This week saw major developments in AI-driven city planning worldwide. In the U.S., the Department of Energy picked 16 sites for new AI-ready data centers that will use nuclear and renewable energy to power smart city tech. These centers will help cities manage traffic, healthcare, and energy needs more efficiently.

China’s Yizhuang city is testing AI medical tools like smart patient triage and doctor appointments. They’re also using AI to control traffic lights and reduce road jams by connecting cars, roads, and cloud systems. In Nigeria, Lagos started using AI to plan better bus routes and schedules to fix traffic problems in its crowded streets.

Tech companies are switching focus to support AI cities. IREN stopped Bitcoin mining to build AI data centers. Japan’s NTT began construction on a Tokyo-area data center for AI and cloud services. Italy’s CyrusOne built a solar-powered data center in Milan to handle growing AI demands while cutting pollution.

These projects show how cities are racing to use smart AI tools for cleaner energy, smoother traffic, and better healthcare. Challenges remain in balancing energy needs with environmental goals as AI infrastructure grows.
