This paper summarizes recent explorations of the use of lifetime exergy consumption as a thermodynamically based metric for sustainability of information technologies. Other proposed thermodynamic metrics are described and compared with life cycle exergy consumption. The pros and cons of different metrics are discussed, and the advantages of life cycle exergy as a metric for information technologies...
The energy efficiency of information processing is typically evaluated purely by how much power is consumed during operation. The reality is that the sustainability of energy use for information processing depends on the lifetime exergy (available energy) consumption of the equipment used. This paper explores the lifetime exergy consumption of an enterprise server used in a data center. By combining...
