Green computing

  1. 1. By: Parth Patel Enr. No.: 11011010047 Branch: Computer Guided By: Mrs. Maulika Patel
  2. 2. INTRODUCTION  What is GREEN Computing???  What is the need for GREEN Computing???  How government is helping in GREEN Computing???  How to go GREEN???  Approaches to GREEN Computing.
  3. 3. WHAT IS GREEN COMPUTING??  According to the definition by San Murugesan; Green computing is the study and practice of designing, manufacturing, using and disposing all the computers, servers and associated subsystems efficiently and effectively with minimal or no impact on environment.  Manufacture ecofriendly devices/machines.  The technology which is beneficial to the environment.
  4. 4. NEED FOR GREEN COMPUTING??? At an average a typical computer use a 60-500 watts  Additional 35-150 watts with LCD or CRT screen. 500 +150 ------650 watts  Total Personal computer(400 million) energy usage in 2000=23 nuclear power plant.  Power is the main factor for improving the performance. 
  5. 5. POWER CONSUMPTION BY PROCESSORS oAs new and new processors are invented rate of power consumption increases. oAnd this high power consumption is not eco friendly.
  6. 6. POWER CONSUMPTION OF PROCESSORS Power Density (W/cm2) 1000 Nuclear Reactor 100 Pentium 4 Hot Plate 10 Pentium 3 Pentium 2 Pentium Pro Pentium 1 1980 386 486 1990 2000 2010
  7. 7. MORE REASONS FOR HIGH POWER CONSUMPTION.  As circuit speed increases, power consumption increases.  Designing low power circuits has been the most important issue.  Mobile devices demand long battery life.  Low power consumption is listed as the second greatest challenge for industry.
  8. 8. POWER CONSUMPTION AND DATA CENTER Where are the web page you browse??  Data center  One single room in data center contain 100 Racks.  1 Rack=5 to 20 kW  Contributed to the 2000/2001 energy crisis in California.  Client Internet Data Center Racks
  9. 9. ENVIRONMENTAL IMPACT Sun Datacenter •2006 •10.5M kWh •10K tons of Co2 WW Datacenter •2006 •209 kWh •200M tons of Co2 200M tons of Co2 Co2 produced by 40 million cars
  10. 10. COOLING DATA CENTER  o o Current Coolants: CFCs and HCFCs = OZONE DEPLETION Other coolants like HFC increase green house emission by 1300 times. As all this are creating global worming. MICROSOFT • Cold Siberia Sun • Underground
  11. 11. EFFECT OF GLOBAL WARMING. Effect of Global warming on Siberia Effect on Underground Japan
  12. 12. A SUPER LOW POWER PROCESSOR
  13. 13. AN AVERAGE ENERGY USAGE OF DATA CENTER $15 Billion for energy usage Impact of 10% Reduction of Power Consumption $15b $1.5 Billion in Saving 10% 200 10% 20 Million ton of Co2
  14. 14. CONCLUSION From the all above discussion we have seen that there is high power consumption by all this data centers, computers and other technical equipments.  To reduce the power consumption and make this all equipments echofriendly GREEN Computing is necessary. o
  15. 15. ROLE OF GOVERNMENT  Many government agencies have implemented standards and regulations to encourage GREEN Computing.  State-wide recycling programs for obsolete of computers and consumer electronic equipments.  Government provide fund to improve the energy efficiency of data centers.  Made e-waste collection centers.
  16. 16.  In 1992 the U.S Environmental Protection Agency launched Energy star, a voluntary labeling program that is designed to promote and recognize energy efficiency in monitors, climate control equipments and other technologies.
  17. 17. APPROACHES TO GREEN COMPUTING. Algorithmic Efficiency  Power Management  Video card  Display  Material Recycling  Telecommuting  e-waste Management  Make low power using machines 
