  4. 4. <ul><li>What is Green computing? </li></ul><ul><li>Green computing is the study and practice of using computing resources efficiently. </li></ul><ul><li>Green computing is the environmentally responsible use of computers and related resources. Such practices include the implementation of energy-efficient central processing units (CPUs), servers and peripherals as well as reduced resource consumption and proper disposal of electronic waste (e-waste). </li></ul>
  5. 5. Roads to Green Computing <ul><li>T o effectively address the environmental impacts of computing/IT, we must adopt a holistic approach and make the entire IT lifecycle greener by addressing environmental sustainability along the following four complementary paths: </li></ul><ul><li>Green use -- reducing the energy consumption of computers and other information systems as well as using them in an environmentally sound manner. </li></ul>
  6. 6. <ul><li>Green disposal -- refurbishing and reusing old computers and properly recycling unwanted computers and other electronic equipment. </li></ul><ul><li>Green design -- designing energy-efficient and environmentally sound components, computers, servers, cooling equipment, and data centers. </li></ul><ul><li>Green manufacturing -- manufacturing electronic components, computers, and other associated subsystems with minimal impact on the environment. </li></ul>
  7. 7. Origin <ul><li>In 1992, the U.S. Environmental Protection Agency launched Energy Star , a voluntary labeling program which is designed to promote and recognize energy-efficiency in monitors, climate control equipment, and other technologies. </li></ul><ul><li>This resulted in the widespread adoption of sleep mode among consumer electronics. </li></ul><ul><li>The term &quot;green computing&quot; was probably coined shortly after the Energy Star program began. </li></ul>
  8. 8. Energy Star <ul><li>ENERGY STAR is an international standard for energy efficient consumer products. </li></ul><ul><li>It was first created as a United States government program in 1992, but Australia, Canada, Japan, New Zealand, Taiwan and the European Union have also adopted the program. </li></ul><ul><li>Devices carrying the Energy Star logo, such as computer products and peripherals, kitchen appliances, buildings and other products. </li></ul>
  9. 9. <ul><li>The Swedish organization TCO Development launched the TCO Certification program to promote low magnetic and electrical emissions from CRT-based computer displays. </li></ul><ul><li>This program was later expanded to include criteria on energy consumption, ergonomics , and the use of hazardous materials in construction. </li></ul>
  10. 10. <ul><li>Regulations and industry initiatives </li></ul><ul><li>Government </li></ul><ul><li>Many governmental agencies have continued to implement standards and regulations that encourage green computing. </li></ul><ul><li>The Energy Star program was revised in October 2006 to include stricter efficiency requirements for computer equipment, along with a tiered ranking system for approved products. </li></ul>
  11. 11. <ul><li>The European Union's directives on the reduction of hazardous substances, and on waste electrical and electronic equipment (WEEE) required the substitution of heavy metals. </li></ul><ul><li>flame retardants like PBBs and PBDEs in all electronic equipment put on the market starting on July 1, 2006. </li></ul><ul><li>There are currently 26 US States that have established state-wide recycling programs for obsolete computers and consumer electronics equipment. </li></ul>
  12. 12. Industry <ul><li>Climate Savers Computing Initiative (CSCI) is an effort to reduce the electric power consumption of PCs in active and inactive states. </li></ul><ul><li>Green Computing Impact Organization, (GCIO) is a non-profit organization dedicated to assisting the end-users of computing products in being environmentally responsible. </li></ul><ul><li>Green Electronics Council-- The Green Electronics Council offers the Electronic Products Environmental Assessment Tool (EPEAT) to assist in the purchase of &quot;green&quot; computing systems. </li></ul>
  13. 13. <ul><li>Approaches to green computing </li></ul><ul><li>Algorithmic efficiency: </li></ul><ul><li>The efficiency of algorithms has an impact on the amount of computer resources required for any given computing function and there are many efficiency trade-offs in writing programs. </li></ul><ul><li>Virtualization: </li></ul><ul><li>Computer virtualization refers to the abstraction of computer resources, such as the process of running two or more logical computer systems on one set of physical hardware. </li></ul>
  14. 14. <ul><li>Terminal Servers: </li></ul><ul><li>Terminal servers have also been used in green computing methods. When using terminal servers, users connect to a central server. </li></ul><ul><li>Power management: </li></ul><ul><li>In the power management ,we have to manage the Power supply, Storage, Video Card, Display and operating system issues. </li></ul>
  15. 15. <ul><li>Recycling </li></ul><ul><li>Recycling involves processing used materials into new products to prevent waste of potentially useful materials, reduce the consumption of fresh raw materials, reduce energy usage, reduce air pollution and water pollution. </li></ul><ul><li>Recycling is a key component of modern waste management and is the third component of the “Reduce ,Reuse, Recycle&quot; waste hierarchy. </li></ul><ul><li>Recyclable materials include many kinds of glass paper, metal, plastic textiles, and electronics. </li></ul>
  16. 16. The Recycle Logo OR
  17. 17. <ul><li>Concrete blocks </li></ul><ul><li>batteries </li></ul><ul><li>Steel recycling </li></ul><ul><li>Plastic </li></ul>
  18. 18. Computer recycling <ul><li>Computer recycling is the recycling or reuse of computers. </li></ul><ul><li>It includes both finding another use for materials (such as donation to charity), and for reuse in other products. </li></ul>
  19. 19. Reasons for recycling <ul><li>Many materials used in the construction of computer hardware can be recovered in the recycling process for use in future production. </li></ul><ul><li>Reuse of tin, silicon,iron,aluminium, and a variety of plastics— all present in bulk in computers — can reduce the costs of constructing new systems. </li></ul><ul><li>In addition, components frequently contain copper, gold, and other materials valuable enough to reclaim in their own right. </li></ul>
  20. 20. Recycling methods <ul><li>Consumer recycling : </li></ul><ul><li>Consumer recycling options include donating computers directly to organizations in need, sending devices directly back to their original manufacturers, or getting components to a convenient recycler. </li></ul>
  21. 21. <ul><li>Donation : </li></ul><ul><li>Consumer recycling includes a variety of donation options, such as charities which may offer tax benefits. The U.S.EPA maintains a list of donation options for American consumers. </li></ul><ul><li>Take back: </li></ul><ul><li>When researching computer companies before a computer purchase, consumers can also find out if they offer recycling services. Most major computer manufacturers offer some form of recycling. </li></ul><ul><li>Exchange </li></ul><ul><li>Manufacturers often offer a free replacement service when purchasing a new PC. Dell computers and Apple Inc.will take back old products when one buys a new one. Both refurbish and resell their own computers with a one-year warranty. </li></ul>
  22. 22. Corporate recycling <ul><li>Businesses seeking a cost-effective way to recycle large amounts of computer equipment responsibly face a more complicated process. </li></ul><ul><li>They also have the option of contacting the manufacturers and arranging recycling options. </li></ul>
  23. 23. Ergonomics <ul><li>Ergonomics is the science of designing the job, equipment, and workplace to fit the worker . </li></ul><ul><li>Ergonomics is employed to fulfill the two goals of health and productivity. It is relevant in the design of such things as safe furniture and easy-to-use interfaces to machines. </li></ul>Back
  24. 24. <ul><li>Telecommuting </li></ul><ul><li>Teleconferencing and Telepresence technologies are often implemented in green computing initiatives. </li></ul><ul><li>The advantages are many like, </li></ul><ul><li>Increased worker satisfaction, reduction of greenhouse gas emissions related to travel, and increased profit margins as a result of lower overhead costs for office space, heat, lighting. </li></ul>
  25. 25. Advantages of green computing <ul><li>The advantages of green computing are: </li></ul><ul><li>Reduce the use of hazardous materials. </li></ul><ul><li>Maximize energy efficiency during the product's lifetime. </li></ul><ul><li>Promote recyclability or biodegradability of defunct products and factory waste. </li></ul>
