Cooling down is catching on. As incomes rise and populations grow, especially in the world’s hotter regions, the use of air conditioners is becoming increasingly common. In fact, the use of air conditioners and electric fans already accounts for about a fifth of the total electricity in buildings around the world – or 10% of all global electricity consumption. Over the next three decades, the use of ACs is set to soar, becoming one of the top drivers of global electricity demand. A new analysis by the International Energy Agency shows how new standards can help the world avoid facing such a “cold crunch” by helping improve efficiency while also staying cool.
