Green computing:


Is the environmentally responsible and eco-friendly use of computers, electronics and their resources. In broader terms, it is also defined as the study of designing, manufacturing/engineering, using and disposing of computing devices in a way that reduces their enviromental impact.


Green Computing is also known as green information technology (Green IT).



Explaining Green Computing:


Green Computing aims to attain economic viability and improve the way

compitung devices are used. Green IT practices the include of the development

of enviromentally sustainable production, energy efficient computers, electronics

and improved disposal and recycling procedures.


To promote green computing concepts at all possible levels, the following approaches are employed:


  • Green use: Minimizing the electricity consumption of computers and their peripheral devices and using them in an eco-friendly manner.


  • Green disposal: Re-purposing an existing computer or appropriately disposing of, or recycling unwanted electronic equipment.


  • Green design: Designing energy-efficient computers, servers, printers, projectors, HD TV's and other digital devices.


  • Green manufacturing: Minimizing waste during the manufacturing of computers and other subsystems to reduces the environmental impact of these activities.  


Advantages and disadvantages:

Advantages : 


      •  Reduced energy usage from green computing techniques translates into                  lower carbon dioxide emissions, stemming from a reduction in the fossil fuel            used in power plants and transportation. 

      •  Conserving resources means less energy is required to produce, use, and              dispose of products. 

      •  Saving energy and resources saves money. 

      •  Green computing even includes changing government policy to encourage              recycling and lowering energy use by individuals and businesses. 

      •  Reduce the risk existing in the laptops such as chemical known to cause                  cancer, nerve damage and immune reactions in humans. 


Disadvantages : 

       •  Green computing could actually be quite costly. 

       •  Some computers that are green may be considerably underpowered. 

       •  Rapid technology change
