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 itโ€™s finally time to buy an air conditioner, you're far from alone.

The AC culture wars may be solved by advances in environmentally friendly technology.

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 2ยฐ C above preindustrial levels.

โ€œWe will need more cooling to protect peopleโ€, says Miranda, a senior lecturer in engineering and carbon reduction manager at the university. โ€œThe question is how to provide it in a way that is efficient, equitable, and smart. Not by panic-buying inefficient, energy-intensive portable ACs.โ€
