It is true that the usage of AI employs large amounts of water and energy to run. One of the sources given states, “A medium-sized data centre (15 megawatts (MW)) uses as much water as three average-sized hospitals, or more than two 18-hole golf courses,” and “This has been the source of considerable controversy in areas of water stress and highlights the importance of understanding how data centres use water.” These two points alone could prove to someone that training and using AI is wasteful, considering the numerous other outlets water resources could go to. This same source also includes how “Google and Microsoft are leading in renewable energy, but even they are secretive about their water resource management.” Even though two large companies have focused efforts on renewable energy, they are still not being transparent about their water usage–one could ask why. “Making AI Less ‘Thirsty': Uncovering and Addressing the Secret Water Footprint of AI Models”, a paper conducted by multiple engineering researchers and professors, was published in Cornell University Tech’s scholarly research archive with notable points. The paper reads, “...the global AI demand is projected to account for 4.2 – 6.6 billion cubic meters of water withdrawal in 2027, which is more than the total annual water withdrawal of 4 – 6 Denmark or half of the United Kingdom. This is concerning, as freshwater scarcity has become one of the [world’s] most pressing challenges.” In addition, “ Even excluding the water usage in leased third-party colocation facilities, one technology company’s self-owned data centers alone directly withdrew 29 billion liters and consumed (i.e., evaporated) more than 23 billion liters of freshwater for on-site cooling in 2023…” One company using more than 50 million liters of water, and about half “evaporating”, many may say, is considered pretty wasteful.
The authors conclude by writing, “AI’s water footprint can no longer stay under the radar and must be addressed as a priority as part of the collective efforts to combat global water challenges.” So, in regards to this claim, is AI wasting water? There is evidence proving that AI usage does use an exponential amount of water, which is fair to be defined as too much. Although claiming whether or not the usage of AI is specifically “wasting water” does leave out complexities and other angles, organizations, tech companies, and governments will take on AI’s usage and its positives.
From the UN Environment Programme on how AI is harming the environment:
“They [AI data centers] rely on critical minerals and rare elements, which are often mined unsustainably. And they use massive amounts of electricity, spurring the emission of planet-warming greenhouse gases.”
“Data centres produce electronic waste, which often contains hazardous substances, like mercury and lead.”
From Better Planet Education:
“Every time you message ChatGPT, 4 grams of CO2 are emitted into the atmosphere as a result of the 30,000 GPUs (graphics processing units) operating constantly in order to keep the servers online. … it [ChatGPT] has an estimated 123.5 million users per day. That is 494 billion grams of CO2 released from just ChatGPT alone. To visualise that nauseating figure, that is equal to 2,090 average trips out in the car.”
From the Harvard Business Review:
1. "The generation of electricity, particularly through fossil fuel combustion, results in local air pollution, thermal pollution in water bodies, and the production of solid wastes, including even hazardous materials."
This claim is true when it says AI is harmful to the environment. This is clear with the increase in carbon emissions/pollution, mining of minerals, and the amount of electricity used. To move forward with AI, “Making AI Less ‘Thirsty': Uncovering and Addressing the Secret Water Footprint of AI Models”, “[Recommends] increased transparency and comprehensive reporting of AI’s water footprint, and highlight[ing] the necessity of holistically addressing the water footprint along with the carbon footprint to build truly sustainable AI.” It’s crucial to recognize the impacts of AI and acknowledge possible solutions to 'build sustainable AI’ if that’s even possible.
The Chief Digital Officer of the United Nations Environment Programme reminds us that, “There is still much we don’t know about the environmental impact of AI, but some of the data we do have is concerning.”
