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 British Thermal Units
A British Thermal Unit (BTU) - the heat to raise 1 lb of water by 1°F - equals exactly 1,055.05585262 J. It dominates US HVAC: room air conditioners are rated in BTU/h (5,000-24,000 BTU/h = 1.5-7.0 kW); one ton of refrigeration is exactly 12,000 BTU/h. Natural gas is billed in therms (100,000 BTU) in the US. Higher heating values: natural gas ~1,020-1,050 BTU/ft³; No. 2 fuel oil ~138,700 BTU/US gal; propane ~91,500 BTU/US gal. 1 BTU = 1,055.06 J = 252.164 cal = 0.29307 Wh.
