About Gigawatt-Hours

A gigawatt-hour (GWh) is the energy from 1 GW for one hour - exactly 3.6 TJ. National electricity generation is reported in annual GWh: Ireland ~32,000 GWh/year; France ~496,000 GWh/year. The Hornsea One offshore wind farm (1.12 GW) generates ~4,000 GWh/year. The Bath County Pumped Storage (3 GW, USA) stores ~24 GWh. World total battery storage capacity reached ~1,600 GWh by end-2022. Energy of 1 megaton TNT ≈ 1.162 GWh. 1 GWh = 3.6 TJ = 1,000 MWh = 3.412 × 10⁹ BTU.

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.
