What impacts could new data centers have in Wisconsin? Environmental expert weighs in

Data centers are rapidly expanding in Wisconsin, with large "hyperscale" facilities being proposed that can use as much energy as an entire city. These data centers raise significant environmental concerns, including massive water and energy demands, air pollution from backup diesel generators, and the use of potentially harmful chemicals in cooling systems. However, local communities may be attracted by the economic benefits, such as construction jobs and tax revenue. Experts argue that data centers need to be powered by renewable energy and include measures to reduce environmental impact, rather than relying heavily on fossil fuels. There are also concerns about what happens when these specialized facilities become obsolete. Overall, the rapid growth of data centers in Wisconsin presents complex tradeoffs that communities and policymakers must navigate.
