Energy Security Four Dimensions

In early 2022, Europe had plenty of natural gas in the global market. What it did not have was a way to get that gas to German factories and French homes after Russia cut pipeline deliveries. Europe's energy crisis was not about availability. It was about accessibility. Confusing the two dimensions leads to the wrong policy response.

Energy security has four dimensions, known as the Four A's. Availability: Do sufficient energy resources physically exist? (Yes, global gas reserves are enormous.) Accessibility: Can those resources reach the consumer through existing infrastructure? (Europe's pipeline dependence on Russia meant alternatives required LNG terminals that did not yet exist.) Affordability: Can consumers and industries pay the price? (European gas prices rose 10x, devastating energy-intensive industries.) Acceptability: Does the energy source meet environmental and social standards? (Coal was brought back despite climate commitments, revealing the tension between acceptability and the other three A's.)

Diagnose the 2022 crisis. Availability was never the problem. Global LNG capacity existed. Accessibility failed first (pipeline dependence), which triggered affordability failure (price spikes from scrambling for alternatives).

Can a country be energy-secure on all four dimensions simultaneously?

The tradeoff structure. Maximizing affordability (cheap coal) conflicts with acceptability (climate targets). Maximizing accessibility (diverse import routes) requires expensive infrastructure that hurts affordability. Energy security policy is about managing these tensions, not eliminating them.

The Four A's framework prevents single-dimension thinking that misdiagnoses crises and prescribes incomplete solutions.
