3. INTRODUCTION
 Green computing is the environmently
responsible use of computer and related
resources .
 The study and practice of designing
manufacturing .useing desposing of computers.
Servers.and associated subsystem efficiently
and effectively with no impact on the
environment.

4. ENERGY STAR
 One of the first manufacturing of the green
computing movement Environmental
Protection Agency (EPA) was the launch of
energy star in 1992.
 The term GREEN COMPUTING was coined
shortly after energy star began.
 Energy star applied to products like
computers monitors, televisions sets and
temperature control devices like
refrigerators, air conditioners, and similar
items.

5. NEEDS OF GREEN COMPUTING
 Computer Energy is often Wasteful.
 Printing is often Wasteful.
 Pollution.

6. COMPUTER ENERGY IS OFTEN WASTEFUL
 Leaving the computer on when not in use(CPU)
and it can consume power, screen savers consume
power.
 As we know that plastic is a hazardous material,
but the electronic waste (E-waste) is more
hazardous than the plastic.

7. PRINTING IS OFTEN WASTEFUL
 How many of you print out your emails or meeting
agendas.
 Printing out partial drafts.
 For a 3’paperless’society,we tend to use more
paper today than before computer-prevalence.

8. POLLUTION
 E-Waste: After the disposal of electronic waste (E-waste)
it produces pollution to the environment ultimately that
makes toxicity.
 Toxicity :There are toxic chemicals used in the
manufacturing of computer and components.

9. APPROACHES
 Virtualization.
 Power supply.
 Video card.
 Display.

10. VIRTUALIZATION
 Virtualization :Duplicating hardware with
software.
 Realizing a piece of hardware such as web
server or file server in software rather than
hardware writing a program that does the
same exact thing as of hardware.
 Effect of virtualization:
255 servers -> 22 Servers only
 This has resulted in a saving of almost 50-
70% of energy can be saved from
virtualization.

11. POWER SUPPLY
 A power supply is an internal hardware component
that supplies component in a hardware with power.
 A power supply converts a 110-115 or 220-230 volt
alternating current (AC into a steady low-voltage
direct current (DC).
 Power supplies include simplicity, reliability ,noise
levels and low cost.)

12. VIDEO CARD
A fast GPU may be the largest power consumer in a
computer
Energy efficient display option include:
 No video card-use a shared terminal, shared thin
client,or desktop sharing software if display
required.
 Use motherboard video output –typically low 3d
performance and low power.
 Reuse an older video card that uses little
power,many do not require heat sinks or fans.
Select a GPU based on average wattage or
performance per watt.

13. DISPLAY
 Blackle is a search-engine site powered by Google
custom search.
 Blackle came into being based on the concept
that when a computer screen is white, presenting
an empty word page or the Google home page,
your computer consumes 74W.
 When the screen is black it consumes only 59W.

15. CHALLENGES IN GREEN COMPUTING
 Equipment power density/Power and cooling capacities.
 Increase in energy requirements for data centres and
growing energy cost.
 Control on increasing requirements of heat removing
equipment.
 Which increases because of increase in total power
consumption by IT equipments.
 Equipment life cycle management-Cradle to Grave.
 Disposal of Electronic Wastes.

16. BENEFITS
 Reduces the amount of pollutions in the
surroundings.
 It saves the power consumption and reduces the
amount of heat produced from the electronics.
 It reduces the burden on paper industry.
 Encourage the use of Renewable Resources.
 Promotes effective utilisation of natural
resources.

17. STEPS TO GO GREEN
GREEN USE:
 Reducing the energy consumption of computers and other
information systems.
GREEN DISPOSAL:
 Reduction of waste ,reuse and refurbishment of hardware
and recycling of out of use peripherals and other items.
GREEN DESIGN:
 Designing energy-efficient and environmentally sound
components, computers ,servers , cooling equipment and
data centres .
GREEN MANUFACTURING:
 Manufacturing electronic components, computers and
other subsystems with minimal impact on the
environment.

18. CONCLUSION
 The green technology doesn’t include green computing only but
also focuses on the components used in the computer.
 As, energy star is used nowadays focuses on the computer does
not affect the environment.
 Green computing represents a responsible way to address the
issue of global warming.
 By adopting green computing practices, business leaders can
contribute positively to environmental stewardship and protect
the environment while also reducing energy and paper costs.
 Nowadays, every computer manufacturing company is focusing on
the green IT concept.
 However, this reality does at least mean that a widespread mind
set already exists for both adapting to and paying money for new
computer hardware on a regular basis.
