Energy over time equation

http://www.mrelativity.net/TimeEnergy/TimeEnergy.htm WebEnergy = Power × Time A low power device operating for a long time can use more energy than a high power device operating for a short time. For example: A 60W lamp switched on for 8 hours uses 60W × 8 × 3600s = 1728kJ. A 3kW kettle switched on for 5 minutes uses 3000W × 5 × 60s = 900kJ.
