Energy has long been used as a weapon. The United Kingdom blocked oil exports to Germany during World War I. Hitler's fall was due in part to losing access to oilfields in the Caucasus. And the most recent example: the 1973 Arab oil embargo, which shocked the global economy.

During the following fifty years, the energy weapon largely receded from the geopolitical stage, and in many countries energy security started to feel like a given. But developments including Russia's weaponization of natural gas against Europe, China's restrictions on critical minerals, and growing trade tensions around the world have brought energy back to the center of great-power competition.

So is this a new age of energy weaponization? What would that mean for global energy security? What new vulnerabilities are emerging as the clean energy transition accelerates and electricity demand surges? And how can countries protect themselves in this new age of fragmentation and rivalry?

This week, Bill Loveless speaks with Jason Bordoff and Meghan O'Sullivan about "The Return of the Energy Weapon," a Foreign Affairs essay published today, in which they explore how, after a fifty-year period of relative stability, the use of energy as a coercive tool of statecraft is making a comeback.

Jason is the founding director of the Center on Global Energy Policy at Columbia University's School of International and Public Affairs, where he is a professor of professional practice. He is also on the faculty of the Columbia Climate School, where he is cofounding dean emeritus. He previously served as special assistant to President Barack Obama and senior director for energy and climate change on the staff of the National Security Council.

Meghan is the Jeane Kirkpatrick Professor of the Practice of International Affairs, director of the Geopolitics of Energy Projects, and director of the Belfer Center for Science and International Affairs at Harvard University's Kennedy School. She has served in multiple senior policymaking roles and has advised national security officials in both Republican and Democratic administrations.
