remain suspended in the environment like
an ordinary dust particle.
the air currents can also move them in
the direction of flow.
It is very hard to detect the presence of
the Smart Dust and it is even harder to
get rid of them once deployed.

32. WHAT IS CLOUD COMPUTING?
Cloud computing is a model for enabling convenient, on-
demand network access to a shared pool of configurable
computing resources like networks, servers, storage,
applications, and services.
33. Cloud Advantages
Reduce spending on technology infrastructure. Maintain easy access to
information with minimal upfront spending. Pay as you go based on
demand.
Globalize your workforce on the cheap. People worldwide can access
the cloud, provided they have an Internet connection.
Reduce capital costs. There’s no need to spend big money on hardware,
software or licensing fees.
Improve accessibility. You have access anytime, anywhere, making your
life so much easier!
Minimize licensing new software. Stretch and grow without the need to
buy expensive software licenses or programs.
Improve flexibility. You can change direction without serious financial
issues at stake.
34. Dark side of Cloud
• Gartner Report 2007: IT industry contributes 2% of world's
total CO2 emissions
• 1.5% of total U.S. power consumption is used by data
centers which has more than doubled since 2000 and costs
$4.5 billion
35. Sustainability and Green IT?
35
A pile of electronic waste on a roadside in Guiyu, China
Electronic waste in Guangdong, China As much as
4,000 tonnes of toxic e-waste are discarded eve
ry hour. Vast amounts are routinely and often ille
gally shipped as waste from Europe, USA and Jap
an to places where unprotected workers recover
parts and materials.
36. Clouds Impact on the Environment
Data centers are not only expensive to maintain, but also
unfriendly to the environment.
Carbon emission due to Data Centers worldwide is now
more than both Argentina and the Netherlands emission.
High energy costs and huge carbon footprints are incurred
due to the massive amount of electricity needed to power
and cool the numerous servers hosted in these data centers.
37. Why is green computing needed in cloud?
Cloud Data Centers consume excessive amount of
energy:
• A typical data center consumes as much energy as
25,000 households.
• The total energy bill for data centers in 2010 was over
$11 billion and energy costs in a typical data center
doubles every five years.
38. WHAT IS GREEN COMPUTING?
Green computing is the environmentally responsible and
eco-friendly use of computers and their resources. In
broader terms, it is also defined as the study of designing,
manufacturing, using and disposing of computing devices in
a way that reduces their environmental impact.
Green Cloud computing is envisioned to achieve not only
efficient processing and utilization of computing
infrastructure, but also minimize energy consumption.
39. Roads to Green Computing
Green Use Green Manufacturing
Green Design
Green Disposal
Four
domains
of
Green
Computing
40. Green use is all about reducing the energy
consumption associated with the computing resources
and use them in an environmentally sound manner.
Green Design - designing energy-efficient and
environmentally sound components, computers, servers,
cooling equipment, and data centers
Green Manufacturing - manufacturing electronic
components, computers, and other associated
subsystems with minimal impact on the environment
Green disposal deals with the issues of refurbishing
and recycling old computers and electronic equipment.
41. Cloud Providers Measures
Cloud service providers need to adopt measures to ensure
that their profit margin is not dramatically reduced due to
high energy costs.
Amazon.com’s estimate the energy-related costs of its
data centers amount to 42% of the total budget that
include both direct power consumption and the cooling
infrastructure amortized over a 15-year period.
Google, Microsoft, and Yahoo are building large data
centers in barren desert land surrounding the Columbia
River, USA to exploit cheap hydroelectric power.

Green Computing Initiatives
As part of a green strategy, IT organizations should assess which
tech manufacturers have taken an environmentally conscious
approach in their product design and are working to reduce their
carbon footprint in their manufacturing processes.
Such practices include the implementation of energy-efficient
central processing units (CPUs), servers and peripherals as well as
reduced resource consumption and proper disposal of electronic
waste (e-waste).
Enterprise Management Associates (EMA) recommends businesses
to implement a green computing solution not only to contribute to
the global environmental movement, but also to de-crease operating
expenses and boost profitability
43. Lenovo has developed new energy-efficient LCD monitors that
reduce the number of lamps from four to two.
Xerox has developed green printers that use solid ink, which produce
less waste because IT administrators no longer have to dispose of
toner cartridges.
Hewlett-Packard’s DeskJet D2545 printer relies heavily on recycled
materials
Recycled plastics account for 83 percent of the printer’s total plastic
weight, and it uses ink cartridges molded from recycled plastic resins.
The printer is also Energy Star certified and comes in 100 percent
recyclable packaging.
Some tech manufacturers are trying to make their packaging 100
percent recyclable.
Acer is reducing its use of plastic foam. Acer’s Aspire Netbooks ship
primarily in cardboard packaging.

44. Tips for Initiating Green Strategy
Review your document on the screen instead of printing a draft. If you
must print a draft, use the blank back side of used sheets. It may be
possible to keep once-used paper in an extra tray in your printer.
Print in Economic mode when you can this saves toner by printing
lighter on paper.
Print duplex this saves paper.
Only buy a monitor as large as you really need.Although a large monitor
might seem more attractive, you should remember that a 19-inch
monitor uses 40% more energy than a 17-inch monitor.Also, the higher
the resolution you buy, it needs more energy.
Again, the biggest thing is turning off all equipment when you leave for
the day computers, monitors, copiers, printers, fax machines, etc.
Change your default margins in MS Word—The current margin default
settings of 1.25" left/right and 1" top/bottom "eat up" a lot of usable
document space.

45. Using Virtualization to Reduce Numbers of Servers
Virtualization is the technology, which allows companies’ business
application to be managed by independent host’s hardware.
Where servers are typically underutilized, virtualization can be used
to carve up a single physical machine into a number of virtual servers.
From a green perspective the net result is normally a substantial
reduced in power and air conditioning requirements saving energy,
money and thus reducing the carbon footprint of the server estate.

used for pest detection.
◦ Airborne imaging systems
offer advantages over satellite
due to relatively low cost, high
spatial resolution, easy deploy-
ment and real time availability
of imagery for visual use. Nikon camera mounted on the step of an ag
aircraft. A GPS receiver and video monitor
integrated with the camera are mounted in the
cockpit.
59. Proposed UAV Uses Being Conducted Now by Manned Aircraft &
Satellites
Aerial Imaging
◦ Software can be used to
perform basic image pro-
cessing and create pre-
scription maps for precision
application.
◦ UAS are another tool that
can collect these images
and data for precision ag
A color image acquired at 4,000 ft.AGL over a cotton field
infected with cotton root rot using an ag aircraft. On the
color image, healthy cotton plants have a dark green color,
whereas infected plants have a grayish tone similar to bare
soil.
60. UAVs Used for Aerial Application Purposes
UAVs in Japan
◦ 90 percent of crop protection in
Japan is performed by UAVs (4
gallon RMAX helicopter)
◦ Average farm size in Japan is 1.5
hectares (3.7 acres), compared to
441 acres in the US.
◦ RMAX spraying speed 15 mph vs.
160 mph for a manned ag aircraft
