About Kilowatt
Definition: The kilowatt hour (symbol: kWh) is the energy consumed by using one kilowatt of power for one hour.
History: Developed with electrical power systems for billing and measuring electrical energy consumption in practical units.
Current Use: Universal standard for electrical energy billing, power plant output, and electrical energy measurements.
Examples: Home daily use: 10-30 kWh, electric car: 0.3 kWh/mile, LED bulb: 0.01 kWh/hour, washing machine: 2 kWh/load
About Joule
Definition: The joule (symbol: J) is the SI unit of energy, equal to the energy expended when applying one newton of force through one meter of distance.
History: Named after English physicist James Prescott Joule in 1889. Established the mechanical equivalent of heat and energy conservation.
Current Use: Universal scientific unit for all forms of energy: mechanical, electrical, thermal, chemical, and nuclear energy worldwide.
Examples: Apple: 350,000 J, car battery: 4.3 MJ, lightning bolt: 1-5 billion J, human daily intake: 8-10 MJ
