Many AI data center facilities use evaporative cooling, which involves turning clean water into water vapor to carry heat away.

Data centers across the industry swallow 449 million gallons (1.7 billion liters) of water daily.

Morgan Stanley projected that annual water use for cooling and electricity generation by AI data centers could reach approximately 1,000 billion liters (one trillion liters) by 2028.

AI data centers use water primarily for cooling computer chips, which get hot and perform less efficiently when overheated.
