A growing number of British households are turning to air conditioning as the country experiences hotter summers. An estimated 4 million homes in the UK now have air conditioning, double the figure from three years ago, according to an analysis reported by The Guardian. The surge in ownership comes as the UK's climate advisers warn that many homes will need active cooling to cope with future heatwaves.
Coverage comparison
The Guardian's reporting highlights both the personal and systemic dimensions of this trend. One article focuses on the broader statistics and expert commentary, another delves into individual stories, such as software developer Jon Connorton in Hampshire, who uses a portable unit only when necessary, powered by his solar panels. Both pieces emphasize that British homes, traditionally designed for cooler climates, are poorly adapted to extreme heat.
While the core facts are consistent across the two articles, they approach the topic slightly differently. The statistical piece places the rise in air conditioning within the context of climate change projections, while the feature-style article brings in practical advice on energy efficiency and passive cooling measures.
Key claims
The most commonly reported claim is that an estimated 4 million UK homes now have air conditioning, a figure that has doubled in three years. The Guardian notes that portable units with power ratings of about 1kW are slightly more common than built-in versions, which can consume up to 2.7kW, more than an electric oven.
Experts attribute the increase to more people working from home and rising summer temperatures, according to the reporting. The UK's hottest day on record was in July 2022, when temperatures hit 40C, and heatwaves are expected to exceed 40C in all parts of the UK by 2050, according to the Climate Change Committee. About nine in 10 UK homes are likely to overheat without adaptation.
Air conditioning is energy-intensive, accounting for about 4% of global greenhouse gas emissions. However, more efficient modern systems can use heat pumps, which are subsidised by the government for those replacing fossil fuel heating. Specifically, the government is offering a £2,500 grant to homeowners in England and Wales to replace a fossil fuel-based heating system with an air-to-air heat pump. These pumps move heat rather than generate it, and can produce about three units of cooling for every unit of electricity they use.
One significant challenge remains: air conditioning that runs purely on grid electricity won't be truly 'green' until the entire grid runs on renewable energy, as reported by The Guardian.
Perspectives
Pro-climate adaptation: The Climate Change Committee, the government's independent advisers, recommends installing air conditioning in all care homes and hospitals within the next decade, arguing that passive measures such as curtains and shading may not suffice.
Environmental caution: Researchers and experts, including Nicole Miranda from the University of Oxford, caution that air conditioning's energy demands could undermine net-zero efforts, and advocate for pairing units with solar power and using passive cooling first.
Consumer experience: As The Guardian's reporting shows, individuals like Jon Connorton feel a sense of guilt about using air conditioning, describing it as a 'luxury' that harms the environment, and they seek ways to minimize its impact.
