What they’re saying

“Whatever we do here, we have to put people first. We have to put communities first. Data's important, business is important, revenues are important, but people must come first.”

— Rep. Ann Williams, Chair, Illinois House Executive Committee

“When Meta first came to our community, they specifically said they want to make a significant impact in everything they do where they have a physical presence, and that's just what they did.”

— Mayor Cohen Barnes, Mayor of DeKalb, Illinois

“Residents living near data centers have described a constant low frequency hum day and night. It's not loud in a traditional sense, but persistent. People have described trouble sleeping, increased stress, loss of quiet in their own homes.”

— Mayor John Laesch, Mayor of Aurora, Illinois

“Rather than fixing the noise in Aurora, they're expanding with a bigger project in Sangamon County. So this aspect of being a good neighbor, we're torn with that because they're not really being a good neighbor right now in Aurora.”

— Marc Ayers, Former Sangamon County Board Member

“We believe Illinois can maintain its lead in this race with the right balance of incentives, labor standards, local protections and infrastructure planning. We can attract investment while ensuring communities benefit workers are treated fairly, and our energy and water resources are responsibly managed.”

— Joe Duffy, Climate Jobs Illinois

What’s next

The Illinois Senate is scheduled to hold two additional data center-related hearings later this week, as lawmakers continue to examine the impacts of the growing industry and consider potential new regulations.

The takeaway

Illinois lawmakers are grappling with the complex tradeoffs of data centers, seeking to balance the economic benefits with the environmental and community concerns. As the state considers new rules, finding the right equilibrium will be crucial to supporting innovation while protecting local residents and resources.
