Aerial of COL4 AI Data Center

COLUMBUS, OHIO - JULY 24: The COL4 AI-ready data center is located on a seven-acre campus at the convergence point of long-haul fiber and regional carrier fiber networks on July 24, 2025 in Columbus, Ohio. COL4 spans 256,000 square feet with 50 MW of power across three data halls. There are concerns that new AI data centers are hiking up electricity rates due to their massive energy consumption for training and operating AI models, coupled with the need for advanced cooling systems. The Ohio Tax Credit Authority has offered sales tax exemptions and incentives for new AI data centers in Ohio for development costs. (Photo by Eli Hiller/For The Washington Post via Getty Images)
