Will Data Centers Threaten California’s Water? It’s Complicated.

The explosive growth in data centers is fueling concerns in California, as well as across the country, about water and energy use. Some have gone as far as to propose a water usage fee on data centers. However, others argue that data center water use is just a drop in the bucket compared to other uses or that most data centers are moving toward less water-intensive practices, such as reusing water in closed-loop systems.

To help us understand what we do and don’t know about California data centers and water use, we spoke with Dr. Marie Grimm, an environmental policy research fellow at UC Berkeley’s Center for Law, Energy, & the Environment, about their new report “Regulating Data Center Water Use in California.”
