    • GREEN COMPUTING A new born child for an ECO friendly computing By M.Dawood Ameera
    • Introduction
      • Go Green
      • Causes
      • Approaches
      • Cloud and Green
      • Advantages
      • Disadvantages
      • Green Use
      • Green Disposal
      • Green Design
      • Green Manufacturing
    • Causes for Green Computing
      • Use lot of Electricity
      • Creates lots of toxic waste
      • Impact of Electricity to the Environment
      • Impact of Toxic waste to the Environment
    • EUP-Energy Usage Profile
      • CPU uses 120 Watts
      • CRT uses 150 Watts
        • 8 hours of usage, 5 days a week = 562 KWatts
          • if the computer is left on all the time without proper power saver modes, this can lead to 1,600 KWatts
      • Energy use comes from
        • electrical current to run the CPU, motherboard, memory
        • running the fan and spinning the disk(s)
        • monitor (CRTs consume more power than any other computer component)
        • printers
    • Toxicity
      • Metals like Lead, Mercury, Cadmium, Hexavalent Chromium, Plastics, tin, copper, carbon and aluminum
      • Iron, Silicon, Lithium, Zinc, Gold, Sulphur
    • E-Waste
      • Electronic waste (eWaste) is one of the most controllable pieces of the waste stream. Recycling eWaste is easy; recycling eWaste morally and ethically takes a bit more work.
      • What is electronic waste? Any cell phone, computer, monitor, printer, CD, battery, television or other business or consumer electronics device, including cables. When disposed off improperly, these materials contain elements that work their way into our water table. The elements are also rendered non-reusable as they are blended in with other waste and lost.
    • Approaches to Green Computing
      • Algorithmic Efficiency
      • Power Management
      • Video Card
      • Telecommuting
    • Algorithmic Efficiency
      • A study by a physicist at Harvard, estimated that the average Google search released 7 grams of carbon dioxide (CO₂)
      • More recently, an independent study by GreenIT.fr demonstrate that Windows 7 + Office 2010 require 70 times more memory (RAM) than Windows 98 + Office 2000 to write exactly the same text or send exactly the same e-mail than 10 years ago
    • Reducing Energy Consumption
      • Turn off the computer when not in use, even if just for an hour
      • Turn off the monitor when not in use (as opposed to running a screen saver)
      • Use power saver mode
        • in power saver mode, the top item is not necessary, but screen savers use as much electricity as any normal processing, and the screen saver is not necessary on a flat panel display
      • Use hardware/software with the Energy Star label
        • Energy Star is a “seal of approval” by the Energy Star organization of the government (the EPA)
      • Don’t print unless necessary and you are ready
      • Use LCDs instead of CRTs as they are more power efficient
    • Video Card
      • A fast GPU may be the largest power consumer in a computer.
      • Energy efficient display options include:
      • No video card - use a shared terminal, shared thin client, or desktop sharing software if display required.
      • Use motherboard video output - typically low 3D performance and low power.
      • Select a GPU based on low idle power, average wattage or performance per watt.
    • Telecommuting
      • Teleconferencing and Telepresence technologies are often implemented in green computing initiatives.
      • The advantages are many; 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, etc.
      • Voice over IP (VoIP) reduces the telephony wiring infrastructure by sharing the existing Ethernet copper. VoIP and phone extension mobility also made hot desking more practical.
    • ReFurbish
      • rather than discarding your computer when the next generation is released, just get a new CPU and memory chips – upgrade rather than replace
        • while you will still be discarded some components, you will retain most of the computer system (e.g., monitor, the system unit housing, cables)
    • ReCycle
      • Computer monitors (CRTs) contain an average of 4 lbs. of lead, a lot of reusable glass, chromium and mercury. All of these elements can be extracted and reused. For example, our recycler takes the glass from old monitors, and sends them to Samsung for use on flat screen monitors and TVs.
      • CDs/DVRs contain gold, glass, plastic, nickel and other elements that are completely recoverable and reusable.
      • Batteries – everything from the batteries that power your phone, laptop, and mouse can be recycled, whether single-use or rechargable.
    • ReUse
      • donate your computer components to people who may not have or have lesser quality computers
        • inner city schools, churches, libraries, third world countries
          • this however leads to the older computers being dumped but there is probably no way around this as eventually the older computers would be discarded anyway
    • Green Technologies
      • Power Saving by Link Status
      • Power Saving by Cable Length
      • Time-Based Power over Ethernet (PoE)
      • Wi-Fi Scheduler
      • SharePort
      • LCD Standby
      • Power Saving by Hard Drives Hibernation
      • Smart FAN
    • Green Web Surfing Greener Google Browsing: Blackle.com Being Green with Yahoo! Greener FireFox Surfing - Few other examples
      • Make sure the data center is using power generated by renewable energy sources or that it uses “free cooling” methods .
      • Look for modular data center approaches .
      • Get yourself more energy-efficient power and cooling systems . 
      • Think converged .
      • Virtualize and automate .
      • Measure and manage . 
      • Set goals and strive for them.
      CLOUD COMPUTING MAKING IT GREEN
    • Advantages
      • Both green computing and hardware disposal focus on being green to help have less of an impact on our enviroment.
      • Recycling like NewTech disassembles and reuses parts from old computers to build new, better ones, without just dumping them in a landfill.
    • DisAdvantages
      • Rapid technology change, low initial cost, and with planned obsolescence have resulted in a fast-growing surplus of unused hardware around the globe. Dave Kruch, CEO of Cash For Laptops, regards electronic waste as a “rapidly expanding” issue.
      • Technical solutions are available, but in most cases a legal framework, a collection system, logistics, and other services need to be implemented before a technical solution can be applied.
