Can Europe Build Data Centers Without Giving Up Its Climate Goals?

Germany's commitment to climate goals has created a dilemma for the country's push into AI and data centers. The EU has pledged to reduce greenhouse gas emissions by 55 percent by the end of the decade, and this target has intersected with efforts to spur the growth of data centers, which are energy-intensive. Germany's previous administration passed the Energy Efficiency Act in 2023, which required new data centers to recycle a portion of waste heat generated by their equipment, preferably into nearby municipal heating systems.

This policy aimed to turn data centers into a source of clean heat. However, data center companies complained that the requirements made building in the country nearly impossible, leading to the cancellation of multiple data center projects. The German government has now amended the act, allowing developers to assess the feasibility of recycling waste heat rather than being obligated to do so.

While some industry officials argue that the heat offtake should be a default criterion for developers, others claim these obligations could be a barrier to entry. Critics accuse the government of sacrificing climate targets to capitalize on the AI wave, but data center developers assert that there are no technical reasons preventing the reuse of waste heat.

The amended act may attract data center developers to Germany due to its central location, but it could also lead to climate-focused activism similar to that seen in the US, potentially hindering the building frenzy.
