Energy Efficiency of Server Grids

According to the estimations the level of carbon emission in the sector of information and communication technologies triples by 2020 . This raised concern regarding the energy efficiency of the ICT devices and systems. Further we will discuss the guidelines and directives along which we can differentiate between technologies and their efficiency-level. These guidelines not only enable the customer of these services to attain a simple and easily manageable view on his consumption as technology user, but it also provides an evaluation system for local governmental and international regulators and projects. Then we examine the problem of energy efficiency in a specific field of the ICT, the server grids, as the demand for the services of this area is one of the fastest growing sections of the ICT sector. Than we rule out two possible ways of solving energy efficiency on the grids, and compare them. Finally in the conclusion we point out the main factors that make these solutions successful, and to which extent they match to our guidelines.
