Experts say calculating exact resource use is difficult because operators report companywide figures, not site-specific data. A 1-gigawatt AI data center can consume up to 10 million gallons of water daily, according to UC Riverside professor Shaolei Ren, depending on cooling methods and hardware. Liquid cooling, used in modern AI systems like Nvidia’s Vera Rubin and AMD’s Helios, is more efficient than air cooling but still relies on external water for heat rejection, especially in hot climates.\n\nCompanies like Meta and SpaceX claim their facilities use minimal water, but local water allocations often exceed their stated peak usage. Meta’s 1-gigawatt Indiana data center, for example, may require up to 8 million gallons daily in extreme heat. Tech firms are investing in water treatment plants—Meta spent $100 million in Idaho—to recycle water, but challenges persist. Meanwhile, chipmakers like DeepX and SK Hynix are developing cooler processors to reduce cooling demands.","keyPoints":["Voters in 40 of 41 states approved ballot measures to restrict AI data centers over water and power concerns","AI data centers can use up to 10 million gallons of water daily, depending on cooling methods and location","Companies like Meta and SpaceX claim minimal water use but face local water allocation disputes"],"whyItMatters":"Public opposition to AI data centers could slow their expansion, forcing companies to invest in water recycling or alternative cooling.
