  Overview of GreenComputing  “ Greening” your computing equipment is a low-risk way for your business.  It not only help the environment but also reduce costs.  It is one of the largest growing trends in business today.  Making a proper decision to go green not only improves the net profit of your business, but also reduces your carbon footprint.

  What is GreenComputing ? 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, manufacturing, using and disposing of computing devices in a way that reduces their environmental impact.”

  History:  The term“ Green Computing" was probably coined shortly after the Energy Star program began way back in March 15, 1992.  One of the first results of green computing was the “ Sleep mode” function of computer monitors.  As the concept developed, green computing began to encompass thin client solutions, energy cost, accounting, virtualization practices, e-Waste, etc.

  Why Go Green? Climate Change: •CO2 and other emissions are causing global climate and environmental damage. • Preserving the planet is a valid goal because it aims to preserve life.  Savings: • Green computing can lead to serious cost savings overtime. • Reductions in energy costs from servers, cooling, and lighting are generating serious savings for many corporations.

  Why Go Green?  Reliabilityof Power: • As energy demands in the world go up, energy supply is declining or flat. • Energy efficient systems helps ensure healthy power systems.  Sustainability: • The larger value of going green relates to maintaining the health of the environment.

  Green Computing Approach Turn off the computer when not in use.  Turn off the monitor when not in use.  Use LCDs instead of CRTs as they are more power efficient.  Reduce Power Consumption.  Goodbye screen saver  Standby modes  Power off

  Green Computing Approach Optimize computer performance.  Reduce paper consumption.  Use email,electronic archiving  Don't print until required  Recycle  Discard used or unwanted electronic equipment in a convenient and environmentally responsible manner  E-waste management

  Advantages: Energy saving Environmental Friendly Ameans to a better corporate image. Cost-effective(pays over time) Conserving Resources Reduce the risk existing in laptops

  Disadvantages High Start upcost Not readily available Still in experimental stages Sacrifices performance for battery life Not for everyone

  Conclusion  Whilst theperformance and the breadth of application of computers is increasing, so too is our awareness of the cost and scarcity of the energy required to power them.  In terms of the environmental debate computing is definitely both part of the problem and part of the solution.  The computing industry is more prepared and far more competent than almost any other industry when it comes to facing and responding to rapid change.  Replacing old equipment with new and more efficient equipment is only effective if the efficiency difference is high.

  Case Study Energy consumptionis a major concern for businesses and the global population as a whole, and an important part of a bigger IT concern called total cost of ownership (TCO). One way to reduce TCO is to use server-based computing, a computing model in which applications run on a central back- end server and are displayed on desktop devices. Both PCs and thin clients can be used in a server-based computing environment; however thin clients are the preferred desktops for server- based computing. Thin-client devices are simple computers designed to run applications from a central server.e.g; both PCs and thin clients display the same commonly used Windows desktop interface to the end-user, and have the same features such as keyboard, mouse, serial and parallel ports and network connectivity.

  Case Study(cont') At the sametime, thin clients are very different.  They have lower microprocessor requirements and lower memory requirements than PCs while providing an identical end-user experience.  Thin clients are literally smaller, some the size of a CD case, and most lack removable drives (or any drives), making it impossible for those using them to steal electronic data on floppy disk or introduce viruses to the network.  In short, thin-client devices are designed to cost less than PCs to run and maintain.  Using thin client devices with server-based computing reduces TCO even more than server-based computing with PCs.  An additional factor makes thin-client devices even more attractive than PCs: they use significantly less power.

  Questions 1. How thinclients are better than PCs? Any One reason! 2. Why thin clients are preffered desktops for server based computing? 3. Is Green Computing need of the hour?If yes then how?
