Europe is facing another major energy challenge as geopolitical tensions continue to disrupt global energy markets. The latest pressure has once again exposed the risks of relying heavily on imported fossil fuels.
The continent has faced several energy shocks in recent years. However, the next crisis could emerge from a different source.
Instead of another war or sudden supply disruption, declining global oil production could create a slower but equally serious problem. Europe’s heavy dependence on foreign suppliers could make the region particularly vulnerable.
Europe Struggles With Repeated Energy Shocks
Europe has experienced its third major energy crisis in four years against a backdrop of persistent geopolitical tensions.
Russia’s invasion of Ukraine in February 2022 created one of the biggest challenges. At that time, European countries relied on Russian producers for around 40 percent of their natural gas.
The conflict disrupted European energy markets and forced the European Union to rethink its relationship with Russian energy suppliers.
The region has since faced additional challenges. Conflicts affecting shipping routes in the Red Sea disrupted energy transportation during 2023 and 2024.
Now, the war involving the United States, Israel and Iran has created another source of uncertainty. The situation has placed further pressure on global energy supplies and transportation routes.
Europe is also dealing with another growing challenge. The continent is warming faster than any other continent, increasing climate-related pressure on its energy systems.
Strait of Hormuz Raises Fresh Energy Concerns
The closure of the Strait of Hormuz has added another layer of uncertainty to Europe’s energy situation.
Before the latest military operations in the region, around one-fifth of global oil and gas trade passed through the strategic waterway on an average day.
“We swore we’d learn. We promised things would change but here we are,” a ‘highly frustrated European diplomat’ said.
The official also warned that European leaders were focusing on immediate energy concerns instead of preparing for long-term challenges.
“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.”
The comments capture the frustration surrounding Europe’s repeated struggle with energy security. Each crisis has forced governments to react quickly instead of focusing entirely on long-term independence.
Europe Has Reduced Its Dependence on Russian Energy
Europe has made considerable progress in reducing its reliance on Russian fossil fuels since 2022.
The Kremlin no longer has the same level of influence over European energy supplies. Nevertheless, the bloc remains heavily dependent on imported oil from several international suppliers.
Official European figures show that the EU imported 435 million tonnes of crude oil in 2025. The bloc spent more than €212 billion on those imports.
The figures underline the scale of Europe’s dependence on international oil markets. They also show why global supply disruptions can quickly affect European consumers and businesses.
Diversifying suppliers can reduce dependence on any single country. However, diversification alone may not protect Europe from a broader decline in global oil production.
Peak Oil Could Become Europe’s Next Challenge
Europe’s next energy crisis could come from a gradual decline in global oil production.
Unlike a war or sanctions, peak oil would not necessarily trigger an immediate supply shock. Instead, production could gradually fall as major oil fields become older and resources become harder to extract.
“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.
The problem could become more serious as additional oil-producing countries reach their production peaks.
“As more exporting countries pass their production peak, fewer producers will be able to increase output when markets tighten, or supply disruptions occur.”
For Europe, that situation could make future supply diversification increasingly difficult.
“For an import-dependent region such as the European Union, this means that diversification alone may become increasingly difficult over time.”
The warning matters because several major oil producers are already dealing with ageing fields and finite reserves. Declining exports could therefore create pressure gradually before the full impact becomes obvious.
Europe Needs Greater Energy Independence
The potential consequences extend well beyond higher energy prices. A prolonged supply shortage could increase energy poverty and weaken European economies.
Energy insecurity could also create wider strategic risks. Heavy dependence on foreign suppliers can leave countries exposed when geopolitical relationships deteriorate.
Europe therefore faces growing pressure to accelerate its transition toward domestic clean energy. Renewable power, energy storage and other alternatives could help reduce dependence on imported fossil fuels.
However, the transition requires long-term investment and coordinated policies. Governments also need reliable energy systems that can handle periods of high demand and supply disruptions.
The repeated crises have already demonstrated the cost of waiting until markets become unstable. Europe now has an opportunity to use those lessons before another shock arrives.
The next energy crisis may not begin with a dramatic military conflict or sudden blockade. Instead, it could develop quietly through declining oil production and shrinking export capacity.
That makes preparation even more important. If Europe fails to strengthen its energy independence, the consequences could extend from higher prices to economic instability and broader security risks.
The continent’s biggest challenge now is to stop reacting to each energy crisis separately. Europe must build a system capable of withstanding geopolitical shocks, climate pressures and a future with less readily available oil.
