What is Energy?
Energy is the capacity of a physical system to do work or produce heat. The SI unit is the joule (J), defined as the work done when a force of one newton is applied over one meter (1 J = 1 N·m = 1 kg·m²/s²). Other important units include the kilowatt-hour (kWh)—used on electricity bills (1 kWh = 3.6 MJ)—the calorie (cal)—used in nutrition (1 food Calorie = 1 kcal = 4,184 J)—and the electronvolt (eV), used in atomic and particle physics (1 eV = 1.602 × 10⁻¹⁹ J).

What is Watt-hour?
A watt-hour (Wh) is a unit of electrical energy equal to one watt of power consumed for one hour. The watt-hour is the standard energy unit in electrical engineering, utility billing, and appliance labeling. Electricity meters on homes measure consumption in watt-hours (or kilowatt-hours for larger quantities). Household appliances specify energy consumption in watt-hours per day or per year. The watt-hour integrates naturally with power measurements (watts) and time duration (hours), making it intuitive for engineers and accessible for consumers understanding their electricity bills.
