Germany lags in household air‑conditioner adoption amid rising heatwaves

Only about 6 % of German households have air‑conditioning systems, far below the roughly 80‑90 % penetration in the United States and Greece and well under the 50 % level in Spain. The low figure stems from decades‑long building designs that prioritized heating for cold winters rather than cooling for hot summers.

Demand for air‑conditioners in Germany has risen sharply, increasing by roughly 75 % between 2019 and 2024, according to analysis by the Boston Consulting Group. Nevertheless, many Germans still regard AC as a luxury rather than a necessity. Health experts warn that the growing frequency and intensity of heatwaves—linked to climate change—pose a serious public‑health risk, with thousands of heat‑related deaths recorded across Europe each year. Environmental groups caution that widespread AC use would raise electricity consumption and carbon emissions, urging alternatives such as better building insulation, shading, natural ventilation and urban greening.

The trend reflects a broader shift as European societies adjust to hotter summers while balancing energy and environmental concerns.
