Berlin, 15 March 2025. The German government has signalled a potential reversal of its coal phase-out plan, a move that would mark a significant deviation from its climate commitments. Chancellor Friedrich Merz announced on Thursday that a temporary increase in coal-fired power generation is being considered to bridge the gap left by dwindling natural gas supplies and underperforming renewables. The decision comes as energy prices surge across Europe, with German wholesale electricity prices hitting €285 per megawatt-hour, a 40% increase since February.
This is not a policy shift but a crisis response. Germany’s Energiewende (energy transition) has been a global benchmark for renewable integration. Yet this winter, wind power generation has fallen 18% below the seasonal average due to a persistent high-pressure system over the North Sea. Solar output is similarly depressed. Simultaneously, French nuclear capacity remains constrained by maintenance outages and cooling water shortages in drought-affected rivers. The result is a perfect storm for Europe’s largest economy.
Data from the Fraunhofer Institute shows that coal plants, which accounted for 12% of Germany’s electricity in 2024, are being brought back to life. Units that were mothballed have been reactivated under emergency procedures. The Climate Ministry estimates that burning more coal for the next six months could add an extra 15 million tonnes of CO2 to the atmosphere. To put that in perspective, it is roughly equal to the annual emissions of Latvia.
The irony is not lost on climate scientists. Dr. Helena Vance notes: “Germany’s predicament illustrates the physical reality of energy transitions. Renewables are intermittent, storage is insufficient, and baseload power sources are being retired faster than alternatives can replace them. You cannot solve a winter energy crisis with solar panels and wind turbines alone unless grid-scale battery storage is operational, which it is not.”
This is a systems failure, not a technology failure. Germany has invested over €200 billion in renewables since 2010. Yet its grid relies heavily on Russian gas imports, which were cut by 80% following the Ukraine conflict. Liquified natural gas terminals are being built but are not yet operational. The coal U-turn is a direct consequence of geopolitical upheaval layered on top of structural energy vulnerabilities.
The emissions cost is clear. Germany’s legally binding climate targets require a 65% reduction in greenhouse gases by 2030 relative to 1990 levels. Current projections suggest the country will miss this target even without increased coal use. Each tonne of CO2 emitted now is a tonne that cannot be emitted later if the 1.5°C warming limit is to be respected. The global carbon budget is finite.
Yet the alternative is economic collapse. German industry, already battered by high energy costs, is facing shutdowns. The chemical sector alone employs 500,000 people and depends on stable electricity prices. A blackout scenario is no longer unthinkable. The government’s decision highlights the tension between long-term climate goals and short-term energy security.
What is the solution? Accelerated deployment of renewables combined with energy storage must take precedence. But this requires political will and capital. Germany has earmarked €12 billion for hydrogen projects, but green hydrogen remains a niche. In the meantime, the coal plants will burn, and the CO2 will accumulate.
This is not a story about German failure. It is a story about the physical constraints of energy transitions. The globe is warming, the biosphere is under strain, and technological solutions are not arriving fast enough. The planet does not negotiate.
Dr. Vance concludes: “We are in a race against time, and currently we are losing. Every decision to burn more fossil fuels is a decision to accelerate the collapse of the ecosystems we depend on. The urgency is calm, but it is absolute.”
As Germany turns back to coal, the world watches a stark lesson in the limits of political ambition when faced with thermodynamic reality.
