The average electric kettle uses between 1.5 to 3 kilowatts per hour (kWh). Energy usage for the kettle depends on multiple factors, like the energy rating of the kettle itself and how the energy usage is measured.
Many electronic devices and appliances include a label or tag that identifies how much energy the item uses. The energy rating is usually measured in power used per hour, either by watts or kilowatts.
The average modern electric kettle uses between 1.5 and 2 kilowatts per hour (kWh). However, the use of a data logger inside a heating kettle reveals that energy measurements related to the process of heating the water inside the kettle differ. It may require up to 3 kWh to heat the water from cold to boiling.
It is also important to remember that older-model kettles may use more power than a modern kettle.
