The No Desert Data Center Coalition filed a lawsuit last week against Pima County in southern Arizona for approving a land sale and rezoning request from a data center developer — just the latest move in the battle over data centers amid water concerns in Arizona. … Local opposition to data centers in Tucson, a Democratic stronghold, Marana, a conservative-leaning district, and Chandler, a Republican suburb, suggests bipartisan consensus over concerns of water scarcity and rising energy costs. … Beale Infrastructure, the data center developer, said the data centers will be air-cooled instead of using millions of gallons of water to “wash” the heat away from servers. But the trade-off in this case is a massive energy draw in an already strained region.
