The debate surrounding Germany’s Gebäudeenergiegesetz (GEG), or Building Energy Act, is intensifying, pitting the ruling SPD party against opposition factions and raising critical questions about the government’s climate strategy and its potential impact on citizens. At the heart of the dispute lies a contentious provision mandating that new heating systems utilize at least 65% renewable energy sources.
SPD energy policy spokesperson Nina Scheer has forcefully defended the 65% quota, arguing that any attempt to dismantle it requires a viable and equally secure, clean and affordable alternative – alternatives, she insists, are currently unavailable. Her comments to “Bild” newspaper underscore the party’s unwavering commitment to the provision, particularly in the wake of the 2022 energy price crisis when Germany’s reliance on fossil fuels exposed significant economic vulnerabilities and susceptibility to external pressure. Environment Minister Carsten Schneider (SPD) has echoed this stance.
The current legislative framework is proving ambiguous. While the coalition agreement pledged to “abolish” the existing heating law and introduce a more technologically open, flexible and simpler GEG, it also stipulated that CO2 reduction should be the primary metric for guiding policy and promised continued subsidies for renovations and heating systems. This apparent contradiction fuels accusations of policy incoherence and uncertainty.
However, the conservative CDU/CSU alliance is pushing for the complete abolition of the 65% renewable energy quota. Andreas Lenz, energy policy spokesperson for the CDU/CSU parliamentary group, characterized the regulation as “inappropriate” and called for its removal, reflecting concerns voiced by the Economics Ministry. Lenz’s argument centers on streamlining the process, accusing the current system of being overly complex and bureaucratic. He advocates for a “reliable framework” for citizens free from “prohibitions and constraints”. This sentiment is shared by Andreas Jung, CDU’s Deputy Chairman, who emphasized that while climate targets remain, the “traffic light” government’s heating law must be scrapped as agreed in the coalition agreement.
The escalating disagreement highlights a deeper fault line within German politics concerning the balance between ambitious climate goals and the practical realities of implementation. The country’s building sector consistently fails to meet its targets set out in the Federal Climate Protection Act and the looming threat of EU “Effort Sharing Regulation” penalties – levied for insufficient emissions reductions – adds further pressure. The core question facing policymakers now is whether a rigid, often unpopular, regulatory approach is the most effective way to achieve Germany’s climate ambitions, or whether a more flexible and locally-driven strategy, even if potentially less stringent, is required to secure political and public support for the necessary transition. The debate risks further delaying meaningful progress on decarbonizing Germany’s buildings and jeopardizing its international climate commitments.
