This document discusses green computing and its focus on energy efficiency and reducing e-waste. It introduces green computing and defines it as the environmentally responsible use of computers and resources. It discusses approaches to green computing like virtualization, power supplies, video cards and displays. It covers the needs of green computing in reducing wasteful computer energy and printing and pollution from e-waste. Challenges and benefits of green computing are presented, along with steps to implement green computing practices.

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.
