A warming world is gearing up to install 1.6 billion new air conditioners by 2050, which will require an additional 4.8 trillion kWhs of electricity every year, mostly during peak energy demand in the hottest part of the day. But thermal energy storage can offset that peak by using off-peak energy during the night to make cold water, or even ice, and storing inside energy storage tanks. The stored ice is then used to cool the building’s occupants the next day.
