A Discussion on Green Computing

"Each PC in Use Generates  about a Ton of Carbon  dioxide Every year" 

We are passionate about advances in and widespread adoption of IT. However, IT has been contributing to environmental problems, which most people don’t realize.To reduce IT’s environmental problems and to create a sustainable environment, we call upon the IT sector as well as every computer user to green their IT systems, as well as the way they use these systems. We are legally, ethically, and socially required to green our IT products, applications, services, and practices.

Green IT is a hot topic today and will continue to be an important issue for several years to come.

Green : A Computer's Entire Life-cycle

Green IT

Green IT refers to environmentally sound IT. It’s the study and practice of designing, manu-facturing, using, and disposing of computers, servers, and associated subsystems—such as monitors, printers, storage devices, and net-working and communications systems—effi-ciently and effectively with minimal or no impact on the environment.

Greening data centers

The continued rise of Internet and Web ap-plications is driving the rapid growth of data centers. Enterprises are installing more serv-ers or expanding their capacity. The number of server computers in data centers has increased sixfold to 30 million in the last decade, and each server draws far more electricity than ear-lier models. Aggregate electricity use for servers doubled between 2000 and 2005, most of which came from 

businesses installing large numbers of new servers.

Greening Unwanted Computers: The Three R's

unwanted computers and monitors shouldn’t be thrown away in rubbish bins, as they will then end up in landfills causing serious environmental problems. instead, we should refurbish and reuse or recycle them in environmentally sound ways.

Research possible applications of green computing include:
  * Data center and overall energy efficiency
  * The disposal of electronic waste and recycling
  * Telecommuting
  * Virtualization of server resources
  * Thin client solutions
  * Use of open source software, and
  * Development of new software to address green computing for internal use and potential sales to other organizations.
