AI data centers are driving up electricity and water use

In short: As AI grows, more data centers are being built, and many of them use so much electricity and water that they are sparking local and environmental concerns.

What's going on

Data centers are large buildings filled with computer servers (think of them as warehouses full of machines that run online services). The Verge reports that the data centers built to power today’s AI boom are pushing up electricity demand and, in some places, water use as well.

A single large AI data center can use as much electricity as about 100,000 homes. The biggest sites, around 600 megawatts or more, can be closer to the power use of 350,000 homes. By 2030, U.S. data centers could use about 12% of the country’s electricity, and their annual carbon dioxide emissions could reach 24 to 44 million metric tons, similar to adding 5 to 10 million cars to the road.

Water is another pressure point. Estimates in the reporting put annual data center water use at 731 to 1,125 million cubic meters, about what 6 to 10 million Americans use at home. In dry states like Arizona and Nevada, that can turn siting fights into water fights. Nearby residents also raise concerns about diesel backup generators and constant fan noise, especially when projects cluster near lower-income neighborhoods.

What to watch

Communities and lawmakers are increasingly pushing for stricter rules, like full public disclosures, limits on toxic chemicals, cleaner backup power, and fees that help pay for grid upgrades. Researchers also argue that where these centers are built matters, like placing them in areas with more wind power and more available water, and using more efficient cooling systems.
