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 Femtojoules

A femtojoule (fJ) is 10⁻¹⁵ J - the scale of gamma-ray photons, molecular motor work, and state-of-the-art digital logic. The electron rest-mass energy is 81.87 fJ; a 100 keV X-ray photon carries 16.02 fJ. A single myosin II motor protein power stroke dissipates ~5-40 fJ. ATP hydrolysis under cellular conditions yields ~80-100 fJ of free energy. Advanced 3 nm CMOS gates switch at ~0.1-1 fJ per operation. Ultrafast fiber laser oscillators produce pulses of 0.1-10 fJ before amplification. 1 fJ = 10⁻¹⁵ J = 6.242 keV.
