About Kilowatt Hour (kWh)
The global standard unit of electrical energy billing — equal to a kilowatt of power consumed (or delivered) for one hour, or 3,600,000 joules. Residential electricity bills, utility-scale grid planning, electric-vehicle battery capacities (e.g., Tesla Model 3 = 75 kWh), and home solar production are all quoted in kWh. Typical US household electricity consumption is about 900 kWh per month; EV efficiency is roughly 0.25 kWh per mile.
About Electronvolt (eV)
A unit of energy equal to the energy gained by an electron accelerating through a one-volt electric field (exactly 1.602176634 × 10⁻¹⁹ joules). The electronvolt is the working unit of atomic, molecular, and particle physics: chemical bonds are a few eV; X-rays carry keV (thousands of eV); nuclear reactions release MeV (millions); particle colliders operate at GeV-TeV (billions-trillions). Almost every modern particle-physics paper reports energies in eV.
