Residents in Texas to Arizona are protesting the rapid expansion of data centers, citing concerns over water use, energy consumption, and pollution. Protest signs read 'Protect our water' and 'Water for people not AI,' reflecting growing local frustration. Many data centers rely on water for cooling, using evaporation to absorb heat from processors, which can reach up to 176° Fahrenheit. While data centers consume significant energy, water use is more complex, with online claims ranging from 500 ml per query to assertions that AI's water issue is nonexistent. Experts say overall, data center water use is much less than that of agriculture and some manufacturing industries. Source: arstechnica
Recent studies estimate that data center cooling systems consumed 66 billion liters of water in 2023, less than 1 percent of the nation's total consumption. However, with the rapid buildout of AI data centers, this figure could rise significantly, especially in drought-prone areas like New Mexico and Arizona. Engineers suggest that efforts to replenish and restore natural water resources, along with renewable energy and better siting, could lead to net-zero water use for on-site cooling. Fengqi You of Cornell University notes that there are many good ideas to reduce the strain on local water resources. Source: arstechnica
Experts predict that AI data centers will use more water for cooling and generating fossil fuel-powered electricity as their numbers increase. A 2025 study projected that by 2030, US data centers could consume 731 billion to 1,125 billion liters annually. Solutions such as shifting to renewables, improving AI processor efficiency, and strategic siting could significantly curb AI's water use. You adds that data centers should be located in areas with ample renewable energy sources rather than water-stressed regions. Source: arstechnica
