GREEN COMPUTING

Green Computing can be described as the environmentally responsible usage of computer systems and related resources.

What is green computing???

Contd…….It is also known as the study

& practice of manufacturing, using & disposing of computers, servers & associated subsystems efficiently & effectively.

ORIGINIn 1992,the U.S Environmental Protection Agency launched “Energy Star”,a labeling programm designed to promote & recognize energy efficiency in monitors, climate control equipments and other technologies.

The term GREEN Computing was coined shortly after energy star programme.

Contd…….Concurrently, the Swedish organization TCO Development launched the TCO certification program to promote low magnetic and electrical emissions from CRT-based COMPUTER DISPLAYS.

The energy star program was revised in October 2006 to include stricter efficiency requirements for computer equipment, along with a tiered ranking system for approved products.

1.The main reason is the growing of public

environmental awareness.2.To reduce energy wastage.

3.It helps to save a lot of money.

The reasons for adopting

green computing

4.To reduce power consumption.5.To reduce impacts on environmental

& human health. The main aim is to reduce the amount of carbon emissions.

6.To avoid toxicity.Lead:-can cause damage to the central

& peripheral nervous system.Mercury:-can cause chronic brain

damages.Cadmium:-accumulate in the human

body specially the kidney.7.To reduce IT maintenance activities.8.To reduce the paper & other

consumables used.9.A corporate social responsibility.10.A step for need of tomorrows future.

E-Waste Definition

•  Any discarded electronic or electrical devices or their parts; also called electronic waste

• Examples: Computers, LCD / CRT screens, cooling appliances, mobile phones, etc., contain precious metals, flame retarded plastics, CFC foams and many other substances.

METHODS OF DISTROYING WASTE

Hazardous Technologies Recycling Technologies

Some Hazardous Components of E-Waste and Effects on Humans

•Renal Toxicity•Anemia•Colic•Insomnia•Seizures •Coma In Children

•Renal toxicity•Muscle tumors•Mental retardation•Cerebral palsy

•Cancer Of Skin•Lungs•Liver

•Respiratory Tract Irritation

• Suppression Of Immune System

• Damage To The Liver• Nervous• Reproductive Systems

Energy & Resources Saving

Environmentally Friendly

Cost Effective

Save Space

Reduce the Risk of Harmful Chemicals

Disadvantages of Green Computing• High startup cost• Not readily available• Still in Experimental stage• Not for everyone• High maintenance cost

1. Buy "Energy Star" labeled monitors, desktops, laptops, and printers 

2. Put laptops in "sleep" mode or “Hibernate” mode when not in use

Pathways to green computing

3. Turn OFF computers and other equipments when not in use4. E-cycle used computer equipments5. Buy the new “Smart Strip” power strip6.Set “Blackle” as your homepage

7. Use LCDs instead of CRTs as they are more power efficient- CRT uses 150 Watts 8 hours of usage, 5 days a week=562KWattsIf the computer is left on all the time, without proper power saver modes, this can leads to 1,600KWatts.

8. Buy Green products

Green Products

E-Waste Management• Sri Lankan Government has been initiated

e-waste collecting centers.• Ceylon Waste Management and their

Material Refining Process .

Sri Lankan Approach of Green Computing

Companies and Organizations

• Most of Sri Lankan Companies and Organizations already have took the first step to Green Computing.

• Following Standards for minimizing health effects and environmental effects.

Following Standards

Future of Green Computing “ The plan towards green IT should

include new electronic products and services with optimum efficiency and all possible options towards energy savings “

The future of Green Computing will be full of …• Virtualization• Energy Saving• Eco Friendly Materials• Recycling

And etc.

Virtualization

Virtualization, in simple terms, is moving physical servers to virtual ones.

What is Virtualization ?

Why is it important?

Few of the most important features of virtualization is that it…

Saves moneySaves energyReduce e-waste

Technologies used for Virtualization

Microsoft Virtual Server VMware

Future of Virtualization VMware’s Virtualization

ProgressDid you know ?50-60% of all servers are now virtualized

Natural Cooling Systems

Smart Plug

Solar SystemsEco-Friendly mobile chargers

Energy Saving

Eco Friendly Materials

Mercury-free backlighting and arsenic-free glass in displays

Not using Lead, Chromium Mercury and other toxic chemicals for manufacturing computer devices

Using recyclable or digital newspapers

RecyclingIn future, almost all the computer

devices and items will be able to be recycled Recyclable PCBs

Recyclable Batteries

Take-back concept of the manufactures

That’s all about the future of Green ComputingIt’s not easy not being greenSo, Let’s Go Green!
