Where demand signals run ahead of mapped supply — the United States
Every demand signal in the United States’s newsflow, measured as a share of the country’s own coverage (2025-07-01 to 2026-07-01, against the year before), then scored beside family-matched supply — the companies in each signal’s mapped energy categories — as within-page percentiles. The gap is signal percentile minus supply percentile — a prioritisation clue in percentile points, not a market size.

Related research & where the coverage is heading
The research below carries both a energy term and this page’s geography in its title — context for the boards above, not proof of any single number. The keywords are the fastest-growing terms in the United States coverage of this page's demand families, measured as a share of that coverage year-over-year so volume drift cancels.
