I think this is an interesting and well-balanced article. Some of the points it addresses are power and water usage, and tax incentives received by data center projects:
- Data centers in Chicago and surrounding suburbs use 1.2 gigawatts of power, projected to grow to 4.1 gigawatts; 1 gigawatt serves approximately 750,000 to 1 million homes
- 7.2% of power consumption in Illinois is from data centers, projected to increase to 15.6% by 2030 and further to 37.3% by 2040
- ComEd saw a 12% increase in monthly charges in June, following double digit increases starting in the summer of 2025
- Regarding water usage for evaporative cooling, a 1 gigawatt data center uses 5 to 10 million gallons per day, roughly equivalent to what 50,000 people use
- From 2020 to 2024, data centers received more than $983 million in tax incentives
- In 2025, Illinois committed to $66.6 million in additional tax credits over 20 years
- While many temporary jobs are added during the construction phase, 27 data centers have resulted in less than 600 permanent jobs
The Chicago area is a target for data center development for various reasons: nuclear energy means that the power requirements cost less and are more reliable than in other parts of the country; access to the Great Lakes means a reliable supply of water for evaporative cooling systems.
On the other hand, people are concerned about what the tax incentives mean for their own taxes, what the new/updated infrastructure and power and water usage will mean for their utility costs, and environmental and noise pollution, as well as privacy concerns as local governments increase AI surveillance that is supported by the data centers.
"But as they grow more and more prolific, the centers have come under fire for their large-scale consumption of electricity and water and growing brick-and-mortar presence. The tax breaks they’ve received, the noise they create and the relatively few people they employ once they’re running also add friction."
