IntroductionWhat is Green-IT?
Green computing or green IT, refers to environmentally sustainable computing.
Definition :
The study and practice of designing, manufacturing, using, and disposing of
computers, servers, and associated subsystemssuch as monitors, printers,
storage devices, and networking and communications systemsefficiently and
effectively with minimal or no impact on the environment."

Origins
In 1992, the U.S. Environmental Protection Agencylaunched Energy Star.
It is a voluntary labeling program designed to promote andrecognize energy-efficiency in monitors, climate control.
The term "green computing" was probably coined shortly
after the Energy Star program began.

Regulations and IndustryInitiatives
The Organization for Economic Co-operation and Development (OECD)has published a survey of over 90 government and industry initiatives on
"Green ICTs", i.e. information and communication technologies.
Some efforts place responsibility on the manufacturer to dispose of theequipment themselves after it is no longer needed; this is called theextended producer responsibility model.
Climate Savers Computing Initiative (CSCI) is an effort to reduce theelectric power consumption of PCs in active and inactive states.

Power Management The Advanced Configuration and Power Interface (ACPI), an open
industry standard, allows an operating system to directly control the
power-saving aspects of its underlying hardware.

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 hardware/software with the Energy Star label
Energy Star is a seal of approval by the Energy Star organization of the
government
Dont print unless necessary and you are ready
Use LCDs instead of CRTs as they are more power efficient

Disposal Consider that the average computer lifespan is about 2 years
10 years ago, the lifespan of a computer was 5 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 (674 million cell phones!)
New users in China (178 million by 2010) and India (80 million by 2010) willrequire the creation of new computers
Disposal of these devices constituted 20-50 million tons per year (about 5% ofthe total waste of the planet)
this waste is called e-waste where are we going to put all of it?

Other Solutions Re-use: 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 bediscarded anyway
Refurbish: rather than discarding your computer when the next generation isreleased, 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)
Do computer companies encourage refurbishing/upgrading?

Recycling Computer systems that have outlived their particular function can be
re-purposed, or donated to various charities and non-profit organizations.
Additionally, parts from outdated systems may be salvaged and recycled through
certain retail outlets and municipal or private recycling centers.
Before recycling a computer, users should remove the hard drive, or hard drivesif there is more than one, and physically destroy it or store it somewhere safe.

ConclusionGreen computing is a novel and an innovative trend inthe world of computing which has minimum or no impact
on the environment.
Green computing has introduced a range of equipmentsand technologies which help in limiting the impact on theenvironment.
