4. What is Green Computing? Green computing or green IT , refers to environmentally sustainable computing or IT. It is "the study and practice of Designing, Manufacturing, Using, and Disposing of computers, servers, and associated subsystems efficiently and effectively with minimal or no impact on the environment . 4

5. 5 Source: Conceptualizing “Green IT” & data center power and cooling issues, Gartner Research paper No G00150322 Total CO 2 emission in the world CO 2 emission caused by IT field What is Green Computing?

6. How Computing Harm Environment Cost of Spam 62 trillion spam messages in 2014 0.3 grams of carbon dioxide (CO2) per message annual spam energy use 33 terawatt hours ( tWh ) equivalent to the electricity used in 2.4 million homes every year The CO2 dissipated from ‘sleeping’ devices = 1/7th the CO2 emitted by an automobile . 6

7. How Computing Harm Environment Increase in power, cooling and space for data center. 2007-$4.5 billion of electricity 2011-$7.4 billion of electricity 2011-Double CO2 output ( 62 million metric tons) 7

8. How Computing Harm Environment By electronic appliances. Desktop requires 85 watts just to idle(Monitor off) Left on 24 hrs /day-1,500 pounds of CO2 per year. A tree absorbs between 3 and 15 pounds of CO2 each year.(up to 500 trees) 8

9. How Computing Harm Environment Hazardous materials inside computers. These contain Cadmium- damage kidneys Mercury- neurological damage Lead- disrupt brain neurotransmitters 9

10. Objectives of Green Computing Reduce climate change Savings Reliability of Power Computing Reduce the use of hazardous materials 10

11. Climate Change : First and foremost, conclusive research shows that CO2 and other emissions are causing global climate and environmental damage. Preserving the planet is a valid goal because it aims to preserve life. Planets like ours, that supports life, are very rare. 11 Objectives of Green Computing

12. Savings : Green computing can lead to serious cost savings overtime. Reductions in energy costs from servers, cooling, and lighting are generating serious savings for many corporations. maximize energy efficiency during the product’ s lifetime promote the recyclability or biodegradability of defunct products and factory waste.   12 Objectives of Green Computing

13. Reliability of Power : As energy demands in the world go up, energy supply is declining or flat. Energy efficient systems helps ensure healthy power systems. Computing : Computing Power Consumption has Reached a Critical Point. Data centers have run out of usable power and cooling due to high densities . 13 Objectives of Green Computing

14. Approaches to Green Computing: 1. Virtualization : Computer virtualization is the process of running two or more logical computer systems on one set of physical hardware.   14

15. 2. Power Management : ACPI allows an operating system to directly control the power saving aspects of its underlying hardware. Prolong battery life for portable and embedded systems. Reduce cooling requirements. Reduce noise. Reduce operating costs for energy and cooling 15 Approaches to Green Computing:

16. 3. Video Card : A fast GPU-largest power consumer No video card – use a shared terminal 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. 16 Approaches to Green Computing:

17. 4. Telecommuting : Reduction of greenhouse gas emissions related to travel and increased profit margins. Increased worker satisfaction . 17 Approaches to Green Computing:

18. Simple Tasks we can do.. Buy and use a low power desktop or a laptop computer (40-90 watts) rather a higher power desktop (e.g. 300 watts). Buy hardware from manufacturers that have a hardware recycling scheme , and recycle your old computer equipment rather than sending it to landfill. Replace your CRT screen with an LCD screen. 18

19. Power Consumption in An Average Laptop 19 Display needs the maximum power consumption in a laptop.

20. 20 Turn your computer and monitor off when you are not using it. Enable hibernation using the power management settings. Standby does not save as much power. Use Linux (such as Ubuntu), which requires less resources than many other operating systems . Simple Tasks we can do..

21. Advantages Energy saving Environmentally Friendly Cost-effective ( pays over time ) Save more money per year Can give you a tax right off 21

22. Disadvantages: High start up cost Not readily available Still in experimental stages Sacrifieses performance for battery life Not for everyone 22

23. Conclusion So far, consumers haven’ t cared about ecological impact when buying computers, they’ve cared only about speed and price . Green computing can lead to a lot of energy savings, reduction in emission of co2 & CFC’s which leads to environment protection. It also leads to serious cost savings overtime. The features of a green computer of tomorrow would be like : efficiency, manufacturing and materials, recyclability, server model , self-powering and other trends . 23
