Green computing is the environmentally responsible and eco-friendly use of computers and their resources. In broader terms, it is also defined as the study of designing, engineering, manufacturing, using and disposing of computing devices in a way that reduces their environmental impact. Many IT manufacturers and vendors are continuously investing in designing energy-efficient computing devices, reducing the use of dangerous materials and encouraging the recyclability of digital devices. Green computing practices came into prominence in 1992, when the Environmental Protection Agency (EPA) launched the Energy Star program.

2. What is Green Computing?
Green computing is the environmentally responsible and eco-
friendly use of computers and their resources. extensively, it is
also defined as the study of designing, engineering,
manufacturing, using and disposing of computing devices in a
way that reduces their environmental impact.
• It is used to denote efficient use of Resources in Computing
• It is also known as Green IT
• It is study and practice of designing, manufacturing, using and
disposing of computers ,servers and associated subsystems

3. Why Green Computing?
• Computer consumes a lot of energy.
• Printing often unnecessary stuff is waste
• Reduce pollution.
• Reduce the power consumption
• reduce the global warming
• Toxicity.

4. History
• It originated in 1992 at the U.S Environmental
Protection Agency that launched Energy Star
program.
• Shortly after that the term “Green Computing” was
coined.
• Shortly after that the Sweden also launched the TCO
Certification.

5. Path to Green Computing
• Green Use
• Green Disposal
• Green Design
• Green Manufacturing

6. Energy Consumption
 CPU uses 120 Watts
 CRT uses 150 Watts
Energy use comes from electrical current to run the
CPU, motherboard, memory
• running the fan and spinning the disk(s)
• monitor (CRTs consume more power than any other
computer component)
• printers

7. Approaches
• Product Longevity
• Software & deployment optimization
• Power management
• Materials Recycling
• Virtualization
• Algorithm Efficiency
• Power Supply
• Display
• Storage
• Telecommunicating

8. Methods to implement Green Computing
• Carbon Free Computing
• Solar Computing
• ROHS Computing(Restriction of Hazardous Substances)
• Virtualization

9. Reducing the 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 power saver mode
• Use LCDs instead of CRTs as they are more power
efficient
• Use hardware/software with the Energy Star label
• Choose Intel & VIA Processors in comparison to AMD
Processors

10. Steps For Green Computing
• Environmentally Sound Purchase Systems
• Sustainable Green Computing Plan
• Reduce Paper Consumption
• Conserve Energy
• Recycling

11. ADVANTAGES
• Energy saving
• Environmentally Friendly
• Cost-effective ( pays over time )
• Save more money per year
• Can give you a tax right off

12. DISADVANTAGES
• High start up cost
• Not readily available
• Still in experimental stages
• Sacrifice performance for battery life
• Not for everyone

13. Future of Green Computing
The plan towards green Computing should include new
electronic products and services with optimum
efficiency and all possible options towards energy
savings. That is enterprise wise companies are laying
emphasis on moving towards Eco Friendly
Components in Computers, the use of eco-friendly
sustainable components will become the norm
rather than the exception in future.

14. CONCLUSION
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.
