How this figure is calculated
Annual change in primary energy use divided by Land area (sq. km), matched on country and year. Neither publisher issues this ratio as a series; it is computed here from both.
Annual change in primary energy use ÷ Land area (sq. km)
Computed from
- Annual change in primary energy use Energy Institute – Statistical Review of World Energy (2026); U.S. Energy Information Administration (2026) – with major processing by Our World in Data
- Land area FAOSTAT, Food and Agriculture Organization of the United Nations (FAO)
Statizoid computes this series; the underlying measurements belong to the publishers named above. The arithmetic is applied to every country and year where both inputs report, and nothing is estimated unless the page says so.
