About Kilowatt-Hours

A kilowatt-hour (kWh) is the energy consumed by 1 kW for one hour - exactly 3,600,000 J = 3.6 MJ. All domestic electricity meters bill in kWh. Appliance benchmarks: fridge 180-250 kWh/year; washing machine 0.5-2.0 kWh/cycle; air conditioner 1-3 kWh/h. EVs consume 13-25 kWh/100 km; the Lucid Air achieves ~15.9 kWh/100 km (WLTP). Producing 1 tonne of primary aluminium requires ~13,000-15,000 kWh. Global electricity generation is ~29,165 TWh ≈ 2.9 × 10¹³ kWh/year. 1 kWh = 3.6 MJ = 3,412.1 BTU = 859.85 kcal.

About Megatons of TNT

A megaton of TNT (Mt(TNT)) = 10⁶ tons of TNT = exactly 4.184 PJ. The Soviet Tsar Bomba (1961) yielded ~50 Mt - the largest human-made explosion ever, with a fireball 8 km in diameter. Castle Bravo (1954) yielded ~15 Mt, 2.5× its 6 Mt design yield. Modern thermonuclear warheads typically range from 0.1-1.2 Mt. The 2011 Tōhoku earthquake released ~500 Mt in seismic energy. The Krakatoa 1883 eruption released ~200 Mt; Tambora 1815 ~33,000 Mt. 1 Mt(TNT) = 4.184 PJ = 1,162,800 MWh.
