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 Microjoules
A microjoule (µJ) is 10⁻⁶ J - the scale of precision laser ablation, ESD damage events, and individual LIDAR pulses. LASIK eye surgery delivers 0.5-2 µJ per pulse at 193 nm, ablating ~0.25 µm of corneal tissue per pulse. ESD events that destroy IC gates correspond to 1-1,000 µJ; the Human Body Model test discharges ~500 µJ at 2 kV. Q-switched microchip laser pulses for rangefinding are 1-100 µJ. The kinetic energy of a 1 mg grain of sand falling 10 cm is mgh ≈ 0.98 µJ. 1 µJ = 10⁻⁶ J.
