 According to a research done by the Harvard University, a fullsearch requests done on the search engine Google, produce asmuch carbon dioxide as boiling a kettle of water. Every time youdo a search requests on Google, it produces 7 grams of CO2.,[object Object], In total there are 200 million search requests done on Google every day, that's1,400,000 kg of carbon dioxide every day. Google replied to this research by claiming that every search request would just produce 0,2 gram of carbon dioxide. And, if you do the math's , that's just 40,000 kg of carbon dioxide every day.,[object Object], A recent research, done by the research firm Gartner, claimed that IT causes 2 percent of global emissions nowadays..,[object Object], Previously, it has been calculated that worldwide 8.3 megawatt hours could be saved, if the home page of Google would be black instead of white,[object Object],9/25/2010,[object Object],1,[object Object],  AND HOW DO YOU REACT TO THAT!,[object Object]
NAME- AurobindoNayak,[object Object],REGD. NO-0701288307,[object Object],BRANCH- CSE,[object Object],9/25/2010,[object Object],2,[object Object],SEMINAR,[object Object]
GREEN COMPUTING,[object Object],-THE FUTURE LIES AHEAD,[object Object],9/25/2010,[object Object],2,[object Object]
Why,[object Object],[object Object], .$250 billion per year spent on powering computers                  worldwide only about 15% of that power is spent  computing- the rest is wasted idling.,[object Object],[object Object],   For a “paperless” society, we tend to use more paper today than before computer-prevalence.,[object Object], Global warming,[object Object],     .pollution ,[object Object],     .toxicity,[object Object],9/25/2010,[object Object],3,[object Object],        GREEN COMPUTING ,[object Object]
9/25/2010,[object Object],4,[object Object],Green computing:,[object Object],The study and practice of,[object Object],	using computing resources,[object Object],	in an efficient, effective,[object Object],	and economic way.,[object Object]
9/25/2010,[object Object],5,[object Object],Approaches to Green  computing:,[object Object],Virtualization,[object Object],Power management,[object Object],Material recycling,[object Object]
9/25/2010,[object Object],6,[object Object],VIRTUALIZATION,[object Object],VIRTUALISATION IS THE PROCESS OF RUNNING TWO OR MORE LOGICAL COMPUTER SYSTEMS ON ONE SET OF HARDWARE , MINIMISING POWER AND COOLING CONSUMPTION.,[object Object]
With virtualization, a system administrator could combine several physical systems into virtual machines on one single, powerful system, thereby unplugging the original hardware and reducing power and cooling consumption.,[object Object],Storage virtualization uses hardware and software to break the link between an application, application component, system service or whole stack of software and the storage subsystem.,[object Object],Revolutionized Data centers power efficiency.,[object Object],9/25/2010,[object Object],7,[object Object],Concept Of Virtualization:,[object Object]
[object Object],   Most computers drain more power than they  actually  need during their operation.,[object Object],   “80 plus”  certification  saves  85kwh  per  PC  per  year.,[object Object],ACPI : Advanced configuration and power interface,[object Object],[object Object],   Most conventional storage is the 3.5” Hard drive.,[object Object],   Better power saving options for storage are  :,[object Object],     -Low RPM power saving model,[object Object],     -solid state hard drive consumes 1/3rd      power           	consumed by 2.5” drive though its           	expensive.,[object Object],9/25/2010,[object Object],8,[object Object],Power management:,[object Object]
Video card:,[object Object],       A fast GPU may be the largest power consumer in a computer.,[object Object],Energy efficient display options include:,[object Object],      •No video card - use a  shared  terminal,  shared   thin   client, ,[object Object],        or desktop sharing software if display required.,[object Object], •Use motherboard video output ,[object Object], •Reuse  an  older  video  card  that  uses  little  power  many  do                         not require heat sinks or fans,[object Object],. •Select a GPU based on average wattage of performance  per watt.,[object Object],LCDS:,[object Object],        66% more efficient than the CRTS.,[object Object],9/25/2010,[object Object],9,[object Object],Displays:,[object Object]
Consider that the average computer lifespan is about 2 years.,[object Object],Between 1997 and 2004, it is estimated that 315 million computers became obsolete (and were discarded, donated, or recycled),[object Object],183 million computers were sold in 2004.,[object Object],New users in China (178 million by 2010) and India (80 million by 2010) will require the creation of new computers,[object Object],Disposal of these devices constituted 20-50 million tons per year (about 5% of the total waste of the planet),[object Object],This waste is called e-waste.,[object Object],where are we going to put all of it?,[object Object],9/25/2010,[object Object],Concerns:The fills are filled,[object Object],10,[object Object]
Reuse:  donate your computer components to ,[object Object],  people who may not have or have lesser quality computers.,[object Object],Refurbish: rather than discarding your computer when the next generation is released, just get a new CPU and memory chips – upgrade rather than replace.,[object Object],Are there adequate incentives to do either of the above?  Do computer companies encourage refurbishing/upgrading?,[object Object],9/25/2010,[object Object],11,[object Object], Solution to e-waste:,[object Object]
If companies can recycle the plastics and other components, this can greatly reduce waste and toxins,[object Object],however, the hazardous materials in e-waste can harm the recycle workers if they are not properly protected,[object Object],Developed countries now have facilities for recycling e-waste,[object Object],however, in Europe, the plastics are discarded instead of recycled because the flame retardant chemicals are too toxic to work with,[object Object],To resolve these problems, the computer manufacturers must start using recyclable chemicals,[object Object],9/25/2010,[object Object],12,[object Object],ANOTHER SOLUTION:RECYCLING,[object Object]
Develop a sustainable green computing plan.,[object Object],Reduce-Re use-Recycle.,[object Object],Make environmentally sound purchase decision.,[object Object], Reduce paper consumption.  ,[object Object],Use e-mails, electronic-archiving, track      changes in electronic documents.,[object Object],Conserve energy.,[object Object],9/25/2010,[object Object],13,[object Object],GO GREEN : THE BASIC 5 STEPS,[object Object]
9/25/2010,[object Object],14,[object Object],PLANNING GREEN IT,[object Object]
APPLICATIONS  OF			     GREEN COMPUTING:		,[object Object],9/25/2010,[object Object],16,[object Object]
9/25/2010,[object Object],16,[object Object],Blackle.eu:THE ECO-FRIENDLY SEARCH  MACHINE,[object Object]
FIT PC : THE  GREEN  PC,[object Object],[object Object]
Thin as a paperback and absolutely silent
Consumes less power for a day than a traditional consumes in an hour.
Compact, quite and green, perfect fit for 24/7 use.9/25/2010,[object Object],17,[object Object]
ZONBU COMPUTERS,[object Object],Energy efficient pc.,[object Object],Consumes one third of power of typical light bulb.,[object Object],Contains no moving parts.,[object Object],It runs the Linux operating system.,[object Object],Cost is only $99 with a two years subscription signed.,[object Object],9/25/2010,[object Object],18,[object Object]
Turn off the computer when not in use, even if just for an hour,[object Object],Turn off the monitor when not in use (as opposed to running a screen saver),[object Object],Use power saver mode ,[object Object],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,[object Object],Use hardware/software with the Energy Star label                  ,[object Object],Energy Star is a “seal of approval” by the Energy Star organization of,[object Object],    the government (the EPA),[object Object],Don’t print unless necessary and you are ready,[object Object],Use LCDs instead of CRTs as they are more power efficient.,[object Object],9/25/2010,[object Object],19,[object Object], You can help!,[object Object]
