Artificial intelligence is a game changer—and a water guzzler. “AI represents one of the most prominent and fastest-expanding workloads in data centers,” write researchers from the University of California, Riverside, and the University of Texas at Arlington in a recent paper.
They note that
        Alphabet’s
       Google,
        Microsoft,
       and
        Meta Platforms
       used more than two billion cubic gallons of fresh water to cool servers and produce electricity last year, more than twice Denmark’s annual use. Training OpenAI’s generative model, GPT-3, in Microsoft data centers consumes 5.4 million liters of water over two to four weeks, and needs the equivalent of some 17 fluid ounces for a conversation of 10 to 50 questions and answers. “These numbers may increase for the newly launched GPT-4 that reportedly has a substantially larger model size,” they say.
The big tech companies tout “water stewardship” and becoming “net water positive,” pledging to replenish more water than they use by 2030. That’s a lot of water. Google said that in 2022, water consumption at data centers and offices was 5.6 billion gallons—the equivalent of irrigating 37 Southwestern golf courses annually. Microsoft has said it is tackling its 6.4 billion cubic meters in two ways: reducing water-use intensity—the amount of water per megawatt of energy—and replenishing supplies in water-stressed regions. Maybe Big Tech should throw some AI at the problem.
