The Energy Weapon: Gas Politics and Europe's Dependence

Building the Dependence

Europe's dependence on Russian natural gas did not happen overnight — it was built over decades, beginning in the Cold War. In 1970, West Germany signed a "gas for pipes" deal with the Soviet Union, exchanging steel pipes for natural gas. The logic was straightforward: trade interdependence would promote stability and eventually political liberalization. This became known as Wandel durch Handel — "change through trade."

By 2021, Russia supplied roughly 40% of Europe's natural gas and 25% of its oil. Germany was the most dependent major economy, receiving over 55% of its gas from Russia. The dependency was reinforced by massive infrastructure investments: the Yamal-Europe pipeline through Belarus, the Brotherhood pipeline through Ukraine, and the Nord Stream pipelines running directly from Russia to Germany under the Baltic Sea.

Nord Stream 2, a second undersea pipeline completed in 2021 but never activated, became the most politically contentious energy project in Europe. The United States and Eastern European countries warned for years that it would deepen German dependence on Russia and bypass Ukraine (which earned billions in transit fees). Germany, under both Merkel and Scholz, resisted American pressure to cancel the project until Russia invaded.

The warnings proved prescient. Russia had used energy as a weapon before — cutting gas supplies to Ukraine in 2006 and 2009 in pricing disputes that also affected European consumers. But many Western European leaders convinced themselves that mutual economic interest would constrain Russian behavior.

2022: The Energy War

After the invasion, the energy weapon cut both ways. Europe imposed sanctions on Russian oil and coal, while Russia progressively reduced gas flows to Europe through 2022, citing various technical pretexts (turbine maintenance, regulatory issues) that few observers found credible.

By September 2022, Russia had effectively shut off all gas flowing through Nord Stream 1. That same month, mysterious underwater explosions ruptured both Nord Stream 1 and Nord Stream 2 pipelines. Investigations by Germany, Sweden, and Denmark produced no definitive public attribution, though various reports pointed to Ukrainian operatives — a claim Ukraine denied.

The energy shock hit Europe hard. Gas prices spiked to over ten times their historical average. Governments spent hundreds of billions of euros on emergency subsidies to protect households and businesses. Industries dependent on cheap gas — chemicals, fertilizers, glass, metals — faced existential pressure. Germany, which had built its economic model on cheap Russian energy, entered its most serious industrial challenge since reunification.

But Europe adapted faster than most predicted. A combination of emergency measures prevented the worst:

• Rapid construction of LNG (liquefied natural gas) import terminals, especially in Germany
• Massive imports of American and Qatari LNG
• Demand reduction through conservation, industrial adjustments, and an unusually warm winter in 2022-23
• Accelerated renewable energy deployment
• Norwegian gas partially replacing Russian supplies

Long-Term Consequences

The energy crisis permanently reshaped Europe's energy landscape. By 2024, Russian gas had dropped from 40% to under 15% of European imports, with further declines expected. The remaining flows were primarily through the TurkStream pipeline and (until its expiry in late 2024) the Ukrainian transit route.

The strategic implications are profound:

• Germany's reckoning: The failure of Wandel durch Handel forced a fundamental reassessment of German foreign policy, encapsulated in Chancellor Scholz's "Zeitenwende" (turning point) speech. Germany increased defense spending, sent weapons to Ukraine, and accepted economic pain to reduce Russian dependence.
• Europe's energy transition: The crisis accelerated the shift to renewables. Solar and wind capacity expanded rapidly, partly driven by energy security concerns rather than just climate policy.
• Russia's lost market: Europe was Russia's most lucrative energy customer. Redirecting gas exports to China requires new pipeline infrastructure (the Power of Siberia 2 pipeline remains under negotiation) and China demands much lower prices. Russia's gas revenue fell sharply.
• Global energy reordering: Russian oil and gas found new buyers in India and China, but at steep discounts. The global energy map shifted, with the US becoming Europe's largest LNG supplier.

The energy dimension of the conflict illustrates a broader lesson: economic interdependence can be a source of vulnerability as well as stability. The liberal assumption that trade prevents war proved dangerously naive when one partner was willing to use energy as a weapon.
