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 Ergs
An erg is the CGS unit of energy - the work done by one dyne through one centimetre - exactly 10⁻⁷ J. Despite SI adoption, the erg persists in astrophysics: the Sun's luminosity is 3.828 × 10³³ erg/s; gamma-ray burst isotropic energies are quoted in units of 10⁵¹ erg ('one foe'). Surface tension of water is 72.8 dyn/cm; the work to create 1 cm² of new water-air interface is 72.8 erg. Earthquake seismic moment M₀ is in dyn·cm = erg; the 2004 Boxing Day earthquake had M₀ ≈ 10²³ J = 10³⁰ erg. 1 erg = 10⁻⁷ J = 624.15 eV.
