• WHAT IS GREEN COMPUTING?

Green computing is the study and practice of

environmentally sustainable computing..i.e..

using computer resources efficiently.

• It includes the implementation of energy

efficient CPUs ,servers and other peripherals

as well as reduced resource consumption and

proper disposal of e-waste.

• It can include :

designing

manufacturing

using and disposing

computers , servers and other associated

subsystems efficiently and effectively with

minimal or no impact on environment.

• The term “GREEN COMPUTING ” came into existence after the “ENERGY STAR PROGRAMME” was launched by the US Environmental Protection Agency in 1992.

• It was a labeling programme that was designed to promote and recognize energy efficiency in monitors, climate control equipments and other technologies.

• Green computing focuses on the triple bottom line of economic viability, social responsibility and environmental impact.

• The three main goals are:

1. Reduce the use of hazardous materials.

2. Maximize the energy efficiency.

3. Promote the recyclability, biodegradability of defunct products and factory waste.

STRATEGIES

Minimizing power consumption by providing desired quality of service..

Put system into sleep mode in idle state.

• Less use of hazardous materials.

• Energy efficient.

• Recyclable materials used for manufacturing.

• End of life recovery

• Use of renewable and bio-based materials.

• Longer product retrieval.

• End of life take-back facility.

• Manufacturer’s certificate.

• Packaging material.

• EPEAT ratings.

• An average desktop computer and monitor consumes 60 to 300 watts of electricity which is why energy consumption and cost reduction programs represent a major area of focus and opportunity with green IT.

• A business with a network of 20,000 desktop systems running 24X7 drawing 200 watts consumes about 300 million kWh of electricity annually.

• Manufacturing computers include the use of lead,

cadmium, mercury and other toxics in general.

• According to green experts, computers can

contain 4 to 8 pounds of lead alone.

• Computers and other electronics made up two

fifth of all lead in landfills.

Data centers are the main reason behind energy consumption.

• According to Mark Bramfitt, principal program manager at PG&E.

“Data center servers use 50 times the energy per square foot as an office does”

• To keep servers at the right temperature, companies mainly rely on air conditioning equipments which leads to even more power consumption.

• Develop sustainable green computing plans.

• Recycle and reuse.

• Purchase products which are environmentally

green and sound.

• Minimizing consumption of paper.

• Conservation of energy

• Green procurement and asset management.

• Technology based solutions.

• Google is building a data center on Oregon’s Columbia River to tap hydroelectric power.

• Microsoft is building its data center nearby in Washington for the same reason.

• Financial services company HSBC is building a data center near Niagara Falls.

• Some of the best technology makers are going green. They are making green computers and computer based products which are readily available and they even provide buy back programs to help you dispose off your unwanted computers, peripherals and other electronic devices.

These companies are the ones we all know and trust:

• HEWLETT PACKARD :

1. In recent years, Hewlett Packard has introduced many Energy Star qualified computers onto the market, including several that have won high EPEAT ratings. For example, the HP Elite Book 2530p notebook computer is Energy Star 5.0 qualified and has earned EPEAT gold.

2. HP is striving to use more recycled materials in its products and product packaging.

3. HP has also instituted buy back and recycling programs for all brands of computers, monitors, printers, scanners and other computer technology.

• DELL:

1. Dell has introduced an ultra-green desktop computer called the Studio Hybrid. It is the greenest desktop computer up to date, the Studio Hybrid is Energy Star 5.0 qualified, has an 87% efficient power supply and an EPEAT gold rating.

2. The Dell Studio Hybrid can be customized with interchangeable sleeves; there's even a sleeve available that's made from renewable bamboo.

3. Dell has increased its investment in renewable energy from wind, solar and natural gas capture and has also made significant efforts to reduce its greenhouse gas emissions.

• APPLE:

1. Apple has begun to make many of its green computers

with recyclable materials such as aluminum,

polycarbonate and glass.

2. Apple has made efforts to remove toxic substances, such as

Brominated Fire Retardants (BFRs), Polyvinyl Chloride

(PVC), arsenic, lead and mercury from its products. Since

2008, the Apple Mac Book Pro has been free from each of

these dangerous environmental pollutants. By 2009, all

Mac notebook and desktop computers had earned an

EPEAT gold rating.

• LENOVO:

1. Lenovo uses post-consumer recycled materials such as plastic water bottles in the manufacture of its green computers.

2. All Lenovo ThinkPad laptop computers contain 85% recyclable materials and have achieved an EPEAT rating of either silver or gold.

3. Through its Eco Take Back program, Lenovo offers free recycling of all of its computers and other electronic products for small businesses and consumers in countries throughout the America, Asia and Europe.

• Turn off your computer when they are not in use as turning off or on will not harm the computer.

• Look for ways to reduce the amount of time your computer is on without adversely affecting your productivity.

• While using the laser printers ,don’t turn your printer on until you are ready to print.

• Unless you require immediate access to E-mails or other internet services, break the habit of turning on all your computer equipments all day.

• Some other green computing practices include:

Reducing paper waste:

Print as little as possible.

Recycle waste paper as many times as you can.

Save E-mail whenever possible and avoid needless printing of email messages.

Use e-mails instead of faxes to eliminate the number of hard copy.

While printing documents use the multiple pages per sheet option on printer properties.

Reusing and recycling of Hardware devices:

E-waste management

Making of unused and old hardware devices or computing resources reusable through recycling.

for example-

inkjet cartridges, batteries and diskettes can be recycled for further use.

Purchasing Recommendations:

Buy only Energy Star computers, monitors and printers. Flat panel monitors use about half of the electricity of a CRT (Cathode-Ray-Tube) display.

Buy inkjet printers, not Laser printers. These use 80%-90% less energy than laser printers and print quality can be excellent.

Buy non-petroleum based ink. These printer inks are made from renewable resources, require fewer hazardous solvents, which translate to fewer air emissions, and in many cases produce brighter, cleaner colors.

Buy a monitor only as larger as you really need. A 17-inch CRT monitor uses 30% more energy than a 15-inch one when each is in an active mode.

• Reduced energy usage from green computing techniques translates into lower carbon dioxide emission.

• Saving energy and resources saves money.

• Reduce the risk existing in the laptops such as chemical known to cause cancer, nerve damage and immune reactions in humans.

• Conserving resources means less energy is required to produce, use, and dispose of products.

• Green computing could actually be quite costly.

• Some computers that are green may be

considerably underpowered.

• The use of eco-friendly sustainable components

will become the norm rather than the exception in

future.

• Energy saved on computer hardware and

computing will equate tonnes of carbon emissions

saved per year.

It is clear that the mushrooming growth of IT

industries worldwide is slowly poisoning the

environment. This grave threat requires

immediate attention. Societies need to become

more energy conscious. The need of the hour is for

both governments and the corporate world to join

hands to usher in more green computing solutions

to be able to build a green-globe.
