How much of a problem is AI’s water use?
“Protect our water,” “Water for people not AI,” “Don’t mess with our water,” declare protest signs from Texas to New Mexico to Arizona. Angered by water use, energy consumption and pollution, locals are increasingly protesting the rapid expansion of data centers in the United States as tech companies work to rapidly expand capacity for AI. Many data centers rely at least partly on water to absorb heat from air or surfaces, and then cause cooling as it evaporates, just like sweating keeps our bod
Get smart on it
AI data centers consume significant amounts of water for cooling their processors, which can reach extremely high internal temperatures. While data center water consumption currently represents less than 1 percent of the nation's total water usage, rapid expansion of AI infrastructure could substantially increase this figure, particularly straining water resources in drought-prone regions. Solutions exist to reduce AI's water footprint, including shifting to renewable energy sources, strategic placement of data centers in water-rich areas, and adoption of more efficient cooling technologies such as liquid cooling systems. Experts predict that combining these approaches could reduce AI's future water consumption by up to 86 percent.
