Energy Security

How nations protect themselves from energy supply disruptions — strategic reserves, diversification, and the security dilemma.

Securing the Energy Supply

Energy security — the reliable availability of energy at affordable prices — is a core national security concern. Disruptions to energy supply can cripple economies, trigger social unrest, and constrain military operations.

Countries pursue energy security through several strategies. Strategic petroleum reserves provide a buffer against short-term disruptions: the US Strategic Petroleum Reserve (SPR) holds roughly 400 million barrels. Diversification of supply sources reduces dependence on any single provider — a lesson Europe learned painfully in 2022. Domestic production, including the US shale revolution, can transform a country's strategic position.

Energy efficiency reduces overall demand and vulnerability. Japan, after the Fukushima disaster eliminated its nuclear power capacity, became a world leader in energy efficiency. Nuclear power provides baseload electricity without fossil fuel imports, though it carries its own risks and controversies.

The energy transition to renewables is increasingly framed as an energy security strategy — solar and wind are domestic resources that cannot be embargoed. However, the transition creates new dependencies on critical minerals, many of which are concentrated in a handful of countries.
