Is an Air-Conditioning Revolution Coming to Europe?
If you're reading this while the blinds are drawn against yet another heat wave and wondering whether it’s finally time to buy an air conditioner
If you're reading this while the blinds are drawn against yet another heat wave and wondering whether it’s finally time to buy an air conditioner, you're far from alone. At the end of June, as temperatures climbed well above 40 degrees Celsius across Europe, shoppers in France literally forced their way into stores to snatch up portable fans and ACs before they sold out. Such scenes are likely to become more common. As the planet warms, the demand for cooling is rising worldwide. The International Energy Agency (IEA) predicts two-thirds of households could own an AC by 2050. Politicians are, of course, turning ACs into a weapon in their broader culture wars. Far-right figure Marine Le Pen pledged to roll out air-conditioning across France if her party comes to power, while the British Conservatives vowed to overturn net-zero rules that restrict AC installation in new builds.
On the left, the argument runs that air-conditioning would mainly benefit the rich and not those who need it most. It would also lock Europe into the same high-energy cooling spiral seen in the US and Asia. To date, only around 20 percent of Europeans have AC at home (and a mere 4 percent in the UK), compared with roughly 90 percent in the US, where electricity is considerably cheaper. In Europe, air-conditioning is no longer just about comfort. It helps adults stay productive through extreme heat, and children concentrate in poorly ventilated schools. It helps people nod off when the air is still stiflingly warm long after sunset. It can even save lives. One research group estimated that air-conditioning prevented nearly 200,000 premature deaths among people over 65 in 2019 alone. Europe is warming faster than any other continent, and countries that once had relatively mild summers are now experiencing increasingly frequent and intense heat waves.
Research by Nicole Miranda and her colleagues at the University of Oxford suggests that countries such as the UK, Switzerland, Norway, and Finland could see some of the largest relative increases in heat exposure and cooling demand if global warming reaches 2 degrees C above preindustrial levels. “We will need more cooling to protect people”, says Miranda, a senior lecturer in engineering and carbon reduction manager at the university. “The question is how to provide it in a way that is efficient, equitable, and smart. Not by panic-buying inefficient, energy-intensive portable ACs.” June’s record-breaking heat wave offered a glimpse of what lies ahead. In northern Europe, homes and offices built to retain heat during long winters turned into ovens. A recent report by the UK's Climate Change Committee warns that by mid-century, over 90 percent of existing homes could overheat during severe heat waves. Even further south, centuries-old architectural adaptations—such as thick stone walls, white-painted façades, blinds and small windows designed to block the sun—are reaching their limits.
