Energy Transition Under Fire: Can Europe Still Afford to Go Green?

European green transition and energy crisis coexistence 2026

One of the more counterintuitive developments of the Iran war energy crisis is that it has simultaneously strengthened and weakened the case for accelerating Europe's green energy transition. The strengthening argument is direct and powerful: every megawatt-hour of electricity generated by wind turbines or solar panels is one that does not require gas, oil, or any imported fuel.

Countries with the highest share of renewables in their electricity mix — Denmark, Germany, Spain — have been measurably more insulated from the current price spike than those still heavily dependent on gas-fired generation. The renewable energy sector has never been able to make its energy security argument as forcefully as in March 2026.

The weakening argument is more subtly structural. The geopolitical and economic disruption of the Iran crisis is absorbing enormous financial and political attention.

Finance ministers at the Eurogroup are focused on managing the immediate economic damage rather than financing long-term structural investment. The ReArm Europe defence spending surge is competing with green transition funding for fiscal space.

And within domestic political systems, the practical experience of high energy bills is generating some pushback against the elements of climate policy — carbon pricing, phase-out of gas heating, EV mandates — that were already generating political opposition. The EU's ability to hold its green transition course while simultaneously managing an acute energy crisis and a defence spending emergency will test the institutional coherence of its policy agenda in ways that comfortable conditions never do.

The answer will significantly determine whether Europe emerges from this period of turbulence with its climate leadership intact or diminished.
