The data center industry is being pulled in two directions at once: demand that shows no sign of slowing, and physical constraints that are getting harder to work around. How operators, utilities, and policymakers navigate that tension will shape the cost, speed, and environmental footprint of every digital service built on top of this infrastructure.
