About Electronvolts
An electronvolt (eV) is the kinetic energy gained by one electron accelerated through 1 volt - exactly 1.602176634 × 10⁻¹⁹ J (fixed by the 2019 SI revision). It is the natural energy unit of atomic and particle physics: visible light photons carry 1.7-3.1 eV; hydrogen ionisation requires 13.6 eV; X-ray photons span 100 eV-100 keV; protons at the LHC reach 6.5 TeV. Rest masses use eV/c²: electron 0.511 MeV, proton 938.3 MeV, Higgs boson 125 GeV. Nuclear binding energy peaks at ~8 MeV/nucleon for iron-56. 1 eV = 1.602176634 × 10⁻¹⁹ J.
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.
