As artificial intelligence is increasingly developing and data centres are erected to further this tech, it’s becoming clear that AI has a water usage problem.
Microsoft’s latest sustainability report revealed that the software giant’s water usage saw a tremendous spike between 2021 and 2022. In 2021, the company used up 4,772,890 cubic meters of water. In 2022 that went up to 6,399,415—which is around a 30 percent increase from one year to the next. That’s almost 1.7 billion gallons of water in just one year, which is enough to fill more than 2,000 Olympic-sized swimming pools.
Why did Microsoft draw so much freaking water? Data centres that run AI supercomputers are hot. Equipment heats up, and if a centre overheats, those computers can shut down. The increase in water use is directly tied to the company’s investment and development of AI. Microsoft has backed OpenAI, which has a data centre in Des Moines, Iowa. During the summer months, the centre has to use a ton of water to keep equipment cool, especially as Iowa experiences rising temperatures due to climate change.
The water is drawn from nearby watersheds including the Des Moines and Raccoon rivers to cool the supercomputer that develops AI systems, the Associated Press reported. However, local waterways also provide drinking water for nearby communities. The volume used by the data centres has become a concern for the local utility company, West Des Moines Water Works.
A document from the utility dated April 2022 outlined that officials and the utility will only “consider future data centre projects beyond Microsoft Data Center Project Ginger East and West” unless the new projects can significantly lower their water usage. “This approach to resource conservation will help preserve the water supply for current and future commercial and residential needs of West Des Moines,” the document read.
Google, another tech giant that has heavily invested in AI products, has also seen a spike in water usage. An environmental report released this July outlined that the company’s water usage increased about 20% from 2021 to 2022. “We’re working to address the impact of our water consumption through our climate-conscious data centre cooling approach and water stewardship strategy,” a spokesperson told Gizmodo in an email this July.
As the planet becomes warmer, it may become harder for large tech companies to cool facilities. Many data centres are in cooler locations like the Pacific Northwest and states like Iowa in the upper Midwest, but neither location has been spared from heat waves.
Other tech companies have experienced challenges with keeping their centres online during especially hot weather. Last September, equipment at then Twitter’s data centre in Sacramento shut down during a heat wave. Increased instances of heat waves due to the climate crisis have also plagued data centres overseas. Last July, Google and Oracle’s London-based data centres went offline as England baked through sky-high temperatures of over 40 degrees Celsius.
