CyrusOne’s Jim Roche details how AI-driven workloads, high-density racks, and liquid cooling are transforming the data center–utility relationship. Only a decade ago, few in the power sector could have predicted that the digital economy’s engine—the data center—would become a central concern for utility planners, grid operators, and energy policymakers. For much of its history, data […]

I’m lucky to learn firsthand about some of the world’s most cutting-edge technologies. I’ve seen artificial intelligence ace an AP biology test, long before AI became an everyday tool. I’ve seen genetically modified mosquitoes that stop malaria in its tracks. I’ve seen geothermal wells that go 15,000 feet below the surface of the earth.   But […]
