About Ton of Oil Equivalent
A ton of oil equivalent (toe) is the IEA standard for comparing primary energy sources - defined as exactly 41.868 GJ (= 10⁷ International Table kcal). IEA World Energy Balances report in Mtoe: global primary energy supply is ~580 EJ ≈ 13,860 Mtoe/year. One tonne of coal equivalent (tce) = 29.307 GJ = 0.7 toe. Natural gas: ~0.9 toe per 1,000 m³; one barrel of crude oil ≈ 0.136 toe. Average EU citizen uses ~3.0-3.5 toe/year for all energy needs. 1 toe = 41.868 GJ = 11.63 MWh = 39.683 MBTU.
About Exajoules
An exajoule (EJ) is 10¹⁸ J - the scale of global energy consumption. World primary energy supply in 2022 was ~580-610 EJ: coal ~160 EJ; oil ~190 EJ; gas ~145 EJ; nuclear ~26 EJ; wind ~8 EJ; solar PV ~8 EJ. Global electricity generation of ~29,000 TWh = 104 EJ. Solar energy incident on Earth's atmosphere is ~5.5 × 10⁶ EJ/year - approximately 9,000× total human demand. Annual fossil fuel combustion releases ~490 EJ/year, producing ~36.8 Gt CO₂. 1 EJ = 10¹⁸ J = 277.78 TWh = 238.85 Mtoe.
