Every form of energy on Earth traces back to the sun, and every piece here is one measured part of that picture. Five evidence questions meet six scales, from the whole Earth on the outer ring to one site at the centre. The puzzle fills as data products land, showing what we know and where the gaps remain.
A filled piece holds at least one current data product. A hatched piece holds only products that are recovering. A dashed outline is a gap. Every piece is listed below with its products.

Each product in the register sits in one piece. Its sector is the evidence question the site already files it under. Its ring is the widest scale its own coverage statement describes, which is an editorial judgement and can move. Evidence columns shows the same questions as columns and scales as rows.
Read the concentric puzzle from the outside in: Earth, nations, grids, networks, neighbourhoods and individual sites. The five sectors are evidence questions, not shares of a total. Each question carries its earliest recorded year; the scale key shows its fastest update cadence. Both measures come from the products themselves.
A gap is a piece no current product answers. Its note says what kind of data would fill it, which describes the hole rather than promising to fill it. The full product list, with source health, is in data operations.
