1. An information processing apparatus comprising: a first execution unit configured to execute a first job; a second execution unit configured to execute a second job irrespective of a reason for interruption of the first job; a calculation unit configured to calculate electric energy consumption in a period from a start of execution of the first job by said first execution unit to an end except electric energy consumption in a period from interruption of execution of the first job by said first execution unit to restarting, as electric energy consumption at the time of job execution, wherein the first execution unit performs a degeneration operation of a function in a case where the second executing unit starts and completes execution of the second job while the first execution unit interrupts execution of the first job due to the reason for interruption of the first job, and the calculation unit calculates electric energy consumption of the information processing apparatus in a period from interruption of execution of the first job by said first execution unit to restarting, except electric energy consumption in a period from a start of execution of the second job by said second execution unit to an end, as electric energy consumption during the interruption of the first job.
