The extreme heatwave across Europe and the United States has intensified, driving historic power demand and a massive global market for cooling technology. In the US, a persistent heat dome affects over 40 million people, prompting Entergy Texas to allocate an additional $500,000 to its Power-to-Care program for vulnerable customers. Central air conditioner shipments in the US rose 26.8 percent in June compared to the previous year, marking five consecutive months of growth.

In Europe, air conditioning installation requests have surged significantly: Germany reported a 152 percent increase, the United Kingdom 150 percent, the Netherlands 114 percent, and France 90 percent. This demand has fueled a rise in exports from Chinese manufacturers, such as Haier and Midea, with exports to the EU reaching $3.76 billion in the first half of 2026, a 43 percent increase from the previous year. 

In Italy, rising temperatures have triggered a shift in domestic habits. Despite historical cultural resistance due to health concerns like ‘colpo d’aria’ (blast of air), the percentage of Italian households with air-conditioning rose from under 30 percent in 2013 to 56 percent in 2024, following the hottest August on record.

In the UK, businesses are adapting to rising temperatures; the Q2 Barclays Business Prosperity Index indicates 60% of firms have taken steps to counter heat, with 37% boosting investment in cooling and HVAC systems. Additionally, London has released the Cooling Roadmap for London (CRL) to address the urban heat island effect. The plan aims to reduce energy demand through sustainable, efficient, and equitable cooling (SEC) measures, prioritizing social housing and healthcare to mitigate cooling poverty.
