Green computing aims to reduce the environmental impact of computing through more efficient use of computing resources and recycling of electronic equipment. It involves approaches like virtualization to reduce hardware needs, power management to improve efficiency, using more energy efficient displays, and recycling materials. While green computing can help the environment, it may increase costs and equipment may be underpowered. However, as technology advances, devices are using less power while renewable energy sources improve.

- 3. What is Green Computing? Green computing is the study and practice of using computing resources efficiently. The goals are similar to green chemistry; reduce the use of hazardous materials, maximize energy efficiency during the product's lifetime, and promote recyclability or biodegradability of defunct products and factory waste.
- 4. Examples of green computing Purchasing from Environmentally Committed Companies. 1 Participating in Electronic Recycling Programs. 2 Deploying Virtual Technologies. 3 Limiting Printing and Recycling Paper. 4
- 5. Who invented Green Computing The term Green computing came into existence with the launch of Energy Star program in 1992 by U.S environmental protection agency. It aims towards electricity saving and less amount of heat generated by the computers. Widespread use of computers and related IT products has a very bad effect on the environment.
- 7. Virtualization Computer virtualization is the process of running two or more logical computer systems on one set of physical hardware. It is one of the hardware reducing , cost saving & energy saving technology. On a server or a desktop PC, it allows multiple Operating System & Application to run on a single computer. The software that makes this possible is known as Hypervisor.
- 9. Why do we need to virtualize? 1. We can run multiple servers on one single physical server thus reducing the usage of hardware and saving money. 2. We can upgrade virtual machine hardware with just a mouse click. 3. Disaster Recovery : Virtual machinery are files so the entire vm(virtual machine) can backed up.We can not only create a backup for the data but the installed programs and OS as well.
- 10. Power Management The Advanced Configuration & Power Interface(ACPI) , an open industry standard, allows an operating system to directly control the power saving aspects of its underlying hardware. Power management for computer systems are desired for many reasons, particularly: 1. Prolong battery life for portable and embedded systems. 2. Reduce cooling requirements. 3. Reduce noise. 4. Reduce operating costs for energy and cooling.
- 11. How to enable ACPI on machine Click the 'Device Manager' button Expand the Computer object Its type will be shown, probably 'Standard PC' (if it says (Advanced Configuration and Power Interface (ACPI) PC then ACPI is enabled already) Click here to view image Right click on the Computer type and select Properties Select the 'Driver' tab Click 'Update Driver' The Upgrade Device Driver Wizard will start. Click Next You can now either ask it to find a driver or manually select If you select Manual select the 'Show all hardware of this device class' and select the ACPI driver. Click Next Click Next to install the driver Click Finish to the wizard and click Close the computer property driver dialog Click Yes to restart your computer
- 12. Power Supply • Power supplies in most computers (PSUs) aren't designed for energy efficiency. In fact, most computers drain more power than they need during normal operation, leading to higher electrical bills and a more dire environmental impact. • Various initiatives are underway to improve the efficiency of computer power supplies. Climate savers computing initiative promotes energy saving and reduction of greenhouse gas emissions by encouraging development and use of more efficient Power supplies.
- 14. Storage There are three routes available, all of which vary in cost, performance, and capacity. SSDs may use more power than hard disks, (e.g., 4GBi-RAM uses more power and space than laptop drives).
- 15. GREEN STORAGE To reduce the amount of carbon dioxide released into the atmosphere as result of day to day activities of a particular organization is called green storage. The real goal of green storage is not just being environment- friendly, but also lowering costs, improving the efficiency of resources, and preserving energy.
- 16. TAPES Tapes are still a popular solution for reducing carbon footprints(carbon dioxide released) because it has no parts that uses energy and has more shelf-life(length of a time a product may be stored)than other methods of storage and it is portable. Tape systems consumes about 87% less energy than equivalent amounts of hard disk storage and can produce up to an 87% reduction in CO2 emissions. Storage Capacity – 100 MB to 200 GB This Photo by Unknown author is licensed under CC BY.
- 17. Scientists have created the largest computer chip yet to be made from carbon nanotubes: rolled up sheets of atom-thick graphene that conduct electricity at super-fast speeds. Some researchers hope to use carbon nanotubes in future computers because they conduct electricity faster and more efficiently than silicon does.
- 18. Displays LCDs are up to 66% more energy efficient than CRTs, LCDs are also upwards of 80% smaller in size and weight, leading to fuel savings in shipping. LCDs produce less heat, meaning you'll need less AC to keep cool. LCD screens are also easier on the eyes. Their lower intensity and steady light pattern result in less fatigue versus CRTs.
- 19. Why does CRT consume more power There has to be a heated filament so electrons can flow off of the cathode. There is a high voltage power supply and a yoke coil that needs power to move the electron beam back and forth on the screen. For instant on the CRT uses a small amount of power to keep the cathode warm.
- 20. Materials Recycling • Computer recycling refers to recycling or reuse of a computer or electronic Waste. This can include finding another use for the system (i. e. donated to charity), or having the system dismantled in a manner that allows for the safe extraction of the constituent materials for reuse in other products. • Additionally, parts from outdated systems may be salvaged and recycled through certain retail outlets and municipal or private recycling centres.
- 21. What is green disposal in green computing? Green Disposal: Recycling unwanted electronic equipments. Green Design: Designing energy efficient computing devices. Green Manufacturing: Manufacturing computing devices with no impact on the environment.
- 23. Implementation Blackle Fit-PC: a tiny PC that draws only 5w Zonbu Computer The Asus Eee PC and other ultra portables
- 24. Blackle Blackle is a search-engine site powered by Google 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. Based on this theory if everyone switched from Google to Blackle, mother earth would save 750MW each year.
- 25. Fit-PC: a tiny PC that draws only 5w Fit-PC is the size of a paperback and absolutely silent, yet fit enough to run Windows XP or Linux. Fit-PC is designed to fit where a standard PC is too bulky, noisy and power hungry. If you ever wished for a PC to be compact, quiet and green – then Fit-PC is the perfect fit for you. Fit-PC draws only 5 Watts, consuming in a day less power than a traditional PC consumes in 1 hour.

- 27. The Asus Eee PC and other ultra portables The "ultra-portable" class of personal computers is characterized by a small size, fairly low power CPU, compact screen, low cost and innovations such as using flash memory for storage rather than hard drives with spinning plotters. These factors combine to enable them to run more efficiently and use less power than a standard form factor laptop. The Asus Eee PC is one example of an ultraportable.
- 28. EXAMPLES • The IBM ThinkPad X40, Sony VAIO PCG-TR3A, HP Compaq NC4010 and the Gateway M200X are examples of ultraportable laptop computers.
- 29. ADVANTAGES Energy Saving Environment Friendly Less pollution Less greenhouse gas emissions
- 30. Limitations Green Computing could be quite costly. Some computers that are green may be considerably underpowered. Rapid technology change.
- 31. Conclusion Consumers haven't cared about ecological impact when buying computers, they've cared only about speed and price. But as Moore's Law marches on and computers commoditize, consumers will become pickier about being green. Devices use less and less power while renewable energy gets more and more portable and effective. New green materials are developed every year, and many toxic ones are already being replaced by them.
