About Joule (J)
The SI derived unit of energy, one joule equals the work done by a force of one newton moving an object one meter. Named after James Prescott Joule, who demonstrated the mechanical equivalent of heat, the joule is used in physics, chemistry, and engineering for all forms of energy, work, and heat.
About Kilowatt-hour (kWh)
The standard billing unit for household electricity worldwide, one kilowatt-hour equals 3.6 megajoules. Running a 100-watt light bulb for 10 hours consumes one kWh. Average US household electricity consumption is about 30 kWh per day, and electric vehicle batteries hold 40-100 kWh.
