• Introduction• Why Green• Problem• What can we do to go green• Benefits of green computing • Pros and cons• Summarize • Reference

Introduction

• “Going green with Computers ”

• “Green computing – great computing ”– Storage devices , networking and communication system efficiently and

effectively with no impact on the environment

Why Green• Overall energy cost need to be reduced

• Environment friendliness is important

• Computing –Centre power cost have more Than doubled in five years

• More utilization of power and money

Problem• It is estimated that out of $250 Billion per year spent on powering computers

worldwide only about 15%of that power is spent computing –the rest is wasted idling .

• Data centre are the main energy consumer . Energy consumed by data centre in the US and World Wide Double from 2000 to 2005.

• To Keep server at the right temperature , companies mainly rely on Air condition equipment .

• The SMEs will not be interested right now to change their IT infrastructure to green computing .

– Until the cost is recovered from the old infrastructure

What can we do to go green•Purchase flat screen monitors

•Unplug the electronics if not in use

•Consider a smaller monitor – a 14 inch uses 40% less energy than a 17 inch .•Enable the stand by / sleep mode and power management setting on your computer .

•Power off your monitor when you are not using it instead of using screen saver

What can we do to go green(cont..)

• Kill the vampires : Anything that uses a remote continues to consume power even when it’s turned off .- According the department of Energy “Vampire energy loss ” represents between 5 to 8 % of a energy bill .

• U.S agency launch Energy Star , labeling program buy energy star labeled instrument .

Pros and consPROS

1.Reduce power cost

2.Save Money

3.Be environmentally responsible

CONS

1.Initial setup cost

2.Consumer cared only about speed and price

3. Confusion to end users

Benefits of green computing • It save the resources of the country as a

whole

• In the long term these green equipment will be less costly without hidden cost .

• Minimized the power bill .

• Reducing global warming .

To summarize• Green computing is a novel and an innovative trend in the world of computing which has minimum or no impact on the environment.

• Green computing has introduced a range of equipments and technologies which help in limiting the impact on the environment.

•Building a healthy and safe place to live .
