Utah’s fragile desert could feel like the Sahara if America’s biggest data center gets built

Plans for a celebrity-backed “hyperscale” data center in rural Utah, so massive that it would consume more than double the state’s current electricity use, have generated an intense public and political backlash in a state where the motto is “industry” and a Republican supermajority tends to be deferential to development. The project, brought by “Shark Tank” TV personality Kevin O’Leary, would span 40,000 acres, demand 9 gigawatts of power once completed, and raise the state’s carbon emissions by 64 percent, according to estimates. While its water needs remain unknown, the sprawling data center would neighbor the northernmost tip of the shrinking Great Salt Lake, which will likely hit a record-low elevation this year following an unprecedented dry winter. It could also create a massive heat island capable of devastating the area’s ecology, said Robert Davies, a physics professor at Utah State University. Davies estimated that the finished project would cover about as many square miles as Washington, D.C., making it the largest data center on the planet, and that it could produce enough heat to spike nighttime temperatures by as much as 28 degrees Fahrenheit in the high-desert valley. “I suspected it would not be good,” Davies said. “What I’ve found is, it’s so much worse than I even thought it would be.” News of the proposed data complex, dubbed the Stratos Project, became public in April after the three commissioners of Box Elder County, the mostly agricultural community that would host it, approved the project. They pointed to the project’s approval by more powerful state agencies and asserted that stopping it was out of their hands, while refusing to hear comments from more than 1,000 people who showed up to share their concerns. Utah Governor Spencer Cox, a Republican, has since walked back some of his full-throated support. “Many are asking questions about water, air quality, energy, land use, and the long-term impact on rural Utah,” Cox wrote in a thread
