Calculation
E = P · t
Energy is power over time; a short high load can use the same energy as a long low load.
E = P·t

Select a target and calculate.
Understand the inputs
- Electrical energy E — Consumed work; kWh is the unit used by electricity meters.
- Power P — Instantaneous or average real power.
- Operating time t — Time for which the power is applied.
Example
1 kW for 2 h consumes 2 kWh.
Assumptions and limits
Constant average power; standby and load changes are not modeled separately.
