Germany's AI Data Center Push Collides With EU Climate Rules
WIRED reports that the German government's plan to double the country's data center fleet and quadruple AI compute by 2030 is running into its climate commitments, including the EU's target of cutting greenhouse gas emissions 55 percent by the end of the decade. The previous administration's 2023 Energy Efficiency Act required new data centers to recycle part of their waste heat, ideally into municipal heating systems, but in June Berlin walked the rules back a month before they were due to take effect. Under an amended bill due before parliament imminently, operators would only have to assess whether heat reuse is technically and economically feasible, not carry it out.
The amendment is intended to make Germany more attractive for data center investment and reduce dependence on US AI access, but critics including former energy official Patrick Graichen say climate targets are being sacrificed and warn of public backlash.
Earlier this year, the German government laid out an ambitious plan: By 2030, it would double the scale of the country’s data center fleet, and quadruple the amount of compute available for running artificial intelligence models. The idea was to minimize Germany’s dependence on the United States for access to AI—a point of concern across Europe—and boost its faltering economy.
However, Germany has found that its AI ambitions are butting up against its climate commitments. EU member states have committed to cutting greenhouse gas emissions by 55 percent by the end of the decade. But policies meant to help meet that target are interfering with attempts to trigger a data center building frenzy.
As part of its broader climate commitments, the previous German administration voted through the Energy Efficiency Act in 2023. Among other things, it required all new data centers to recycle a portion of the waste heat generated by their computer equipment, ideally into nearby municipal heating systems. It seemed like a no-brainer, says Patrick Graichen, who served as a senior official at Germany’s Ministry for Economic Affairs and Energy at the time, before resigning over cronyism allegations.
