A new Marquette University Law School poll has found a significant shift in public opinion in Wisconsin against the development of data centers. The poll shows that 70% of registered voters now feel the costs of data centers outweigh the benefits, up from 55% in October. The opposition is particularly strong among Democrats, independents, and union members.

Why it matters

The growing public opposition to data centers could impact future development and investment in this industry in Wisconsin. As more people voice concerns over issues like water usage, electricity costs, and the replacement of rural land, policymakers may face increased pressure to reevaluate incentives and regulations around data center projects.
