This document defines green computing and discusses its importance. Green computing aims to reduce the environmental impact of computing through more efficient use of resources and responsible disposal of electronic waste. It involves strategies like power management, using energy efficient hardware, recycling electronics, and reducing paper usage. While green computing requires initial costs, it provides long term benefits like financial savings, energy efficiency and environmental protection. The document emphasizes that adopting green computing practices is important for a sustainable future.

3. Is that Cloud computing is an Internet service that provides
computing needs to computer users. Green computing is that a
computer and technology is how much responsible for
environmental change.
Cloud Computing: Cloud computing is an Internet service that
provides computing needs to computer users. When the company
uses the computing resources, they pay a fee based on the amount
of computing time and other resources that they consume. Cloud
computing allows a company to diversify its network and server
infrastructure. Some cloud computing services automatically add
more network and server capacity to a company’s Web site, as
demand for services of the Web site increases.

Difference Between Cloud Computing and Green Computing

4. Green Computing:
Green computing is that a computer and technology is how much
responsible for environmental change. A typical desktop computer
and 17-inch monitor that always are turned on release 750 pounds
of carbon dioxide in one year, which is the same amount of carbon
dioxide released by a car driven 820 miles. Power management
software helps conserve a computer’s electricity consumption while
maintaining acceptable performance. The programs determine
when a computer is inactive and, in turn, power down the computer.
Use one of the search engines listed or your own favorite search
engine to find information about power management software.

5. 4 Reasons Why Cloud Computing is Also a Green Solution
1. Resource virtualization, enabling energy and resource
efficiencies.
2. Automation software, maximizing consolidation and utilization
to drive efficiencies.
3. Pay-per-use and self-service, encouraging more efficient
behavior and life-cycle management.
4. Multitenancy, delivering efficiencies of scale to benefit many
organizations or business units.

6. DEFINITION - WHAT DOES GREEN COMPUTING
MEAN?
 Green computing practices came in 1992, when the
Environmental Protection Agency (EPA) launched the
Energy Star program.
 Green computing is also known as green
information technology (green IT).
 Green IT :-Green computing is the
environmentally responsible and eco-friendly use
of computers and their resources.

7. WHY GREEN COMPUTING ?
 As we are familiar that plastic is a hazardous material, butthe
electronic wastes (E-Waste ) is more hazardous than the plastic.
 The development and fabrication of an electronic device, we use
different kind of materials such as arsenic, antimony, lead
, cadmium etc.
 The U.S. generates more than 2 million tons of e-waste
annually, and nearly 90 percent of that ends up in landfills
 Disposal of such materials causes harm to the nature and
environment :THAT’S THE MAIN RESON OF GREEN
COMPUTING ESTABILISHMENT….

8. ROADS TO GREEN COMPUTING :
 Green use: Minimizing the electricity consumption.
 Green disposal: Re-making an existing computer or
recycling, unwanted electronic equipments.
 Green design: Designing energy-efficient
computers, and other digital devices.
 Green manufacturing: Minimizing waste during the
manufacturing of computers and other subsystems to
reduce the environmental impact of these activities.

9. GENERAL TACTICS TO MAKE COMPUTING USAGE MORE GREEN:
 Turn off computers at the end of each day.
 Use power saver mode.
 Use liquid-crystal-display (LCD) monitors rather than cathode- ray-
tube (CRT) monitors.
 Don’t print unless necessary .
 Dispose of e-waste according to federal, state andlocal
regulations.
 Instead of purchasing a new computer, try refurbishingan
existing device.
 Use hardware software with a energy starlabel.

10. STRATEGIES WHICH HELP IN IMPLEMENTATION OF
GREEN COMPUTING
 Replacing Paper Systems with On-line Communication Systems.
 Power Management
 Power supply
 Algorithmic efficiency
 Terminal Servers/Serial server
 Storage
 Operating system issues
 Materials recycling
10

11. GREEN DISPOSAL
 Reuse:- donate your computer components to people who may
not have or have lesser quality computers.
 Refurbish: rather than discarding your computer upgrade it.
change its some of the parts in order to make itnew.
 Recycle

12. HOW TO SAVE ENERGY WHILE WORKING ON
THE INTERNET:
 Blackle is the website powered by Google custom search
and created by Heap Media, which aims to save energy
by displaying a black background and using grayish-
white font color for search results.
 Blackle saves energy because the screen is
predominantly black.
 Set blackle as your homepage.

13. ENERGY USE OF PC
 CPU uses 120 watts
 CRT uses 150 watts
-8 hr of usage,5 days a week =562 K watts.
 Energy use comes from:-
 Electrical current to run the
CPU, motherboard, memory.
 Monitors
 printers
13

14. GREEN MANUFACTURING
 Recyclable plastics : computers are constructed
from non-recyclable plastics ,i.e. Recyclable
polycarbonates resin.
 Volume reduction : remove hazardous portion of
waste from non hazardous portion.
 Bamboo : is becoming increasingly popular for
making casings for computers and peripherals.

15. EXAMPLES OF BAMBOO USAGE :-

16. Advantages:
 Energy saving Environmentally Friend.
 Save more money per year.
 Green computing techniques will actually translate
into a much lower carbon dioxide emission
Disadvantages:
 High start up cost.
 Still in experimental stages.

17. CONCLUSION
 Adopting Green Computing Strategies make sense not only from an
ethical, or moral stand-point, but from a commercial stand-point.
 There are many business benefits achievable through the
implementation of a green computing strategy such as cost
savings, resilience, disaster recovery, business continuity
planning and of course public relations.
 Green computing is the utmost requirement to protect environment
and save energy along with operational expenses in today's
increasingly competitive world. Adopting a holistic approach to
greening IT is our responsibility towards creating a more
sustainable environment.

18. Questions
1. What we are doing/ will do for the environments?
2. Why screen saver is not effective now a day ?
3. Is Green Computing is effective for future point of view?
We all have responsibilities for the environment Protection!
