Overview
- Only about six percent of German households have air conditioning, but consumer demand jumped sharply in recent years and surged again during the latest heat extremes.
- Temperatures that have produced so-called 'tropennächte' and 'wüstentage' have pushed people to buy portable and split units, creating local shortages and a scramble on resale markets.
- Eurostat data show EU energy used for cooling rose 15.3 percent in 2024, illustrating how more air conditioning increases electricity demand and can raise emissions if powered by fossil fuels.
- Household adoption is constrained by rental rules, retrofit costs and building norms built for a cooler climate, while studies link some AC use to health complaints and infrastructure failures have occurred in transport systems during past heatwaves.
- Policymakers and firms are weighing short-term fixes such as new gas capacity against cleaner options like heat-pump cooling, solar-powered units and district cooling, with analysts warning an aging population will widen demand unless alternatives scale up.
