About Petajoules
A petajoule (PJ) is 10¹⁵ J - the national energy policy scale. IEA reports primary energy in PJ/year: Sweden ~600 PJ; Germany ~12,500 PJ; the United States ~93,000 PJ. World total primary energy supply is ~605,000 PJ = 605 EJ. The 1883 Krakatoa eruption released ~200 PJ ≈ 48 megatons TNT. A 1-megaton nuclear weapon releases 4.184 PJ. Global annual steel production embeds ~38,000-47,000 PJ of energy. 1 PJ = 10¹⁵ J = 277.78 GWh = 238.85 ktoe = 23.88 ktoe.
About Terajoules
A terajoule (TJ) is 10¹² J - the scale of nuclear yields in the kiloton range and large industrial accidents. One kiloton of TNT = 4.184 TJ; the Hiroshima bomb (15 kt) released ~62.8 TJ. The Halifax Explosion (1917) released ~3 TJ. A 500 MW coal plant consumes ~51.4 TJ/h of thermal input. Daily primary energy of Denmark is ~250-300 TJ; the UK ~3,800 TJ/day. A 1 GW nuclear reactor at 90% capacity factor generates ~77.7 TJ/day. 1 TJ = 10¹² J = 277,778 kWh = 277.78 MWh = 23.88 ktoe.
