The energy label a need to networks and devices

The energy consumption of Information and Communication Technologies (ICTs) is today relevant also compared with the other industries. The evolution of ICT will determine enormous improvements in our daily lives, but will also increase energy need. So energy consumption becomes one of the key aspects in the evolution. Today every vendor manifests a trend to improve energy saving, but the lack of agreed indexes, terms, definitions and procedures makes it difficult for the customer to realize a relevant comparison. This paper presents a holistic approach in order to identify energy key indexes in all the Life-Cycle Assessment (LCA) of devices and networks. This study starts with the analysis of what was already implemented in other sectors and it proposes a devices energy label and a network energetic classification. A case study on the proposed method application is described. The results of the study demonstrates the need to adopt regulatory energetic indexes in order to ensure competition and energy saving.
