As temperatures in France shattered records this week, soaring past 45°C in some regions, the country’s notorious air conditioning inequality has become a public health crisis. For the wealthy, homes and offices remain cool oases. For the working class, particularly in dense urban housing and care homes, the heat is unbearable and deadly. Heat-related deaths have already spiked, with authorities urging the use of public cooling centres — many of which are underfunded and overcrowded.
Meanwhile, across the Channel, the UK’s comparatively milder heatwave has drawn praise for its green grid response. National Grid reported record renewable generation, with wind and solar meeting over 70% of demand during peak afternoon hours. This has kept electricity prices relatively stable, even as cooling demand surged. Unlike France, where 37% of homes lack any air conditioning, the UK’s lower reliance on fossil fuels for power has shielded bill payers from the worst of price spikes.
But the contrast is stark. In Paris, workers in bakeries, construction, and transport are forced to choose between lost wages and dangerous conditions. Unions have demanded mandatory cooling breaks and compensation, but employers resist. In the UK, unions are similarly calling for stronger heat protections, though the government has so far refused to legislate maximum working temperatures.
This is not just a weather story. It is a story of inequality. In France, air conditioning remains a luxury good. In the UK, the problem is structural: poor insulation in homes and inadequate investment in public cooling infrastructure. Both nations face the same warming planet, but their ability to cope depends on wealth and political will.
The lesson is clear: the green grid is not a panacea. It helps keep bills down, but it does not cool the homes of the poor. As heatwaves become the new normal, governments must invest in affordable cooling and worker protections. Otherwise, the divide will only deepen.
