Every time we burn fossil
fuels such as gas, coal or oil,
carbon dioxide is released
into the atmosphere. In a
natural carbon cycle, carbon
dioxide is re-absorbed by
plants and trees.

Carbon Emission (CO2)

Carbon Footprints
the amount of carbon dioxide and other
carbon compounds emitted due to the
consumption of fossil fuels by a particular
person, group, etc.

Computing and CO2
How are computers related to Carbon Emission?
Every time you power up your computer, you’re drawing electricity
from the nearest power plant which is probably powered by coal,
oil, or natural gas.
And burning fossil fuels produces carbon dioxide.

Green Computing
“the study and practice of designing,
manufacturing, using, and disposing of
computers, servers, and associated
subsystems efficiently and effectively with
minimal or no impact on the environment.”
definition from google.com

Need for Green Computing
Energy Leaving computers on when not in use
Printing
Unnecessary printing of email, agendas, partial
drafts, etc.
Pollution
Manufacturing techniques, packaging, and
disposal
Toxicity Use of chemicals like mercury, lead, and cadmium

Laptop uses between 50
and 100 W/hour
Complete Desktop uses an
average of
200W/hour
Energy Consumption
Based on 8 hours usage a day
Annual consumption:
600 kWh
emissions of about 175 kg per
year
Annual consumption:
between 150 and 300 kWh
emissions between 44 and
88 kg per yearCO2 CO2
 
On stand-by, the power consumption of both a desktop and a laptop computer falls to about a third.
Every single computer requires about 1.8 tonnes of chemicals, fossil fuels and water for its manufacture.

In 1992, the U.S.
Environmental Protection
Agency launched Energy Star,
a voluntary labeling program
which is designed to promote
and recognize energy-
efficiency in monitors, climate
control equipment, and other
technologies.
The term "green computing" may be created
immediately after the Energy Star program
began.
The revised Energy Star
Specifications of 2007 place
stringent requirements to
attain energy star ratings.
In 2012, American household and businesses saved
$24 Billion on utility bills
Prevented greenhouse gas
emission equivalent to that
of 41 million vehicles.
History of Green Computing

13. devangdoshi.com
Energy Conservation
• Buy "Energy Star" labeled monitors, desktops, laptops,
and printers
• Turn off computers and peripherals when not in use
• Put monitor in sleep mode or turn it off instead of
using a screensaver
• Activate the power management feature on your
computer system
• Reuse, Refurbish, or E-cycle used equipment

14. devangdoshi.com
Green Manufacturing
• Bamboo is becoming increasingly popular for making
casings for computers and peripherals
• Use of recyclable plastics instead of non-recyclable
plastics
• Use of eco-friendly and non-toxic flame retardant
compounds
• Inventory Management: Process of reducing the
quality of both, hazardous material and raw material
• Volume Reduction: Removing of hazardous portion of
waste from non hazardous portion
