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.

Excerpt from the Book
4. Green Strategies of Grid: SymbioticSphere and Energy-Aware Reservation Infrastructure (EARI)
SymbioticSphere is a biologically-inspired architecture design for data centers, which makes them capable to adapt dynamic environmental changes, survive partial system failures and reach energy efficiency. The concept of this system is based on the life cycle of bee colonies, where each server and platform is analogous to an individual bee, autonomously acting, interacting and adapting to changes of environment whereas server farms are designed to follow biological principles, such as natural selection, decentralization and symbiosis.
EARI on the other hand is based on the recognition that server farms have their capacity designed to satisfy the maximum task load of busy periods when the demand from the end-user side is the highest. According to this there are huge amounts of waste energy in idle periods mostly emerging from booting, shutting down, idle state consumption and when they are connected to the energy source but not actively operating. The designers intended to develop an optimal scheduling algorithm that switches off the unused nodes, predict which nodes are to be used in the near future, and switches them on, and aggregate tasks to prevent too frequent on-off switches.
Simulations show that these server grids are both capable of saving up to 50% of the energy on their platform.
Further along this chapter we will examine the design principles, the architecture and the working methods of these platforms with the aim of pointing out similarities and differences in their activities, so that we can better understand how these and analog platforms function.
Summary of Chapters
1. Introduction: This chapter highlights the alarming impact of global warming and the corresponding need to reduce greenhouse gas emissions within the ICT sector by 2020.
2. Key actions and guidelines for the ICT sector: The chapter outlines five key actions, including standardization and real-time monitoring, to create a more efficient and accountable low-carbon economy.
3. The challenge of the data center: This section discusses the rapid growth of server farms and the massive energy demand required for storage, networking, and cooling systems.
4. Green Strategies of Grid: SymbioticSphere and Energy-Aware Reservation Infrastructure (EARI): This chapter presents and compares two distinct architectural models—a decentralized, biologically-inspired system and a centralized, reservation-based scheduling infrastructure.
5. Conclusions: The final chapter synthesizes the findings, noting that while both systems effectively reduce energy waste, they differ significantly in their reliance on user decision-making and centralization.
