Zoe Schlanger, writing for Quartz: In 2016, roughly 10% of the planet’s energy use went towards air conditioning. Figures vary wildly from country to country, though, and some of the hottest regions on Earth use the least A/C — for now. A new report from the International Energy Agency says that’s about to change. By 2050, the intergovernmental agency predicts, global energy use from A/Cs will triple, reaching a level equivalent to China’s total electricity demand today. The African continent is home to some of the hottest places on Earth, but fewer than 5% of people in most African nations own an air conditioner, and energy used for cooling comes to just 35 kWh per person living in the continent, according to the IEA. In India, where large parts of the country are hot all year round, people use an average of 70 kWh for cooling. Compared to nations where having an A/C is the norm, that’s almost nothing at all.
