This document discusses green computing, which aims to reduce the environmental impact of computing devices through their design, use, and disposal. It provides a brief history of green computing beginning in 1992 with the US Energy Star program. The document then covers the needs for green computing due to electricity and toxic waste from manufacturing. Steps for green computing include using energy efficient hardware, reducing paper consumption, recycling e-waste, and following computer ethics. The advantages are reducing energy usage, CO2 emissions, and costs. The disadvantages include rapid technology changes and potentially underpowered green computers.

3. What Is Green Computing?
• Green computing is the study and practice
of environmental sustainable computing or IT.
• Designing, manufacturing, using and
disposing of computing devices in a way that
reduces their environmental impact.
• Important for all classes of systems, ranging
from handheld systems to large-scale data
centers.
• Many corporate IT departments have green
computing initiatives to reduce the
environmental effect of their IT operations.

4. HISTORY
• Started in the 1992 when US environment protection energy
launched the “Energy Star” Program.
• Energy star was a program of label awarded to computers and other
electronic devices. It was basically used to minimize the use of the
energy and maximize the efficiency of the product/device.
• This labeling program is basically designed to promote and
recognize the energy efficiency in monitors, climate control
equipment and other technologies

5. Need
The major causes for Green computing are:-
lot of electricity is used
Creates more toxic waste-:
(Due to toxic chemicals involved in the manufacturing)
Printing is often wasteful
Pollution
(due to manufacturing,packaging and disposal techniques)

6. Steps For Green Computing
 Energy efficient hardware
 Sustainable Green Computing Plan
 Reduce Paper Consumption
 E-Waste Recycling
 Telecommunication
 Use of Energy Star Labeled Products –
 Follow These Basic Computer Ethics-:
 Enable PC power management feature in your operating system.
 Turn off your computer when not in use.
 Screen saver doesn't save energy. So avoid screen saver and turn off your monitor.
 Use LED monitors overs LCD.
 Use sleep mode whenever you leave the PC on.
 Always use the 80-plus certified power supply units for your computer.

7. Advantages
 Reduces energy usage and controls CO2
 Uses less energy for electronic products during there
production, use and dispose.
 It saves energy and money too.
 includes environment policy to encourage recycling
and lowering energy use by individuals
and business.

8. Disadvantages
 Rapid technology change
 Some computers that are green may be considerably
underpowered
 High Startup cost
 Still in experinmental stages

9. Conclusion
 Thus Green computing aims to reduce the unwanted and
harmful effects of computers on the environment by
reducing air, water and soil pollution
 Though the challenges are many but with the ever
increasing research in the fields of science and
technology, we can overcome the hindrances
 Through the small steps that each one of us takes
towards adopting green computing measures, we can
make our environment pleasant for healthy growth
