Data centers may raise neighborhood temps, ASU research suggests

Research conducted by Dr. David Sailor at Arizona State University indicates that data centers could be contributing to increased temperatures in surrounding residential areas. Preliminary findings, gathered by monitoring air temperatures around data center sites, suggest an elevation of up to four degrees Fahrenheit hundreds of yards downwind from these facilities. This heat rejection is a byproduct of the extensive cooling systems required by data centers, especially those powering AI applications, which consume significant amounts of electricity. Dr. Sailor explained that the waste heat generated by a data center, even a mid-sized 30-megawatt facility, often exceeds its electricity consumption, equivalent to the power usage of 20,000 to 30,000 homes. Depending on atmospheric conditions, this heat either dissipates vertically or is carried by wind into adjacent neighborhoods. While the current data is preliminary, Sailor aims to conduct a larger study to precisely quantify this thermal impact and explore methods to mitigate it. This research adds a new dimension to the ongoing debate surrounding data centers, which have already faced scrutiny for their considerable demands on local water and electricity resources. The article also briefly references a recent decision by the Chandler City Council to unanimously reject a proposed $2 billion AI data center, highlighting existing community concerns.
