Green Computing

  2. 2. What is Green Computing? The study and practice of designing, manufacturing, using and disposing of computers and associated subsystems such as monitors, printers, storage devices, networking and communication systems efficiently and effectively with no impact on the environment.
  3. 3. Consequences of Non-Green Computing Release of harmful gases from electronics More utilization of power and money Increase of E-waste and improper disposal
  4. 4. Annual Power Wastage and Cost Appliances Hours per Day Watts Annual when ON Cost of use Watts on Stand By Annual Cost on Stand By % Wasted TV 2 75 £7.12 14 £14.61 67% VCR 1 15 £0.07 8 £9.07 99% COMPUTER 2 60 £5.69 13 £13.57 70% MICRO WAVE 25 1700 £20.17 24 £27.05 57% BATTERY CHARGER 6 12 £3.41 10 £3.79 53% TOTAL COST £49.36 £104.5
  5. 5. Manufacturing of PCsHazards. Lead: Mercury: Cadmium: Used in soldering of printed circuit boards. Lead can cause damage to the central and peripheral nervous system , blood systems and kidneys. Used in batteries, switches . Mercury spreads out in water transforming into methylated mercury that can cause chronic brain damage. Used in resistors for chips and in semiconductors . Cadmium is classified as toxic, these compounds accumulate in the human body, particularly the kidneys.
  6. 6. Benefits of Green Computing Reduces the amount of pollutants in the surroundings. It saves the power consumption and reduces the amount of heat produced from the electronics. It reduces the burden on paper industry. Encourages the use of Renewable Resources. Promotes effective utilization of natural resources.
  7. 7. Green Manufacturing Bamboo : is becoming increasingly popular for making casings for computers and peripherals. Recyclable plastics : computers are constructed from non-recyclable plastics ie recyclable polycarbonate resin. Eco-friendly flame retardant : there are flame retardant silicone compounds available that are flame retardant and completely non-toxic. Inventory management : reducing the quantity of both hazardous materials used in the process and the amount of excess raw materials. Volume reduction : removes hazardous portion of waste from non hazardous portion.
  8. 8. Disposal of components Europe has outlawed using landfills for computer components Disposal of these devices constituted 20-50 million tons per year (about 5% of the total waste of the planet) this waste is called e-waste Toxic chemicals in electronics products can reach into the land over time or are released into the atmosphere, impacting nearby communities and the environment. This releases heavy metals such as lead, cadmium and mercury into the air and ashes.
  9. 9. 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 it new. Recycle: One of the major challenges is recycling the printed circuit boards from the electronic wastes. The circuit boards contain such precious metals as gold, silver, platinum, etc. and such base metals as copper, iron, aluminum.
  10. 10. Powering in an E-mail System Energy is consumed in three places when a user check their email • The Client: The PC, laptop, phone or other device directly accessing email is called the client. Its using electricity as it fetches and displays email. • The Network: Wireless routers, network switches and all the intervening networking equipment between the client and the email server use electricity. • The Server: The computer or group of computers receiving, sending and storing email is called email server. This machine and group of machines is constantly ON and consuming electricity.
  11. 11. Computer Housing and Cooling The energy email servers consume directly is only one component of the energy used to store and deliver email. Additional energy is required to house and cool the servers. Cloud providers take advantage of this efficiency in scale by providing servers for millions of users—maximizing the utilization of machines while cutting down on the total number of servers required. The result is fewer machines and less energy over all. Google has developed Gmail for Google Apps, a cloud-based email service used by over 4 million organizations, small and large. Gmail is constantly improving as we integrate new efficiency improvements, develop ways of streamlining our operations, and, of course, increase capabilities. Software developers, hardware designers and data center technicians have a unified goal of optimizing Google services to use as few resources as possible.
  12. 12. Research and Development IBM in 1990 saved around 4.6 billion kWh of electricity and prevented almost 3 million metric tones of CO2 emissions. Since 2007, Google has been a carbon neutral company, utilizing energy efficient improvements, green power and carbon offsets to bring our footprint down to zero. Users of Gmail also enjoy this benefit of zero carbon emission email. Choosing Gmail over a locally hosted server can mean an annual per-user power savings of up to 170 kWh and a carbon footprint reduction of up to 100 kg of CO2
  13. 13. How to go Green Turn off the computer when not in use, even if just for an hour Turn off the monitor when not in use Use power saver mode Use hardware/software with the Energy Star label Don’t print unless necessary and you are ready Use LCDs instead of CRTs as they are more power efficient Consider a smaller monitor-a 14-inch display uses 40% less energy than a 17-inch one. Enable Stand By/Sleep mode. Recycling Switching from a locally hosted email system to cloud based email
  14. 14. Energy Star One of the first manifestations of the green computing movement was the launch of energy star program back in 1992. Energy Star served as a kind of voluntary label awarded to computing products that succeeded in minimizing use of energy while maximizing efficiency. Energy Star applied to products like computer monitors, television sets and temperature control devices like refrigerators, air conditioners, and similar items.
  15. 15. How to save energy while working on the internet ? Blackle is a 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 Blackle claims having saved 3.12 MWh (megawatt hours) of electrical energy up to now (May 28th 2012)
  16. 16. How to save energy while working on the computer?   Sleep mode: Sleep or standby mode conserves energy by cutting off power to your display, hard drives and peripherals. After a pre-set period of inactivity, your computer switches to a low power state. Hibernate mode : Saves energy and protects your work by copying system data to a reserved area on your hard drive and then completely turning off your computer. Reduces wear and tear on your components.
