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.

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.

A recent research, done by the research firm Gartner, claimed that IT causes 2 percent of global emissions nowadays..

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

GREEN COMPUTING

-THE FUTURE LIES AHEAD

04/10/2023

Why

o computer energy is often wasteful .$250 billion per year spent on powering computers

worldwide only about 15% of that power is spent computing- the rest is wasted idling.

o printing is often wasteful.

For a “paperless” society, we tend to use more paper today than before computer-prevalence.

GREEN COMPUTING

04/10/2023 4

Green computing:

The study and practice ofusing computing resourcesin an efficient, effectiveand economic way.

04/10/2023 5

Approaches to Green computing:

VirtualizationPower managementMaterial recycling

04/10/2023 6

VIRTUALIZATIONVIRTUALISATION IS THE PROCESS OF RUNNING TWO OR MORE LOGICAL COMPUTER SYSTEMS ON ONE SET OF HARDWARE , MINIMISING POWER AND COOLING CONSUMPTION.

04/10/2023

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.

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.

Revolutionized Data centers power efficiency.

Concept Of Virtualization:

04/10/2023

Power supply: Most computers drain more power than they

actually need during their operation. “80 plus” certification saves 85kwh per PC

per year. ACPI : Advanced configuration and power

interface Storage: Most conventional storage is the 3.5” Hard drive. Better power saving options for storage are : -Low RPM power saving model -solid state hard drive consumes 1/3rd power

consumed by 2.5” drive though its expensive.

Power management:

04/10/2023

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

•Reuse an older video card that uses little power many do not require heat sinks or fans

. •Select a GPU based on average wattage of performance per watt.

LCDS: 66% more efficient than the CRTS.

Consider that the average computer lifespan is about 2 years.◦ Between 1997 and 2004, it is estimated that 315

million computers became obsolete (and were discarded, donated, or recycled)

183 million computers were sold in 2004. New users in China (178 million by 2010) and India

(80 million by 2010) will require the creation of new computers

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.◦ where are we going to put all of it?

10

Concerns:The fills are filled

Reuse: donate your computer components to people who may not have or have lesser

quality computers.

Refurbish: rather than discarding your computer when the next generation is released, just get a new CPU and memory chips – upgrade rather than replace.

Are there adequate incentives to do either of the above? Do computer companies encourage refurbishing/upgrading?

04/10/2023 11

Solution to e-waste:

04/10/2023

If companies can recycle the plastics and other components, this can greatly reduce waste and toxins◦ however, the hazardous materials in e-waste can harm the

recycle workers if they are not properly protected

Developed countries now have facilities for recycling e-waste◦ however, in Europe, the plastics are discarded instead of

recycled because the flame retardant chemicals are too toxic to work with

To resolve these problems, the computer manufacturers must start using recyclable chemicals

12

ANOTHER SOLUTION:RECYCLING

04/10/2023

Develop a sustainable green computing plan.

Reduce-Re use-Recycle. Make environmentally sound purchase

decision. Reduce paper consumption. Use e-mails, electronic-archiving, track

changes in electronic documents. Conserve energy.

FIT PC : THE GREEN PC

Consume only 5W of power.

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.

17

04/10/2023

ZONBU COMPUTERS Energy efficient pc. Consumes one third of

power of typical light bulb.

Contains no moving parts.

It runs the Linux operating system.

Cost is only $99 with a two years subscription signed.

18

04/10/2023

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.19

You can help!

04/10/2023

consumers haven't cared about ecological impact when buying computers, they've cared only about speed and price.

Become pickier about being green.

The greenest computer will not miraculously fall from the sky one day; it’ll be the product of years of improvements.

The features of a green computer of tomorrow would be like: efficiency, manufacturing & materials, recyclability, service model, self-powering.

Green computers will break down the 'digital divide', the electronic gulf that separates the information rich from the information poor
