WHAT IS IT????

5. 7/4/2017 5

6.  Algorithmic efficiency
 the cost of hardware has declined relative to the
cost of energy
 Virtualization
 With virtualization, several physical systems are
combined into one single system, thereby
unplugging the original hardware and reducing
power and cooling consumption.
7/4/2017 6

7.  Terminal Servers
 When using terminal servers, users connect to a
central server; all of the computing is done at
the server.
 Thin client
 Power management
 The Advanced Configuration and Power
Interface (ACPI), an open industry standard,
allows an operating system to directly control
the power saving aspects of its underlying
hardware.
 Sleep mode

8.  Energy saving Devices
 Solid State storage, LCD monitor with cold-
cathode fluorescent bulb or light-emitting diodes
(LEDs)
 Telecommuting
 Teleconference, VoIP (Voice Over Internet Protocol)
 Recycling: e-Waste

9. WHY GREEN COMPUTING???

10.  CPU uses 120 Watts
 CRT uses 150 Watts
 8 hours of usage, 5 days a week = 562 KWatts
 if the computer is left on all the time without
proper power saver modes, this can lead to 1,600
Kwatts
 for a large institution, say a university of
40,000 students and faculty, the power bill
for just computers can come to $2 million /
year.
7/4/2017 10

11.  Energy use comes from
 electrical current to run the CPU, motherboard,
memory
 running the fan and spinning the disk(s)
 monitor (CRTs consume more power than any
other computer component)
 printers
7/4/2017 11

12.  Use hardware/software with the Energy Star
label
 Energy Star is a “seal of approval” by the Energy
Star organization of the government (the EPA)
 Don’t print unless necessary and you are
ready
 Use LCDs instead of CRTs as they are more
power efficient
7/4/2017 12

13.  Turn off the computer when not in use, even if just
for an hour
 Turn off the monitor when not in use (as opposed to
running a screen saver)
 Use power saver mode
 in power saver mode, the top item is not
necessary, but screen savers use as much
electricity as any normal processing, and the
screen saver is not necessary on a flat panel
display

14.  IN 1992 U.S. ENVIRONMENTAL PROTECTION
AGENCY LAUNCHED ENERY STAR , THIS RESULT
IN THE WIDERSPRESD ADOPTION OF SLEEP
MODE CONSUMER ELECTRONICS
 THE TERM GREEN COMPUTING WAS PROBABLY
COINED SHORTLY AFTER THE ENERGY STAR
PROGRAM BEGAN

15. BLACKLE
ZONHU
COMPUTER
SUNRAY
THIN
CLIENT
7/4/2017 15

16.  IT IS A SEARCH-ENGINE POWERED BY GOOGLE
 WHEN COMPUTER SCREEN IS WHITE THEN IT
CONSUME 74W AND WHEN IT’S SCREEN IS BLACK
THEN IT CONUME 59 W
 IF EVERYONE SWITCH FROM GOOGLE TO BACKLE
THEN OUR EARTH WOULD SAVE 750MV EACH
YEAR.

17. 7/4/2017 17

18.  IT IS A VERY NEW AND VERY ENERGY EFFICIENT
P.C.
 CONSUM 1/3RD OF POWER OF A TYPICAL LIGHT
BULB.
 YOU CAN GET ONE AT US 99$ BUT IT REQUIRED
YOU TO SIGN UP FOR A 2YR SUBSCRIPTION
7/4/2017 18

19.  Sun Microsystems is reporting increased customer
interest in its Sun Ray, a thin desktop client, as
electricity prices climb.
 Thin clients like the Sun Ray consume far less
electricity than conventional desktops.
 A Sun Ray on a desktop consumes 4 to 8 watts of
power, because most of the heavy computation is
performed by a server.

Role Of IT Vendors
APPLE
GOOGLE
WIPRO

22.  1.Product design: It all begins here. Reducing the
environmental impact of our products starts with the
product design phase. Design dictates the quantity of raw
materials as well as the type and recyclability of materials
used. It also determines how much energy is consumed
during manufacturing and product use. For example, the
amazingly slim 20-inch iMac is made from highly
recyclable glass and aluminum and it is so energy
efficient it consumes about the same amount of power as a
standard light bulb when on.

2.Materials:
Apple helps to safeguard the environment - as well as
consumers‘ safety – by restricting the use of environmentally
harmful compounds in our materials and manufacturing
processes. In addition to the substances that have already been
restricted or eliminated, Apple is removing elemental forms of
bromine and chlorine from our products, not just polyvinyl
chloride (PVC) and brominated flame retardants (BFRs). The
new MacBook family also uses mercuryfree light-emitting
diode (LED) displays, with arsenic-free display glass.

3.Energy efficiency:
A devices greatest contribution to greenhouse gas
emissions comes from its consumptions of energy over
time. Apple has made great strides in recent years to
optimize the energy efficiency of our hardware and
created tool, such as the Energy Saver feature in Mac
OS X, that allow consumers to manage the power
consumption of their computers. Since 2001, Apple
desktop computers, portable computers, and displays
have earned the ENERGY STAR rating.

25. 7/4/2017 25
4.Recycling :
Apple‘s holistic, lifecycle approach to recycling includes
using highly recyclable materials in products in addition
to providing extensive take-back programs that enable
consumers and businesses to safely dispose of used
Apple equipment. Since first take-back initiative began
in Germany in 1994, where 95 percent of the countries
where apple products are sold - diverting over 53million
pounds of electronic equipment from landfills
worldwide. Apple is on track to eliminate toxic
chemicals from our products

GOOGLE
Google's mission is to organize the world's information and
make it universally accessible and useful. Hundreds of millions
of users access our services through the web, and supporting
this traffic requires lots of computers. We strive to offer great
internet services while taking our energy use very seriously.
That 's why, almost a decade ago; they efforts to make there
computing infrastructure as sustainable as possible. Today
they are operating what they believe to be the world's most
efficient data. In fact, in the time it takes to do a Google
search, your own personal computer will use more energy than
we will use to answer your query.

WIPRO
Wipro Limited, a leading player in Global IT and R&D services,
is committed towards environmental sustainability by
minimizing the usage of hazardous substances and
chemicals which have potential impact on the ecology. It has
joined hand swith WWF India, one of the largest conservation
organizations in the country, to directly deal with issues of
climate change, water and waste management and biodiversity
conservation.
