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 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.
