WHAT IS GREEN COMPUTING??
"The study and practice of designing,
manufacturing, using, and disposing
of computers, servers, and associated
subsystems efficiently and with no
impact on the environment."
Why Green Computing?
Computer energy saving.
Reduce wastage of printing.
Reasons for Adopting Green Solution
MANUFACTURING OF PC’S
Lead : used in soldering of printed
circuit boards lead can cause damage
to the central and peripheral nervous
system , blood systems and kidneys.
Mercury : used in batteries, switches .
Mercury spreads out in water transforming into
methylated mercury that can cause chronic brain
Cadmium : used in resistors for chips and in
semiconductors . Cadmium is classified as toxic
these compounds accumulate in the human
body, particularly the kidneys.
Energy Use of PCs
CPU uses 120 Watts
CRT uses 150 Watts
8 hours of usage, 5 days a week = 562 K watts
for a large institution, say a university of 40,000
students and faculty, the power bill for just
computers can come to $2 million / year
Energy use comes from
electrical current to run the CPU, motherboard,
running the fan and spinning the disk(s)
monitor (CRTs consume more power than any
other computer component)
One of the first manifestations of the green computing movement was the
launch of energy star program back in 1992.
Energy Star served as a kind of voluntary label awarded to computing
products that succeeded in minimizing use of energy while maximizing
Energy Star applied to products like computer monitors, television sets and
temperature control devices like refrigerators, air conditioners, and similar
Turn off the computer when not in use, even if just
for an hour
Turn off the monitor when not in use
Use power saver mode
Use hardware/software with the Energy Star label
Don’t print unless necessary and you are ready
Use LCDs instead of CRTs as they are more power efficient
Green Components manufacturing
Bamboo : It is becoming increasingly popular
for making casings for computers and
Recyclable plastics : computers are
constructed from non-recyclable plastics i.e.
recyclable polycarbonate resin.
Eco-friendly flame retardant : There are flame
retardant silicone compounds available that are flame
retardant and completely non-toxic.
Inventory management : Reducing the quantity of
both hazardous materials used in the process and the
amount of excess raw materials.
Volume reduction : Removes hazardous portion of
waste from non hazardous portion.

Methods Of Green Computing
DISPOSAL OF COMPONENTS
Europe has outlawed using landfills for
Disposal of these devices constituted 2050 million tons per year (about 5% of the
total waste of the planet)
This waste is called e-waste
Toxic chemicals in electronics products can
reach into the land over time or are released
into the atmosphere, impacting nearby
communities and the environment.
This releases heavy metals such as
lead, cadmium and mercury into the air and
Reuse: Donate your computer components to people who
may not have or have lesser quality computers.
Refurbish: Rather than discarding your computer upgrade
it. Change its some of the parts in order to make it new.
Recycle: One of the major challenges is recycling the printed
circuit boards from the electronic wastes. The circuit boards
contain such precious metals as gold, silver, platinum, etc. and
such base metals as copper, iron, aluminum.
Steps For Green Computing
Environmentally Sound Purchase
Sustainable Green Computing Plan
Reduce Paper Consumption
Change your subscriptions to online-not paper.
Optimize computer performance.
Decrease screen brightness.
Change from XP to Window 7.
Consider LCDs over CRTs.
Consider laptops over desktops.
Have a energy efficient approach.
Reduce Energy Usage
Reduces The Risk
Saving The Energy
Saving The Planet
FUTURE OF GREEN COMPUTING
The plan towards green IT should include new
electronic products and services with optimum
efficiency and all possible options towards
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, and other trends.
