The German government is reportedly considering reactivating mothballed coal-fired power plants as the country’s energy crisis intensifies, a move that would reverse years of decarbonisation efforts. According to sources familiar with internal discussions, the Ministry for Economic Affairs and Climate Action has drawn up contingency plans to bring up to 10 gigawatts of coal capacity online by winter. This represents a stark admission that renewable expansion has failed to keep pace with demand, leaving Europe’s largest economy vulnerable to supply shocks.
The crisis stems from a perfect storm of factors. Russian natural gas flows via the Nord Stream pipeline have been reduced to 20% of capacity, following maintenance disputes and geopolitical tensions. Meanwhile, France’s nuclear fleet is operating at historic lows due to corrosion problems, reducing electricity exports to Germany. And a prolonged drought has lowered water levels on the Rhine, hampering coal and oil deliveries. The result has been wholesale electricity prices surging past €500 per megawatt-hour, more than ten times the average of the past decade.
“This is thermodynamics, not ideology,” said Dr. Helena Vance, Science & Climate Correspondent. “When you cannot generate enough electrons, you must source them from somewhere. Coal, for all its carbon baggage, remains dispatchable. The question is whether this is a temporary patch or a permanent scar on the energy transition.”
The return to coal would undo years of progress. Germany has historically been a leader in renewable energy, with wind and solar now accounting for over 40% of electricity generation. But the expansion of renewables has faltered. Bureaucratic hurdles, local opposition, and supply chain issues have delayed wind farm construction. Solar installations have grown, but not enough to compensate for the shortfall. The country had planned to phase out coal by 2030; this timeline now appears untenable.
The environmental cost is significant. Coal-fired power plants emit more than twice the carbon dioxide per kilowatt-hour compared to natural gas. Activating 10 GW of coal capacity could increase Germany’s annual CO2 emissions by up to 50 million tonnes, a 7% rise from 2021 levels. This would make it nearly impossible for Germany to meet its 2030 climate targets, which require a 65% reduction in emissions compared to 1990.
But the immediate threat is to energy security. Gas storage levels are at 65% capacity, below the government’s target of 80% by October. If Russian supplies are cut entirely, Germany could face a gas shortage of 20 billion cubic metres this winter. That would force rationing for industry and potentially households. The coal option is a hedge against that scenario.
Economically, the move is fraught with risk. Coal generation is expensive given current carbon prices, which have risen to €90 per tonne. The government may need to subsidise coal plants or temporarily suspend the carbon price to make them economical. Such steps would send confusing signals to investors in renewable energy and battery storage, sectors that require policy certainty.
“We are seeing the limits of a piecemeal approach,” said Dr. Vance. “Energy transitions are not linear. You cannot simply replace one fuel with another overnight. The system is teeming with interconnected parts: infrastructure, supply chains, storage, politics. Ignoring these feedback loops leads to crisis.”
The German dilemma highlights a broader tension across Europe. Several countries including Austria, the Netherlands, and the UK have also turned to coal or delayed coal phase-outs in response to the gas crisis. Yet the Continent’s long-term goal remains carbon neutrality by 2050. Short-term survival strategies could lock in fossil fuel dependencies for decades if not carefully managed.
For now, Germany’s government is walking a tightrope. It has approved emergency laws to reactivate coal plants, but insists these measures are temporary. Climate Minister Robert Habeck has stated that the coal revival is a “bitter but necessary” step to get through the winter. The hope is that accelerated renewable deployment and demand reduction measures can fill the gap by next year.
But hope is not a strategy. The physical reality is that every tonne of coal burned today adds to the atmospheric load of CO2, which remains for centuries. The urgency of the climate crisis demands that such measures be short-lived and accompanied by binding commitments to re-accelerate the green transition. As Dr. Vance concludes: “We are borrowing against the planet’s future to pay for today’s debts. That is a dangerous bet.”
