A country’s energy footprint is shaped by its climate, industrial base, transportation, and economic structure. This gallery ranks the top 30 countries by total energy supply per person in 2025, measured in gigajoules (GJ), where 1 GJ equals roughly 278 kilowatt-hours, using data from the Energy Institute’s Statistical Review of World Energy 2026.
This metric divides an entire nation's energy use, including heavy manufacturing, power plants, and commercial transport, by its population. It reflects how energy-intensive the overall economy is, rather than how much power individual citizens consume at home.
