Data centers' water usage in Arizona is a contentious issue, but an environmental analyst argues the concerns are overblown. Andy Masley says most of the water "used" by data centers is actually withdrawn and returned, with only 20% consumed on-site for cooling. He calculates data centers use far less water than golf courses in Maricopa County. However, the debate continues, with proposals for data center water surcharges. Masley believes electricity demand poses a greater long-term risk, as utilities struggle to meet the power needs of the rapidly expanding industry. While data centers bring significant tax revenue, he cautions against policies that force consumers to bear the costs of infrastructure expansion.
