There is permanent growth of requirements for power efficient operation of the majority of portable computing devices. In this paper the author considers power efficient software design and proposes metrics for energy consumption analysis in software systems. Sources of power consumption in digital circuits are considered. It was proved that power consumption depends on executing software. The author gives a description of energy measures which form a basis for definition of software energy metrics. The defined metrics can be used for calculating the level of energy consumption of any software system.
