Underwater Green Computing

Shanghai’s underwater green computing project demonstrates how digital infrastructure is evolving to meet rising AI and cloud-computing energy demands with lower environmental impact. The underwater data center combines offshore wind power with seawater cooling, allowing the facility to operate with a Power Usage Effectiveness (PUE) below 1.15. By locating the center near offshore renewable energy sources, the system reduces transmission losses while cutting freshwater usage and cooling costs associated with traditional onshore facilities.

The project also highlights broader business implications for the future of global computing infrastructure. As AI workloads continue to increase electricity consumption, companies and governments are seeking more energy-efficient ways to expand data processing capacity. Offshore renewable-powered data centers could help reduce operational expenses, improve sustainability performance, and support stricter carbon reduction goals. Shanghai’s deployment positions underwater computing as a scalable model for future low-carbon digital infrastructure and green AI expansion.
