What is Green Computing?

Green computing orgreen IT, refers to

environmentally sustainable computing or IT.

It is "the study and practice of Designing,

Manufacturing, Using, and Disposing of

computers, servers, and associated subsystems

efficiently and effectively with minimal or no

impact on the environment.

Why Go For Green Computing

Today, the main problem of the world is

Global warming.

The atmosphere is becoming hot & is causing

many problems to living organisms.

Computers also play a major role in polluting

the world.

Increase in power, cooling and space for data

center.

2007-$4.5 billion of electricity

2011-$7.4 billion of electricity(25 power

plants)

2011-Double CO2 output ( 62 million metrictons)

By electronic appliances.

Desktop requires 85 watts just to idle(Monitor

off)

Left on 24 hrs/day-1,500 pounds of CO2 per

year.

A tree absorbs between 3 and 15 pounds ofCO2 each year.(up to 500 trees)

According to reports from the German Federal

Environment Office, devices consume around

17 billion (kWh) in a year in standby mode.

The CO2 dissipated from sleeping devices =

1/7th the CO2 emitted by an automobile.

Manufacturers do not provide a proper shut-off

button in devices.

Windows Vistas default shut down mode is a

deep sleep mode that requires power.7

Hazardous materials inside computers.

These contain

Cadmium(damage your kidneys)Mercury(neurological damage)

Lead(disrupt brain neurotransmitters).

Origin

In 1992, the U.S. Environmental Protection Agency

launched Energy Star, a voluntary labelling program

which is designed to promote and recognize energy-

efficiency in monitors, climate control equipment,and other technologies.

Saved $14 billion in energy costs in 2006 alone.

Widespread adoption of sleep mode

EPEAT, is focused on promoting energy efficient

products.

Virtualization:

It includes Server virtualization,

Consolidation, Storage consolidation &

Desktop virtualization.

Our typical computer used up to a 250-watt

power supply; our thin client uses a 4.8-watt

power supply.

11

Power management:

Prolong battery life.

Reduce cooling requirements.

Reduce noise.

Reduce operating costs for energy and cooling.

Lower power consumption.

The ACPI, an open industry standard

Under volting programs

Storage:

Among 3.5" desktop hard drive, 2.5" laptophard drive and a solid state hard drive (SSD);

(SSD) consumes less power than other disks.

13


14/30


Display:

LCD displays: use a CCF bulb

LED displays: use an array of LEDs

LCD monitors uses 3 times less when active,

and 10 times less energy when in sleep mode.

LCDs are up to 66% more energy efficient. LCDs are also smaller in size and weight.

21" CRT typically uses more than 120W.

IT Equipment Recycling:

If you can extend the working life of your ITproducts, you reduce the environmental

consequences of mining, manufacture,packaging, shipping and disposal.

Many organizations, including somemanufacturers themselves, are willing to take

equipment back and recycle the componentsinto new products.

Product Longevity:

Gartner maintains that the PC manufacturing

process accounts for 70 % of the natural

resources used in the life cycle of a PC.

Another report from Gartner recommends to

"Looking for product longevity, including

upgradability and modularity."

Remote Conferencing & Telecommuting Strategies:

Given recent jumps in fuel costs and greater

awareness of harm caused by greenhouse gas

emissions, many companies wish to reduce travel tocut costs and decrease negative impact on the

environment.

The initiatives in this study consist of the following: Remote Conferencing & Collaboration.

Video-conferencing and teleconferencing.

Operating System Support:

Windows 7 includes refinements for more efficient

user of operating system timers, processor power

management, and display panel brightness. Linux Os utilizing less resources than other os, and

also have a better power management facility.

Terminal servers: Terminals can be combined with thin clients, which

use up to 1/8 the amount of energy of a normal

workstation.

19/30


Algorithmic efficiency:

The Efficiency of algorithms is used to describeproperties of an algorithm relating to how much

resources it consumes. Algorithms are the base of any computing system

or electronic device, each and every computerchip has a certain algorithm that allows it to

complete its function. Even though these chips are small, they use a lot

of power.

19


20/30


Buy and use a low power desktop or a laptop

computer (40-90 watts) rather a higher power desktop

(e.g. 300 watts).

Thin clients can use only 4 to 8 watts of power at thedesktop as the processing is done by a server.

Buy hardware from manufacturers that have a

hardware recycling scheme, and recycle your old

computer equipment rather than sending it to landfill.

20


21/30


Turn your computer and monitor off when you

are not using it.

Enable hibernation using the power

management settings. Standby does not save as

much power.

Replace your CRT screen with an LCD screen.

Save Your Paper!

Green Print Saves Too!

21


22/30


Use Linux (such as Ubuntu), which requires

less resources than many other operating

systems on an older computer as a spare or a

file server. Use blade servers instead of rack or standalone

servers to reduce power consumption.

Steps by Apple

MacBook keyboards are made from one single

piece of aluminum

MacBook pro notebooks have long lasting

batteries where as a normal notebook uses

three batteries a MacBook will only use one

through out its life time.

Steps by DELL

Their free world-wide product recycling

program allows user to properly dispose their

product safely.

Their Plant a tree for me project can offset a

customers carbon emissions for only three

dollars.

Conclusion

Green computing can lead to a lot of energy

savings, reduction in emission of co2 & CFCs

which leads to environment protection.

It also leads to serious cost savings overtime.
