GREEN COMPUTING

GREEN COMPUTING                       

INTRODUCTION:

·      We can’t live without PC’s, so let’s learn how to live with them in a way that makes them friendlier to the environment

·      Green computing, also called green technology Green computing is the environmentally responsible use of computers and related resources

·      As businesses are growing computing is becoming increasingly evident, despite the scarcity of resources and desperate need to reduce adverse impact on the environment

·      Green computing or green IT, refers to environmentally sustainable computing or IT. Dr. San Murugesan a Senior Consultant defines the field of green computing as "the study and practice of designing, manufacturing, using, and disposing of computers, servers, and associated subsystems—such as monitors, printers, storage devices, and networking and communications

·      Green IT also brings with it direct cost benefits for the organization, making it an easier sell to the more sceptical boards of directors.  With a Green Computing or IT Strategy we can reduce equipment, power, air-conditioning, and support costs.  This applies throughout the enterprise  not just in data-centers or our server rooms but desktop computers as well.

HISTORY:

In 1992,the U.S. Environmental Protection Agency launched “ENERGY STAR”, a labelling program designed to promote and recognize energy efficiency in monitors, climate control equipment etc.

The term GREEN COMPUTING was coined

shortly after energy star began.

Green computing ……… what and why green computing  is needed ?

v Green  computing is        the environmentally responsible & eco-friendly use of computers & their resources.

v IT Executives are at last coming under increasing pressure to deliver a Green IT or Green Computing Strategy

v Having a Green IT Strategy can directly affect the view of the organizations customers.

v Customers will clearly continue to evaluate suppliers based on product/service offerings and their costs, however, if all else is equal, then choosing a supplier with a low carbon policy can be a key differentiator.

                                            

DEFINITION:

Ø It is the study of designing, manufacturing, using &disposing of computing devices in such a way that reduces environmental impact

Roads to green computing ……

Green use: Minimizing the electricity consumption.

Green disposal: Re-making an existing computer or recycling, unwanted electronic equipment’s.

Green design: Designing energy – efficient computers, and other digital devices.

Green manufacturing: Minimizing waste during the manufacturing of computers and other subsystems to reduce the environmental impact of these activities.

Approaches to Green Computing

Virtualization:

     >Computer virtualization is the process of running two or more logical computer systems on one set of physical hardware.

                  >With virtualization, a system                  administrator could combine several physical systems into virtual machines on one single, powerful system, thereby unplugging the original hardware and reducing power and cooling consumption.

Power Management: Power management for computer systems are desired for many reasons, particularly:

Prolong battery life for portable and

 embedded systems.

 Reduce cooling requirements.

 Reduce noise.

 Reduce operating costs for energy and cooling.

Power Supply: Power supplies in most computers (PSUs for short) aren't designed for energy efficiency. In fact, most computers drain more power than they need during normal operation, leading to higher electrical bills and a more dire environmental impact.

The 80 Plus program is a voluntary certification system for power-supply manufacturers.  If a PSU meets the certification, it will use only the power it needs at a given Load i.e. it won't use more power than it needs. Various initiatives are underway to improve the efficiency of computer power supplies.

Storage:

There are three routes available, all of which vary in cost, performance, and Capacity.

The most conventional route is the 3.5" desktop hard drive. For laying focus on reduced power consumption reduced RAM low power idle mode with fixed rotation speed have come in scene. Its advantage is highest possible capacity plus the best performance.

The second option is to use a 2.5" laptop hard drive. These consume less power than larger disks as a result of their smaller platters, smaller motors, and firmware.

Materials Recycling:

Computer recycling refers to recycling or reuse of a computer or electronic waste Additionally, parts from outdated systems may be salvaged and recycled through certain retail outlets and municipal or private recycling centers.

Recycling computing equipment can keep harmful materials such as lead, mercury, and hexavalent chromium out of landfills. Computing supplies, such as printer cartridges, paper, and batteries may be recycled as well.

Obsolete computers are a valuable source for secondary raw materials, if treated properly, however if not treated properly they are a major source of toxins and carcinogens.

 TELECOMPUTING:

Teleconferencing and telepresence technologies are often implemented in green computing initiatives. The advantages are many; increased worker satisfaction, reduction of greenhouse gas emissions related to travel, and increased profit margins as a result of lower overhead costs for office space, heat, lighting, etc…

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. That is enterprise wise companies are laying emphasis on moving towards Eco Friendly Components in Computers, the use of eco-friendly sustainable components will become the norm rather than the exception in future.

To this approach for an instance - A Canadian Company, Userful Inc. (www.userful.com) have come up with a solution that turns 1 computer into 10 - Discover Station.  Quickly becoming the standard for green computing worldwide, Discover Station leverages the unused computing power of modern PC’s to create an environmentally efficient alternative to traditional desktop computing. Multiple users can work on a single computer by simplyattaching up to 10 monitors, mice and keyboards.  This makes it possible to reduce CO2 emissions by up to 15 tons per year per system and reduce electronic waste by up to 80%.  Userful has recently stated that in the last year their software has saved over 13,250* tons of CO2 emissions, the equivalent of taking 2,300 cars off the road.

Another approach for future Green Computing is building big more and more data centers where data center refers to a centralized repository, either physical or virtual, for the storage, management, and dissemination of data and information organized around a particular body of knowledge or pertaining to a particular business. 

Conclusion:

So far, consumers haven't cared about ecological impact when buying computers, they've cared only about speed and price. But as Moore's Law marches on and computers commoditize, consumers will become pickier about being green. Devices use less and less power while renewable energy gets more and more portable and effective. New green materials are developed every year, and many toxic ones are already being replaced by them.                         

 So green computing is a mindset that asks how we can satisfy the growing demand for network computing without putting such pressure on the environment. There is an alternative way to design a processor and a system such that we don't increase demands on the environment, but still provide an increased amount of processing capability to customers to satisfy their business needs. Green computing is not about going out and designing biodegradable packaging for products. Now the time came to think about the efficiently use of computers and the resources JIET Page 8

which are non renewable. It opens a new window for the new entrepreneur for harvesting with E-waste material and scrap computers.                     The greenest computer will not miraculously fall from the sky one day; it’ll be the product of years of improvements. The features of a green computer of tomorrow would be like: efficiency, manufacturing & materials, recyclability, service model, selfpowering, and other trends. Green computer will be one of the major contributions which will break down the 'digital divide', the electronic gulf that separates the information rich from the information poor.
