Understanding Green Understanding Green Computing Computing • Since the First Earth day that took place in

1970, our awareness about environmental issues has increased many folds. Some of them are:

• Global Warming resulting in heat waves, Global Warming resulting in heat waves, droughts, rise in global temperature and more.droughts, rise in global temperature and more.

• Hazardous Materials like lead, mercuryHazardous Materials like lead, mercury• Earliest initiative towards Green Computing Earliest initiative towards Green Computing

Green Computing: An Environmental Necessity

Green Computing

Defining Green ComputingDefining Green Computing

• Initiative taken in the direction of computing resources which produce waste energy that is adding to global warming is Green computing also known as Green IT. It is about::

• Using computer resources in Using computer resources in environmentally friendly way environmentally friendly way

• Recycling digital devices Recycling digital devices • Reducing use of hazardous materialsReducing use of hazardous materials


Need for Green ComputingNeed for Green Computing

• An average PC wastes half the energy it consumes which not only results in additional electricity bill but the wasted electricity contributes to global warming.

• Just by using the power management feature of a PC or laptop and buying energy efficient systems, impact of computers on the environment can be reduced.



Some green computing practices are as follows:•Power-down CPU, monitor and all peripherals after use. •Energy-intensive peripherals like laser printers can be powered as per need.•LCD and LED monitors can be used. •Using notebook computers.



• Disposal of e-waste according to federal, state and local regulations.

• Employ alternative energy sources for computing workstations, servers, networks and data centers.

• Reducing carbon footprints.• Making use of technology wisely.• Evaluating systems and technology before

adopting it.


Importance of Green ComputingImportance of Green Computing

• Business organizations are waking and also making an effort in the direction of green computing.

• There are energy smart desktops from DELL like OptiPlex 755 Energy Smart MT, OptiPlex 755 Energy Smart USFF, DELL Precision 490 and many more.

• It encourages the use of environmental friendly products in an efficient way.


Importance of Green ComputingImportance of Green Computing

• Green Computing must be promoted to Green Computing must be promoted to save environment. For this we should save environment. For this we should encourage:encourage:• Green TechnologyGreen Technology• Green ProductsGreen Products• Green disposal Green disposal • Green ManufacturingGreen Manufacturing• Green DesignGreen Design• Green ServicesGreen Services


Path towards GreenPath towards Green

• Green computing is somewhat related to other movements like reducing the use of environmentally hazardous materials like CFCs, using recyclable materials, minimizing use of non-biodegradable components, and encouraging use of sustainable resources.

• Green computing basically takes into account economic viability, social responsibility and environmental impacts.


Path towards GreenPath towards Green• Following Green IT regulations like EPEAT,

Energy Star 4.0 standard, RoHS Directive, and W.E.E.E. Law.

• Industry association for Green Computing: Uptime Institute Inc., Climate Savers Computing Initiative and Green Grid.

• Green Data Centre Initiative like energy conservation and virtualization.

• Adopting eco-friendly practices like refurbishing and recycling.


Issues and ChallengesIssues and Challenges

• In the last ten years, computer-related energy consumption has increased five-fold.

• The recent computing efforts that are coming up like pervasive computing, nano computing, quantum computing, ubiquitous computing and many more should keep the requirements of green computing in mind and develop there environmental friendly products.


Issues and ChallengesIssues and Challenges

• Efforts should be made to have products which utilize the enormous energy available in the form of waste energy, solar energy, nuclear energy and many more forms of energy.

• Education institutions can make students aware about Green Computing through seminars and programs.



SummarySummary• Green Computing is demand of the society Green Computing is demand of the society

and environment.and environment.• Computer penetration is increasing every Computer penetration is increasing every

minute and so is pollution.minute and so is pollution.• Government also needs to actively work in Government also needs to actively work in

this direction. this direction. • Various regulations and laws will soon

have to be in place that will force the use of IT equipment that meets needed energy efficiency requirements.
