Europe's Next Energy Crisis Won't Be a War, It'll Be Peak Oil

• A new report from the National Interest warns Europe's next energy shock will come from peak oil, not war or climate, as exporting nations hit terminal production decline.
• 
  
• The EU imported 435 million tonnes of crude oil in 2025 and spent more than €212 billion, remaining heavily reliant on foreign suppliers even after cutting Russian imports.
• 
  
• Diplomats and analysts warn Europe keeps repeating the same short-term scramble after every crisis, from Russia's invasion of Ukraine to the Red Sea attacks to Iran's closure of the Strait of Hormuz.

Europe is currently contending with its third energy crisis in four years against the backdrop of near-constant global geopolitical friction and fracas. The continent’s over-reliance on foreign fossil fuel imports has been thrown into sharp relief in recent months and years as the European Union has struggled to catch its breath and stabilize markets in the vanishingly short time spans between global oil shocks.

When Russia invaded Ukraine in February of 2022, Europe as a whole depended on Russian producers for 40 percent of the continent’s natural gas. This threw European markets into turmoil as the European Union struggled to set and maintain sanctions on Russian energy exports, kickstarting a pyrrhic war between Brussels and the Kremlin. Europe has never fully recovered from that turmoil, as it has since been battered by conflicts blocking the passage of the Red Sea in 2023 and 2024, and now the United States and Israel’s war in Iran. On top of these geopolitical shockwaves, Europe is now the most rapidly warming continent in the world, causing an unprecedented climate-related energy crisis in the region.

“We swore we’d learn. We promised things would change but here we are,” a ‘highly frustrated European diplomat’ was recently (anonymously) quoted by the BBC in response to market turmoil driven by Iran’s closure of the Strait of Hormuz, through which one-fifth of the world’s oil and gas trade flowed on an average day before the United States and Israel began their military operations in the region earlier this year.

“Instead of concentrating on much-needed long-term plans - about how to make Europe more competitive in this increasingly volatile world, [European] prime ministers and presidents are now in a panic over [energy] prices, worried about angry voters and scrambling for short-term solutions,” the source continued. “Just like the crisis after Russia’s fullscale invasion of Ukraine. Different conflict. Same European divisions; same dilemmas over energy. We can’t keep going round in these circles. Something’s got to give.”

Indeed, if Europe does not learn from its previous mistakes, much, much more disastrous crises could be just beyond the rapidly warming riverbend. A brand new report from the National Interest warns that Europe’s next energy catastrophe won’t come from global conflict nor from climate pressures, but from peak oil.

To be sure, Europe has made major progress when it comes to weaning itself of its dangerous reliance on Russian fossil fuel imports over the past four years. But while the Kremlin no longer boasts the same leverage over the European Union, the bloc remains problematically dependent on foreign oil from a variety of sources. According to official figures released by the European Council, the European Union imported 435 million tonnes (Mt) of crude oil in 2025 alone, representing an expenditure of more more than €212 billion.

If the EU does not hasten its transition away from fossil fuel imports and toward indigenous clean energy development, it could be caught flat-footed by terminal oil production decline, warns the National Interest. In fact, many of the bloc’s key importers have already started to see waning exports thanks to ageing wells and finite resources. And the result will be a much more insidious and hard-to-detect crisis – until it isn’t.

“Unlike wars or sanctions, terminal decline does not create an immediate supply shock. Instead, it gradually reduces the amount of oil available for export,” the report states. “As more exporting countries pass their production peak, fewer producers will be able to increase output when markets tighten, or supply disruptions occur. For an import-dependent region such as the European Union, this means that diversification alone may become increasingly difficult over time.”

What is more, the potential fallout from the next crisis could extend far beyond market turmoil and energy poverty. Without energy autonomy, the continent could be rendered extremely vulnerable to foreign aggression. Energy insecurity could pose a far greater threat to European safety and freedom than any weapon if expert warnings continue to go unheeded.
