About Attojoules
An attojoule (aJ) is 10⁻¹⁸ J - the scale of individual X-ray photons and superconducting qubit circuits. A 1 keV X-ray photon carries 160 aJ; a visible green photon (~550 nm) carries ~0.36 aJ. Josephson junction energies in superconducting qubits are set in tens to hundreds of aJ to achieve quantum coherence at millikelvin temperatures. XRISM's cryogenic TES X-ray spectrometer resolves individual photon energies at the hundreds-of-aJ level with ~7 eV FWHM resolution. 1 aJ = 10⁻¹⁸ J = 6.242 eV.
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.
