Energy Security Is Shifting From Just-in-Time to Just-in-Case
Fatih Birol of the International Energy Agency argues that energy security is shifting from a just-in-time model built around cheap supply to a more expensive “just in case” system of reserves, alternate routes, grids and trusted partners. Alongside Meghan O’Sullivan of Harvard and former U.S. deputy energy secretary Daniel Poneman, he contends that disruptions from Hormuz to mineral refining expose a wider set of dependencies: electricity and nuclear fuel, transmission capacity, processing and long-term finance. The central constraint, they argue, is not simply resource availability but the ability to build and sustain resilient supply systems.
