“Since the closure of the Strait of Hormuz, imported fossil fuels cost Europe an additional €127 billion without a single molecule of energy in addition,” von der Leyen said in a keynote at the WinWin Brussels Summit.

In April, about seven weeks into the war, the Commission put the extra cost at €24 billion (about $27 billion).

By late September, EU energy commissioner Dan Jørgensen said it had passed €100 billion (about $111 billion), similarly echoing our ninth-grade science class building and saying that the bloc hadn’t received “one extra molecule of gas or oil.” “When we import oil and gas, we risk importing the shocks and crises that come with them,” von der Leyen said at the keynote.

A fuel shortage years in the making After Russia invaded Ukraine in 2022, Moscow cut gas flows to the EU to a trickle, and governments scrambled to fill storage at record prices, with the bloc eventually vowing to wean itself off Russian energy.

As a result, Russia’s share of EU gas imports fell from about 45% before the invasion to about 13% in 2025.

In January, EU members adopted a ban ending Russian liquefied natural gas (LNG) imports by the end of this year and pipeline gas by autumn 2027.

But Europe largely replaced Russian gas with other imports, much of it LNG shipped from the U.S.

and the Middle East.

When the Iran war began, the EU still got 57% of its energy from imported fossil fuels.

The war then shut the Strait of Hormuz, the waterway that carried about one-fifth of the world’s traded oil.
