GREEN COMPUTING

1Overview

Green computing the term refers to efficient use of resources in computing

Its also known as green IT.

Key issues are energy efficiency in computing and promoting environment friendly computer technologies2Concept

Concept of green computing began with Energy Star program way back in 1992.One of the fist result was the Sleep Mode function in monitors.As the concept developed it let to developments of Thin client solutions Virtualization PracticesEnergy star served as a kind of voluntary label awarded to computing products that succeeded in minimizing use of energy while maximizing efficiency.

3Approaches to Green ComputingVirtualization Computer virtualization is the process of running two or more logical computer systems on one set of physical hardware .

4Power Management ACPI allow an OS to control the power saving aspects of its underlying hardware. Improve battery life for portable & embedded systems Reduce cooling requirements. Reduce noise Materials Recycling Parts from outdated systems should be salvaged and recycled

5Displays LED is the latest trend uses array of light emitting diodes Consumes less energy when compared to its predecessors CRT LCD LED

6 Pathways to Green Computing

Green Design : Designing of Energy efficient data centres and workstations Green Manufacturing : Manufacturing electronic components, computer and other associated subsystems with minimal impact on the environment

8Green ITSo far, we havent cared about ecological impact when buying computers, we ve cared only about speed and priceNew green materials are developed every year and many toxic ones are already being replaced by them .Plan towards green IT should include new electronic products and. services with optimum efficiency and all possible options towards energy savings.
