Energy Nexus released maps are reviewed map views of energy, published once their data rights are cleared, each with its coordinate reference, date, sources and uncertainty. Layers draw on sources such as IEA World Energy Balances. A map shows released, rights-cleared evidence, not a live feed or an official warning.

Where demand concentrates in cities and the rail, road and port corridors that move fuel and equipment, shown for Eastern Europe as an example geography for this subject.

Each term as this page uses it. Where a standard-setting body defines the term, the wording follows that body.
| Term | Definition |
|---|---|
| Coordinate reference system | The definition that ties coordinates to locations on Earth, catalogued with EPSG codes. |
| Modifiable areal unit problem | The change in statistical results that comes from how areas are drawn and aggregated. |
| Zonal statistics | Statistics of raster values summarised within boundaries such as districts. |
| Public-safe release | A recorded decision on the detail at which a layer may be published without exposing sensitive sites or people. |
