The energy transition is a materials story. 7 chains rendered depth-first.
Chokepoint Index
How it’s calculated
Chokepoint Index = mean of the top-5 layer scores for this sector.
Each layer score = concentrationScore × downstreamDemandMultiplier, clamped to 0–100.
A score of 100 means a single dominant supplier (or a 2-supplier oligopoly) with maximum downstream demand.
