For example, ACs sold in Japan and the European Union are typically 25% more efficient than those sold in the United States and China. One crucial factor is that the efficiency of these new ACs can vary widely. Supplying power to these ACs comes with large costs and environmental implications. AC use is expected to be the second-largest source of global electricity demand growth after the industry sector, and the strongest driver for buildings by 2050. But as incomes and living standards improve in many developing countries, the growth in AC demand in hotter regions is set to soar. Using air conditioners and electric fans to stay cool already accounts for about a fifth of the total electricity used in buildings around the world – or 10% of all global electricity consumption today. The global stock of air conditioners in buildings will grow to 5.6 billion by 2050, up from 1.6 billion today – which amounts to 10 new ACs sold every second for the next 30 years, according to the report. Global energy demand from air conditioners is expected to triple by 2050, requiring new electricity capacity the equivalent to the combined electricity capacity of the United States, the EU and Japan today.

The growing use of air conditioners in homes and offices around the world will be one of the top drivers of global electricity demand over the next three decades, according to new analysis by the International Energy Agency that stresses the urgent need for policy action to improve cooling efficiency.Ī new IEA report – “ The Future of Cooling” – shows that without new efficiency standards the world will be facing a “cold crunch” from the growth in cooling demand in coming decades.
