Energy demand from air conditioning worldwide is projected to triple to 6,200 terawatt-hours by 2050, which is the equivalent of a quarter of the total annual electricity consumption today. This is one reason many are trying to make more efficient air conditioning tech, as the current units have not seen the massive leaps in efficiency seen in other electrical technology like solar panels, batteries, and electric vehicles, and with billions of new air conditioners awaiting purchase in the decades to come, the sooner the better. In Los Angeles alone, rising temperatures could increase peak summertime electricity demand by 51 percent by 2060 under the worst case scenario. India is projected to install 1.1 billion AC units by 2050, which would make air conditioning account for 45 percent of peak electricity demand in the nation compared to 10 percent today.
