The electrical cost of managing information systems has always been a concern for those investing in technology. However, in recent years the focus has increased, both because of increased costs of electricity and decreased costs of other components of the equation.

To understand the efficiency of a computing solution, one needs a measure of throughput per watt (or watts per unit of work) that employs a workload that is relevant to the target load on the system and that operates at a capacity that reflects the target throughput of the final application. The goal of this paper is to introduce the reader to some of the measures that are available and provide an explanation of the relative merits of each.
