The kilowatt.hour (kWh)
More details
No matter whether we are talking about electrical work or mechanical work, in engineering all measurements of actual work done are measured as the power used over a period of time.
The standard unit used to measure power in electrical engineering is the kilowatt and time periods are measured in hours, so the work done is measured in kilowatt.hours (kWh).
Exactly the same unit is used to measure amounts of energy used.
The energy transfer from a source of power to produce an end-result of work done can never be 100% efficient so the energy used (measured in kWh) will always be more than the actual work done (also measured in kWh).
A further fact
In the United Kingdom, electricity companies charge their customers by the unit. The term 'unit' is short for the obsolete expression 'Board of Trade Unit' and is a measurement of electrical energy, equivalent to a kilowatt hour. So, 1 unit = 1 kW.h.
