When Amazon proposed building its Project Blue data center in Tucson, Arizona, the company faced intense pushback. Residents raised concerns about the enormous amounts of water and electricity that the data center would need—two major ways such projects impact the environment, especially in a desert city. … A study published this week in the journal Nature Sustainability makes that connection even clearer. Led by researchers at Cornell University, the study analyzed the environmental impact that data centers could have in the U.S. as their growth continues, and created a state-by-state look at where those data centers should go to avoid the worst effects.
