CONTENT

• Introduction• Origin• Approaches • Implement• Simple Tasks• Advantages & Disadvantages• CONCLUSION

Green computinG is the study and practice of using computing resources efficiently.

Green computinG or Green IT goals are similar to green chemistry.

WHY GO GREEN?

Computer energy is often wasteful

Pollution

Origin• In 1992, the U.S. Environmental Protection

Agency launched Energy Star, a voluntary labelling program which is designed to promote and recognize energy-efficiency in monitors, climate control equipment, and other technologies.

• Saved $14 billion in energy costs in 2006 alone.

• Widespread adoption of sleep mode

• EPEAT, is focused on promoting energy efficient products.

Virtualization

Power management

IT equipment recycling

Remote conferencing & Telecommuting strategies

Approaches to Green Computing

Display:

•LCD displays: use a CCF bulb

•LED displays: use an array of LEDs

•LCD monitors uses 3 times less when active, and 10 times less energy when in sleep mode.

•LCDs are up to 66% more energy efficient.

•LCDs are also smaller in size and weight.

•21" CRT typically uses more than 120W.

Approaches to Green Computing

Operating System Support :•Windows 7 includes refinements for more efficient user of operating system timers, processor power management, and display panel brightness.

•Linux Os utilizing less resources than other OS, and also have a better power management facility.

Terminal servers:•Terminals can be combined with thin clients, which use up to 1/8 the amount of energy of a normal workstation.

Remove unused equipment and software

Power-sucking displays can be replaced

with OLEDs.

Use Linux, which requires less resources

than many other OS.

BLACKLE• Search-engine site

powered by Google Search.

• White consumes 74W whereas black it consumes only 59W.

• Different colors consumes different amounts of energy.

ZONBU COMPUTER

•New and energy efficient PC.

•Runs the Linux OS using 1.2GH processor & 512MH of RAM.

•Consumes one third of the power of a typical light bulb.

•Size of a paperback and

silent, run WindowsXP or

Linux.

•Draws only 5 Watts than PC.

FIT-PC

SUNRAY THIN CLIENT

•Consume less electricity than

conventional desktops.

•consumes 4 to 8 watts of power.

•The Asus Eee PC is one example of

an ultraportable.

•Factors of ultraportable combine to

enable them to run more efficiently

and use less power than a standard

Form factor laptop.

ASUS EEE PC

Simple Tasks for Go Green

• Buy and use a low power desktop or a laptop computer (40-90 watts) rather a higher power desktop (e.g. 300 watts).

• Thin clients can use only 4 to 8 watts of power at the desktop as the processing is done by a server.

• Buy hardware from manufacturers that have a hardware recycling scheme, and recycle your old computer equipment rather than sending it to landfill.

Steps by Apple• MacBook keyboards are made from one single

piece of aluminum

• MacBook pro notebooks have long lasting batteries where as a normal notebook uses three batteries a MacBook will only use one through out its life time.

Steps by DELL• Their free world-wide product recycling

program allows user to properly dispose their product safely.

• Their “Plant a tree for me” project can offset a customers carbon emissions for only three dollars.

ADVANTAGES &DISADVANTAGES

Advantage: By conserving resources Reduced usage of energy

Disadvantage: Costly

CONCLUSION

• The features of a green computer of tomorrow

would be like: efficiency, manufacturing &

materials, recyclability, service model, self-

powering, and other trends.

• The greenest computer will not miraculously fall

from the sky one day.
