A bottle of water per email: the hidden environmental costs of using AI chatbots

Often, water systems are used to cool the equipment and keep it functioning. Water transports the heat generated in the data centers into cooling towers to help it escape the building, similar to how the human body uses sweat to keep cool, according to Shaolei Ren, an associate professor at UC Riverside.

After a lengthy court battle, the Oregonian newspaper forced Google to disclose how much its data centers were using in The Dalles, about 80 miles east of Portland; it turned out to be nearly a quarter of all the water available in the town, the documents revealed.

In July, Google released its most recent environmental report, showing its carbon emission footprint rose by 48 percent, largely due to AI and data centers. It also replenished only 18 percent of the water it consumed — a far cry from the 120 percent it has set as a goal by 2030. “Google has a long-standing commitment to sustainability, guided by our ambitious goals—which includes achieving net-zero emissions by 2030,” said Mara Harris, a spokesperson for Google.
