Europe is increasingly adopting air conditioning as severe heat waves become more frequent and intense due to global warming. Once considered an American luxury or a Mediterranean necessity, air conditioning is now becoming a common feature across the continent. Data from 2021 indicates that air conditioning uptake was already high in regions such as Veneto, with 70% penetration, and Sicily, with 62.4%. The shift reflects changing attitudes as Europeans face rising temperatures and heat-related mortality, which in some countries like France, surpasses deaths from shootings in the United States annually. Despite Europe’s abundant clean nuclear energy, debates continue, with some political groups opposing air conditioning even as it becomes essential for public health and comfort during heat waves.
