UK faces choice between energy-hungry AC and passive cooling solutions as heatwaves intensify

Crisp on the outside, thoughtful on the inside. A keeper.
Summary
The UK faces a critical choice in responding to rising temperatures from climate change. Rather than defaulting to energy-intensive air conditioning, which would create costly, unequal, and unsustainable outcomes, the article advocates for passive cooling solutions. Research surveying 1,600 UK households found two-thirds used fans in summer 2022 and one in five used AC, with most AC units purchased after that year's record 40°C heatwave. The article argues for redesigning homes, streets, and daily routines to stay cool naturally through better insulation, shading, green spaces, and behavioral changes.
Key quotes
· 4 pulledIf the UK and similar countries respond to hotter summers simply by installing more AC, they risk creating a costly, energy-hungry and more unequal future.
But there's a cooler, smarter way forward.
Colleagues and I have surveyed more than 1,600 households across the UK and found that two-thirds used fans in the summer of 2022, and one in five used air conditioning.
The vast majority of those AC units were bought during or after that year's 40°C heatwave – showing how extreme events drive technology adoption.
