers, and ceramics manufacturers built their economics around feedstock and energy costs that were simply unavailable to producers in Britain, France, or the United States.

By the mid-1990s, the results of this collective mobilization were visible in hard numbers. Europe consumed around 32 exajoules of hydrocarbons annually and produced around 15 exajoules domestically. Roughly eight exajoules of Russian oil and pipeline gas, operating under long-term contracts, functioned as quasi-domestic supply. Effective external import dependence stood at around 30 percent. The French nuclear fleet anchored cheap, firm electricity across the continent. North Sea output was near its peak. Groningen, the vast Dutch gas field, underpinned Northwest European supply.

A continent that had been genuinely vulnerable to a Middle Eastern supply cartel in 1973 had, through two decades of state-directed and private sector investment, rebuilt the physical foundations of its own security. That position would not last.
