Future of Green Computing

Introduction OriginE-WasteAdvantages & Disadvantages of green computingPathways to green computingSri Lankan approachesFuture of 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.


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

E-Waste for short - or Waste Electrical and Electronic Equipment - is the term used to describe old, end-of-life or discarded appliances using electricity. It includes computers, consumer electronics, fridges etc which have been disposed of by their original users. "e-waste" is used as a generic term embracing all types of waste containing electrically powered components. e-Waste contains both valuable materials as well as hazardous materials which require special handling and recycling methods. This guide covers all categories of e-waste but emphasizes categories which contain problematic, scarce and valuable or otherwise interesting materials. 10

Disadvantages of Green ComputingHigh startup costNot readily availableStill in Experimental stageNot for everyoneHigh maintenance cost


1. Buy "Energy Star" labeled monitors, desktops,laptops, and printers2. 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 ManagementSri 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 VirtualizationEnergy SavingEco Friendly MaterialsRecyclingAnd etc.

VirtualizationVirtualization, 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


Future of VirtualizationVMwares Virtualization Progress

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

Natural Cooling SystemsSmart Plug

Solar Systems

Eco-Friendly mobile chargersEnergy 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


In future, almost all the computer devices and items will be able to be recycled

Recyclable PCBs

Recyclable Batteries

Take-back concept of the manufactures


Thats all about the future of Green ComputingIts not easy not being greenSo, Lets Go Green!
