July 2021 was officially the hottest month on record, globally, since these records have been kept. One can hardly be faulted for seeking out air conditioning. In fact, rising incomes in the developing world, even more than rising temperatures, are expected to cause AC use to triple by 2050. In 2016, electric fans and air conditioning accounted for nearly 10% of global electricity consumption. By 2050, that too may triple, putting increased pressure on often balky electricity grids. Even if the energy to power air conditioners comes from entirely renewable sources, AC units themselves leak hydrofluorocarbons which are greenhouse gases thousands of times more potent than carbon dioxide, making even hotter summers more likely. www.economist.com/graphic-detail/2021/08/10/demand-for-air-conditioning-is-set-to-surge-by-2050
