For the European Union, the short-term consequences of Iran’s blockade of the Strait of Hormuz — steeply rising gasoline and diesel prices, and a severe jet fuel shortage putting foreign travel at risk — could be dwarfed by the long-term implications of a prolonged closure. An industrial crash, higher manufacturing prices passed on to consumers in the form of damaging inflation, fertilizer shortages and resulting spikes in food prices, and higher household utility bills all have the potential to upend European politics.

What is already being called “the biggest global energy crisis in history” could have still more drastic consequences, and the EU is particularly exposed, with most of its major economies significantly more dependent on fossil fuel imports than the UK. European Central Bank President Christine Lagarde last month described the long-term effects for Europe as “probably beyond what we can imagine at the moment”.

Little wonder, then, that the EU has convened the dreaded European “working group”. EU Energy and Housing Commissioner Dan Jørgensen said on Friday that the bloc is exploring “all possibilities” to deal with a “long-lasting” shock, in which “energy prices will be higher for a very long time.” Jørgensen mentioned fuel rationing and releasing emergency oil reserves as potential steps to mitigate the crisis; fuel rationing has already been introduced in Slovenia, while fuel restrictions have been issued at four Italian airports.

The danger that similar steps become necessary throughout Europe calls for the kind of decisive action that the EU’s tortuous decision-making process cannot provide. Worse still, the Brussels bureaucracy hinders rapid action by individual member states through its overriding urge to protect the single market. Brussels is busy trying to tear down nationalist measures by Hungary and Slovakia — two EU nations still importing large quantities of Russian oil and gas — to maintain lower prices for domestic consumers by charging foreigners more to refuel at gasoline stations.

Calculating that they may end up carrying the can for the coming crisis, EU leaders are engaged in a desperate scramble to pin the blame on Donald Trump. Yet responsibility stretches back over successive generations of politicians who have ignored national and continental strategic realities in favor of ideological measures that never allowed for a world of geopolitical instability.

Calls for new European fossil fuel developments — most notably Norway’s desire to tap further oil and gas reserves in the Arctic — continue to be scuppered by climate-based opposition. The EU’s moratorium on Arctic oil and gas extraction was described last month by a Norwegian energy executive as “reduc[ing] Europe’s security of supply”, yet climate activists are now decrying attempts by the energy lobby to “scare European policymakers”. The planned phase-out of other fossil fuels is also being called into question: analysts in countries that still rely on coal, such as the Czech Republic, are arguing for a pause in the pending closure of mines.

The rejection of sovereign European fossil fuel enterprises leaves the EU sorely exposed to global price swings. This is not helped by the bloc’s attempt to cut off Russian energy supplies — a U-turn in policy that rested upon an assumed abundance of supply for the global market and, in particular, upon security of LNG supply from the United States, which may prove a less reliable seller in the event of a full-blown global energy crisis.

Certain EU countries are increasingly vocal about what they see as the insanity of refusing to do business with the energy mega-producer on their doorstep. Slovak Prime Minister Robert Fico on Saturday described the EU as a “suicide ship” when it comes to energy policy, calling for the lifting of sanctions on Russian energy “to save citizens from the ideological blindness and incompetence of the European Commission”. Hungary’s Viktor Orbán echoed Fico’s comments, while Belgian Prime Minister Bart De Wever described normalization of relations with Moscow as “common sense… In private, European leaders tell me I am right, but no one dares say it out loud.”

Germany, meanwhile, is regretting past folly of another kind. Late last month, its Energy Minister described the country’s turn away from nuclear energy as a “huge mistake” given the looming energy crisis.

Recognition of these missteps will do little to mitigate the impacts of coming fuel shortages and a potential German industrial crash sending shockwaves throughout the European economy. Whether or not the bloc is capable of retracing its steps to configure a more sovereign and secure future energy policy, an Easter of penitence for EU leaders foreshadows hard times ahead.
