As of January 1, 2025, Ukraine has officially halted the transit of Russian gas, a significant escalation in the ongoing energy conflict stemming from Russia's invasion of Ukraine over two years ago. This decisive action has sent ripples through the European energy market, leading to a spike in gas prices and political outcry, particularly from nations that were reliant on Russian supplies.

European gas prices surged to a 15-month peak following Ukraine's decision, a move that Ukrainian President Volodymyr Zelenskyy labeled "one of Moscow's greatest defeats." The closure of the Ukrainian transit route will cost the Russian state-run firm Gazprom an estimated €6.3 billion in annual revenue, while Ukraine anticipates a loss of around $800 million in transit fees (source: VOA News).

This decision aligns with Europe’s ongoing efforts to reduce dependence on Russian energy, which has notably decreased from over 40% of EU gas needs in 2021 to approximately 19% by September 2024. Analysts indicate that Europe has made significant headway in diversifying its energy sources through increased imports of liquefied natural gas (LNG) from countries such as the United States and Norway (source: Le Monde).

However, the transition has not been devoid of challenges. While some countries, including Slovakia and Hungary, face increased energy costs, the EU has generally prepared for this shift. Energy analyst Thomas O'Donnell noted, "The rise in gas prices was all prepared for. It's basically all priced in," suggesting that the impact will vary across member states (source: VOA News).

In contrast, the move has affected non-EU member Moldova, heavily reliant on Russian gas, which is now facing critical energy shortages exacerbated by this decision. Consequently, neighboring Romania has been assisting Moldova amidst these concerns (source: Le Monde).

Zelenskyy viewed the end of cooperation with Moscow as not just a strategic military decision but a moral victory. Despite the plummet in Moscow's energy revenues, he has pointed out that many European leaders appear hesitant about finalizing their rift with Russian gas, worrying that a potential ceasefire might rekindle negotiations over gas imports (source: Le Monde).

The dynamic shifts within Europe’s energy supply chains reflect both a reckoning with past dependencies and a strategic pivot towards sustainable energy independence in light of ongoing geopolitical tensions. While some countries express frustration over Ukraine's energy policies, Zelenskyy's government asserts the necessity of such measures to weaken Russia economically and militarily (source: VOA News).
