Green Computing
Mandanikashmira, Chohala Meera
Green Computing is called as Green IT.It’s
environment friendly IT where the main Objective is to reduce the
hazardous materials and maximize the
energy efficiency.It means "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 systems — efficiently and
effectively with minimal or no impact on the environment." The goals of
green computing are similar to green chemistry; reduce the
use of hazardous materials, maximize energy
efficiency during the product's lifetime, and promote the recyclability or biodegradability of defunct products and factory waste.
-Computer consumes a lot of energy.
-so, we must have to reduce the power consumption
and thus reduce the global warming.
-to reduce pollution
-to reduce toxicity.

What
is different about “Green”?
One cannot achieve a Sustainable Strategy with a product, it takes
an Architectural commitment.
-The corporate architect must realize that the impact corporations
make on the environment now is engrained in doing business:
-Executives are allocating time,
energy and money to invest in environmental initiatives.
-Governments are allocating
research and regulations, and laws are being written to address the efficiency of data centers
and other critical components of IT infrastructure.
- Consumer advocates, policy makers and influential industry
leaders are promoting IT organizations to significantly confront the impact
that computing and electronics make on the environment.
-This is a vastly different landscape than for other galvanizing
themes such as SOA, agile design, or Web 2.0 and SaaS. Those themes did not
elicit the same degree of regulatory, legal, and advocacy. Ten years from now,
those initiatives may not exist in their present incarnation, but commitments
to reduce environmental impact and power consumption will continue to be
-important objectives for organizations.
-As
the commitment to reduce environmental impact and power consumption are
becoming increasingly important objectives for organizations, architecture
leaders are now proactively considering environmental resource constraints
along with more traditional IT business goals.
-Rather
than viewing the environmentally sustainable data center as a product feature
checklist for a onetime win, serious IT architects are adopting a more
comprehensive sustainability plan in their data center system design. While new
technology from the industry
-continues
to drive efficiency into the IT infrastructure,

Energy
consumption by computer
-CPU uses 120 watts
-CRT uses 150 watts
-Energy use comes from
*
electric current to run CPU , motherboard, memory.
*
Running the fan & Spinning the disk.
*
Monitor(CRT consumes more power than
any other computer component.)
*
Printers.

Problems
and causes with computers on global warming
1.
Leaving the
computer when in not use..
(Screen savers, CPU, Fan consumes more power)
2.
Printing is often wasteful
We are used
to printout our works.
3.
Pollution
via electronics
Manufacturing
techniques
Packaging
Disposals
of computer parts or any electronic item part..
4.
Toxicity
There are
many toxic materials used in computers. But two materials are very toxic.
Problems:
•
Cause
damage to nervous system , blood system , kidneys, and also cause negative
effects on child brain development
• Also has toxic effects on plants, animals and
microorganisms .
•
can
cause chronic brain damage.

Solution
ü Keep PCs
turned off, when not in use.
ü Disable screen saver.
ü Don’t print until
it is necessary.
ü Use LCDs
instead of CRTs as they are more power efficient.
ü Use hardware/software with “energy star” label. It is the “seal of
approval” by Energy Star Organization of the government.
ü Set low power “Sleep” mode.
-can still download and perform other routines.
ü Stand By
-it is energy conserving because switches to a “low
power state.”
ü Hibernate
-It writes an image of what you are currently working
on your file/hard drive and then shutts your
PC almost completely off.
ü Use Email to reduce paper work
ü Add: “*Please Consider the environment: Do U
really need to print this mail?*”
(put
entire message in Subject line.)
ü Place Information web-page, wikis instead of
making paper copies.
(online resource consume 90% less energy and produce
85% fewer co2 emissions.)
ü Recycling E-waste:
ü Developed countries have now facility of recycling
e-waste.

ü Being Green with Yahoo!
