Standardization of Green

ICT with Green

Communication

Outline

Present Statistics

• Power Consumption in ICT=2%
• 54 of the total import is Petroleum causing

environmental degradation and foreign

exchange drain

• Obsolesce in ICT - E-Waste

What is Green ICT

• The study and practice of designing, manufacturing,

using, and disposing of computers, servers, and

associated subsystems—such as monitors, printers,

storage devices, and networking and communications

systems—efficiently and effectively with minimal or no

impact on the environment.

• In the article Harnessing Green IT: Principles and

Practices, San Murugesan defines the field of green

computing as “The study and practice of designing,

manufacturing, using, and disposing of computers,

servers, and associated subsystems—such as monitors,

printers, storage devices, and networking and

communications systems—efficiently and effectively

with minimal or no impact on the environment.

Necessity of Green ICT

Lack of Classical Energy

It is well established that

• Tropical countries with
  • poor connectivity,
  • poor availability of energy
  • poor quality of electricity.
• And Greater availability of Green Resources
  • Solar energy
  • Wind energy
  • Geothermal energy
  • Bio mass
  • & poor standardization

Due to Impacting Environment

• Emissions to air
• Releases to water
• Releases to land
• Use of toxic materials in equipment
• Use of resources to produce Energy
• Energy emitted from use of Products
• Waste and by-products …. etc etc

• Green technologies will help move the declining use of fossil fuels.
• Better for the environment al protection. - Solar, wind, tide, geothermal, bio gas etc. (LOCATION SPECIFIC) - Sustainable in the long term. - Produce new jobs. Resource of Green Technology

"Green ICT" fall into one of two broad categories.

• Those intended to deal with global warming by either reducing greenhouse gas emissions or in the alternative its potential harmful effects on the planet.
• Those technologies associated with establishing economic "sustainable growth" which includes recycling, resource reduction and many aspects of the biosciences How are Green ICT used today?

Green ICT Deliverables As next step, working on:  Paper less Office  Energy Audit  Reduce In plain language, Green ICT is working out means of how IT can help ‘Save our Planet’ from environmental issues. Green ICT -

• Is not a product
• It is not a one time effort

As Photovoltaic Mobile and Laptop Recharger

Technology

• It works on principle of solar energy is converted into electrical energy
• Photovoltaic solar panels are composed mainly of silicon. Silicon is used because it naturally releases electrons (electrical energy) when hit with a photon (light source).
• photovoltaic solar panel consist of a clear protective top layer, two layers of specially treated silicon with collecting circuitry attached to the top layer , and a tough polymer backing layer.
• These two layers are separated by an electrically charged junction, which allows electrons to flow from back to front
• When light strikes the PV panel, some of the photons are absorbed by the silicon layers. The photons cause electrons to be released from the silicon crystal.
