When European households opened their electricity bills in late 2022, many could hardly believe their eyes. Prices had quadrupled in some areas, industrial plants were shutting down, and the promise of cheap, clean, renewable energy seemed like a distant memory. What citizens across France, Belgium, and beyond didn’t realise was that they were paying the price for Germany’s ambitious energy experiment. This experiment would cost over a trillion euros and fundamentally reshape the European energy dynamics.
The story of Europe’s energy crisis is not simply one of Russian gas cut-offs or unfortunate timing. It is an analysis of how one country’s sustained policy commitment to phasing out nuclear power contributed to significant cost transmission eIects across an integrated continental electricity market, with French consumers bearing much of the burden despite their own country’s successful low-carbon nuclear strategy.
A Trillion-Euro Bet Gone Wrong
Germany’s Energiewende, or “energy transition,” was supposed to be a model for the world. Launched with great fanfare, the policy aimed to phase out both nuclear power and fossil fuels, replacing them with wind and solar energy. The numbers, however, tell a different story. Conservative estimates put the total cost at over one trillion euros, with more than 520 billion dedicated to the electricity sector alone. 1To put this in perspective, that’s more than the entire GDP of many European Union member states.
What did Germany get for this massive investment? Not energy security, not environmental leadership, and certainly not the stable, affordable electricity prices that were promised. Instead, the country found itself more dependent on fossil fuels than ever before, with carbon emissions remaining stubbornly high and electricity prices volatile.
A fair assessment of the Energiewende must also account for its less visible benefits. Germany’s renewable buildout supported an estimated 300,000+ jobs in the wind and solar sectors by 20222, and its large-scale deployment contributed meaningfully to the global learning curve that has driven solar costs down by over 90% since 2010. The sunk costs of France’s own nuclear program, including EDF’s accumulated debt and the estimated 50–100 billion euro Grand Carénage maintenance program, similarly complicate any straightforward cost comparison between the two models. None of this negates the transmission of costs to French consumers and industries documented in this paper, but it situates the Energiewende as a policy with real trade-offs rather than a straightforward failure.
The most striking contradiction emerged in 20233, when Germany shut down its last three nuclear reactors, representing approximately 4 gigawatts of reliable, clean power generation. This wasn’t a decision driven by safety concerns or economic necessity. Germany’s nuclear plants had operated safely for decades with minimal carbon footprint. Rather, it was a political choice made in the aftermath of Japan’s Fukushima disaster in 2011, when Chancellor Angela Merkel announced a complete nuclear phase-out to appease public fears.
The Persistence of Coal in Germany’s Energy Mix
Here’s where the story takes an ironic turn. While German politicians and environmental advocates were busy condemning French nuclear power as dangerous and outdated, Germany quietly reopened, extended, or increased capacity at 27 coal-fired power plants between 2020 and 20234. Twenty-seven coal plants came back online or expanded operations during the same period, a development that sits in tension with the stated environmental objectives of the Energiewende, and one that received comparatively limited attention in mainstream energy commentary.
Take the Datteln 4 hard coal plant, one of Europe’s newest and largest coal facilities, which came online in 2020 with 1,100 megawatts of capacity. That’s the same year Germany was demanding stricter EU emissions regulations from its neighbours.
The environmental consequences are stark. Coal plants emit around 820 grams of CO₂ per kilowatt-hour, while nuclear power produces only 12 grams across its entire lifecycle. Every hour of German coal power that could have been replaced by the nuclear capacity they shut down means roughly 800 additional tons of carbon dioxide pumped into Europe’s atmosphere. To understand what Germany’s nuclear phase-out actually cost the climate, it helps to work through a simple counterfactual. The three reactors shut down in April 2023 represented approximately 4 GW of capacity, which, at a conservative 85% capacity factor, would have generated around 30 TWh of low-carbon electricity per year. Electricity that, in practice, was largely replaced by coal. Given the lifecycle emissions differential between coal (820 gCO₂/kWh) and nuclear (12 gCO₂/kWh, per IPCC assessments), that substitution alone implies roughly 24 million additional tonnes of CO₂ per year. Extended to the broader capacity reductions across 2022–2023 and the higher coal dispatch volumes documented in German grid data (Bundesnetzagentur, 2023), the cumulative estimate rises to 40–50 million tonnes, an indicative upper bound, but one that reveals the scale of the climate cost embedded in a policy presented, above all else, as an environmental imperative.
Despite investing over half a trillion euros in renewable infrastructure, German electricity generation still emits 381 grams of CO₂ per kilowatt-hour. Compare that to France’s 56 grams per kilowatt-hour, achieved through its nuclear fleet. Germany’s emissions intensity is nearly seven times higher than that of its neighbour, despite all the rhetoric about climate leadership.
How French Households Ended Up Paying German Prices
The mechanism through which Germany’s energy choices impacted French consumers is complex but crucial to understand. It centres on something called the “merit order” system, which governs how electricity is priced across Europe’s integrated market.
In theory, the merit order makes economic sense: power plants bid into the market based on their operating costs, and the most expensive plant needed at any given moment sets the price for everyone. This was supposed to reward efficient generators and encourage competition. In practice, it became a tool for exporting Germany’s energy costs to its neighbours.
When German renewable output is high: when the wind is blowing, and the sun is shining, then the market floods with zero-cost electricity, driving prices down or even negative. This sounds great, but it devastates the economics of French nuclear plants that can’t quickly power down and end up earning nothing or even losing money during these periods. In the other hand, when German renewable output drops, gas-fired plants set the price at elevated levels reflecting volatile fossil fuel costs. Everyone pays these high prices, including French consumers whose nuclear plants could supply the same electricity at a fraction of the cost.
The numbers tell the story. French wholesale electricity prices averaged around 32 €/MWh in 2020, consistent with a decade of relative price stability (2010–2020 average: 42 €/MWh)5. A first upward inflexion occurred in 2021, with prices reaching 109 €/MWh, just before the Russian invasion of Ukraine, and followed by a peak of 276 €/MWh in 2022. This multi-year series suggests that the price shock predates the geopolitical crisis and is consistent with a structural shift in European market dynamics. That’s a 763% increase in just two years.
German officials and media attributed price increases primarily to the Russian gas crisis following the Ukraine invasion. The data, however, calls for a more disaggregated reading. Prices began climbing sharply in 2021, a full year before the invasion, suggesting that structural factors were already at work. That said, attributing the full magnitude of the 2022 spike to German policy choices alone would be an overstatement. ACER’s Market Monitoring Reports confirm that gas prices were the dominant driver of marginal electricity costs across Europe during peak periods. Compounding this, France lost approximately 50% of its nuclear capacity in 2022 due to stress-corrosion issues across the EDF fleet, dramatically increasing its import dependence at the worst possible moment. The most accurate reading is therefore one of compounding vulnerabilities: the removal of German dispatchable nuclear capacity eroded the structural buffer of the European market. Then, the gas shock delivered the acute blow, and France’s own availability crisis removed its ability to absorb it. Germany’s policy choices were a necessary, if not sufficient, condition for the scale of what followed.
The consequences for France’s position in the European electricity market were dramatic. For the first time since 1980, France became a net importer of electricity in 2022: importing 72.9 TWh while exporting only 56.5 TWh 6. To grasp how striking a reversal this was, consider that in 2021, France’s exports had still exceeded its imports by 44 TWh. At the height of the crisis in August 2022, nuclear availability had collapsed to roughly 35% of installed capacity, just 24 GW out of a total fleet of 61 GW, as stress corrosion checks grounded reactor after reactor. A country that had for decades been a structural exporter, underpinning grid stability across the continent, was suddenly competing on the same spot market as its neighbours to cover its own demand. EDF recorded a net loss of €17.9 billion for the year, forced to purchase electricity at crisis prices to compensate for output it could no longer generate itself.
For a typical French household consuming 4,500 kilowatt-hours annually, the price increase meant an additional 460 euros per year, or about 38 euros per month. Across France’s 29 million households, that’s 13-15 billion euros annually extracted from French families to pay for Germany’s policy choices. And these figures actually understate the true burden, because the French government implemented a “tariff shield” that capped price increases at 15%, with taxpayers absorbing the difference, costing an additional 45 billion euros between 2022 and 20247.
Disentangling the causal contributions to French price increases requires distinguishing between at least four concurrent factors. First, the European merit-order effect, by which German renewable intermittency creates systematic price volatility across coupled markets. Second, the gas price shock of 2021–2022, which was documented by ACER (Agency for the Cooperation of Energy Regulators), and the IEA (International Energy Agency), was the single largest driver of marginal electricity prices across Europe in peak periods. Third, the structural removal of German dispatchable nuclear capacity reduced the baseload buffer available to absorb demand spikes. Fourth, the French-specific availability crisis of 2022, in which stress corrosion issues idled approximately 50% of EDF’s nuclear fleet, dramatically increasing French import dependency at precisely the worst moment. A sensitivity analysis varying each factor’s weight suggests that while the gas shock accounts for the majority of the 2022 price spike, the structural factors, German nuclear exit and market design, explain a significant share of the elevated price floor observed both before and after the acute crisis period. Formal econometric modelling of these interactions remains an important avenue for future research
The Industrial Collapse
Beyond household bills, elevated electricity prices triggered an industrial crisis across France. Energy-intensive industries like aluminium, steel, chemicals, and glass manufacturing had located facilities in France precisely because of reliable, affordable nuclear electricity. Suddenly, they faced costs comparable to or exceeding those of global competitors.
French aluminium production declined by approximately 30% between 2021 and 2024. The Dunkirk aluminium smelter reduced capacity, while the Saint-Jean-de-Maurienne facility faced closure threats. Steel production similarly contracted, with ArcelorMittal idling blast furnaces at French sites while maintaining operations in countries with lower energy costs. Chemical producers began relocating capacity outside France and Europe entirely, often to regions with higher carbon emissions, perversely increasing global pollution while destroying French industrial capacity. 8
Each manufacturing job supports roughly three to four additional positions in supply chains and local services. The contraction in energy-intensive industries triggered broader deindustrialisation in affected regions. Conservative estimates suggest 40,000- 60,000 French industrial jobs were lost between 2021 and 2024,9 partly due to electricity price increases stemming from European market integration and German policy transmission.
Meanwhile, Germany announced a 200 billion euro energy price support package for its own industries in 2022, using state resources to shield German companies from the very costs that German policies had created. French industries, constrained by tighter fiscal limits, absorbed the full impact. This reveals another dimension of how the system works: imposing costs on all participants while protecting specifically German interests.
Lobbying Dynamics in EU Energy Policy
Germany’s impact on French energy sovereignty extends beyond market mechanisms into direct political lobbying within European Union institutions. German environmental foundations closely aligned with government policy spent an estimated 150-200 million euros between 2015 and 2023 on anti-nuclear advocacy targeting EU policymakers.10
Organisations like the Heinrich Böll Foundation and Rosa Luxemburg Foundation established permanent Brussels offices specifically to influence energy policy against nuclear power. These groups employed sophisticated tactics beyond simple opposition. They funded ostensibly independent research institutes producing studies questioning nuclear economics and safety. They organised strategic litigation challenging EU approvals for nuclear projects. They cultivated relationships with Commission officials and European Parliament members. Notably, nuclear opposition was systematically framed in environmental and safety terms, a rhetorical alignment that, whether intentional or not, served to reinforce the political palatability of anti-nuclear positions while making it more difficult to assess their potential economic motivations, including the protection of German renewable energy investments from nuclear competition.
The lobbying campaign achieved significant victories. Germany successfully delayed nuclear power’s inclusion in the EU Taxonomy for Sustainable Activities for years, preventing French nuclear projects from accessing green financing on equal terms with German wind and solar installations. When nuclear was finally included in 2022 following intense French pressure, Germany ensured onerous conditions regarding waste management that effectively discriminated against nuclear compared to lenient treatment for German gas infrastructure.
This asymmetry is analytically significant. Germany lobbied for natural gas to be classified as a “bridge fuel” worthy of green investment while simultaneously opposing nuclear power’s inclusion in sustainable activities. Gas gets a green label; nuclear doesn’t. This double standard allowed Germany to build gas infrastructure with EU climate funds while blocking French nuclear projects from similar financing.
Aggregating the Costs: A Cross-Impact Assessment
Calculating the comprehensive cost that Germany’s energy transition has imposed on France requires aggregating multiple impacts. Direct household electricity cost increases approximately 13-15 billion euros annually at current prices, plus 45 billion euros in government subsidies across 2022-2024. 11Industrial excess costs conservatively reach 8-12 billion euros annually for energy-intensive sectors alone. France’s state-owned utility EDF suffered a financial crisis, exacerbated by having to purchase electricity at inflated European prices while selling at regulated domestic rates, costing the company approximately 29 billion euros by mid-2023.
Germany’s energy policy imposed costs on France totalling 80-120 billion euros across 2021-2024: an average of 20-30 billion euros per year. For context, this exceeds France’s entire annual defence budget and represents approximately one percent of French GDP transferred to cover German energy policy consequences. If elevated prices persist, cumulative costs could reach 200-300 billion euros by 2030.
If these estimates are robust, the implied cost transfer would represent one of the most significant unilateral economic spillovers between European nations in the post-war period. One that emerged not through deliberate negotiation but through the interaction of national policy choices with a shared market architecture that was not designed to account for such asymmetric externalities.
Regional Reactions and the Path Forward
The recognition of this problem is spreading across European energy policy circles. Multiple EU member states, including France, Poland, Hungary, and the Czech Republic, have expressed growing dissatisfaction with current market designs. The question is no longer whether the current system is sustainable; clearly, it isn’t, but what alternative arrangements could preserve beneficial cooperation while preventing cost manipulation.
There are some promising signs. Other countries are reconsidering nuclear power despite German opposition. Poland announced plans for six nuclear reactors. The Czech Republic is expanding its nuclear fleet. Even the United Kingdom is developing new reactor designs. These nations recognise what France knew five decades ago: nuclear power provides reliable, low-carbon electricity at stable costs.
The global nuclear renaissance, accelerating across Asia and attracting renewed interest in the United States, vindicates France’s commitment to the technology. As Germany struggles with the contradictions of its renewable-fossil hybrid system, high costs, persistent emissions, continued coal dependence, and vulnerability to gas price shocks, France has the opportunity to demonstrate nuclear power’s superiority.
Success requires honest acknowledgement of recent challenges. France’s own nuclear fleet experienced maintenance issues in 2022 that reduced output and forced imports, an embarrassing reversal for a country that had been a net exporter for decades. But these were self-inflicted technical problems, not inherent flaws in nuclear technology. With proper investment in maintenance, workforce development, and new reactor construction, France can restore its energy independence.
Media Narratives and Hidden Agendas
The way this story has been covered reveals interesting biases. German media largely blamed the energy crisis on Russian aggression and unfortunate circumstances, downplaying the role of domestic policy choices. French media focused on technical failures at EDF and government mismanagement, often missing the broader European dimension. International coverage emphasised the geopolitical drama of Russian gas while treating Germany’s green transition as fundamentally well-intentioned, if perhaps overly ambitious.
What’s missing from much of this coverage is the systematic nature of how Germany’s choices imposed costs on neighbours. The merit order system, the lobbying against nuclear in EU forums, the reopening of coal plants while preaching environmental virtue, and the preferential treatment for gas infrastructure. These aren’t isolated incidents but pieces of a coherent pattern. Germany pursued its energy transition with determination, leveraging its political weight within EU institutions to shape regulatory frameworks that were broadly consistent with its domestic policy objectives, with the consequence, documented here, of externalising a share of the associated costs to neighbouring economies.
Some might argue this simply reflects normal politics, with each country advocating for its interests. But there’s a difference between legitimate advocacy and systematic manipulation of shared institutions. When a country’s influence over shared regulatory frameworks produces systematic cost asymmetries that fall disproportionately on neighbouring economies, the legitimacy of those frameworks warrants scrutiny. When stated environmental objectives: reducing emissions, accelerating the clean energy transition, diverge materially from observed outcomes, including increased coal dispatch and higher grid-level carbon intensity, that divergence merits rigorous, evidence-based analysis rather than rhetorical alignment alone.
