Michigan researchers weigh in on data center debate
Researchers from the Citizens Research Council of Michigan presented findings on the impacts of data centers in the state. They suggest projects should be evaluated individually due to varying economic benefits and concerns about noise pollution, heat, and water quality. Existing regulations for water quality are in place, but other impacts are not accurately measured.
The Citizens Research Council of Michigan shared key findings on the impact of data centers within Michigan. Infrastructure research associate Eric Paul Dennis stated that data center projects should be considered on an individual basis, as not all projects are created equal and many are subject to undeserved backlash.
Dennis's research indicates that while few data center projects are large-scale, those that are, like the example of a "barn data center," offer limited economic growth. Such projects might create a few jobs through contracted services or utility support, but generally do not serve as a reliable economic development approach.
While the Michigan Department of Environment, Great Lakes, and Energy (DEQ) has regulations to prevent data centers from compromising state water quality, Dennis highlighted noise pollution as a significant, yet inaccurately measured, risk. He explained that data centers produce unique low-frequency noise that is not adequately captured by typical A-weighted decibel measurements. He also emphasized the need for further research into the heat generated by large data centers, particularly those using evaporative cooling, which can release water vapor (a greenhouse gas) and potentially increase local temperatures. Dennis suggested that strategically placed trees and green spaces could help offset these heat increases.
