The document is a report about green computing by a student named Yash Ramkrishna Govare for their Computer Science class. It discusses the introduction to green computing, the need for green computing in terms of wasteful energy usage, printing, pollution from manufacturing and disposal, and toxicity of chemicals. It then provides solutions to reduce energy consumption such as turning off computers when not in use and using energy efficient hardware. The document concludes by discussing solutions like reusing, refurbishing, and recycling electronics as well as the need for computer manufacturers to use more recyclable chemicals.

2. Introduction
Green computing is the environmentally responsibleand eco-friendlyuse of computers and
their resources. In broader terms, it is also defined as the study of designing,engineering,
manufacturing,using and disposing of computing devices in a way that reduces their
environmentalimpact. Computer designers, developers,manufacturing companies and
vendors are investingin developing green computing modules and devices by reducing the use
of hazardmaterials and improvingthe recycling process of computing and digital
modules.GreenComputing, also known as Green Technologyor Green IT, has quickly emerged
as the most effective means of utilising technology
Green computing practices include the developmentof environmentallygreen production
practices, efficient energy consumptioncomputers, usage of energy harvestingtechnologies,
and enhancing disposaland recycling procedures
In 1992 the Environmental Protection Agency (EPA) launched the Energy Star program that
boosted Green computing practices

3. Need Of Green Computing
 Computer energy is often wasteful
1. Leaving the computer on when not in use (CPU and fan consume power, screen savers
consume power )
 Printing is often wasteful
1. How many of you print out your email or meeting agendas
2. Printing out partial drafts
3. For a “paperless” society, we tend to use more paper today before computer-prevalence.
 Pollution
1. Manufacturing technique
2. Packaging
3. Disposal of computers and components
 Toxicity
1. There are toxic chemicals used in the manufacturing of computers and components which
can enter the food chain and water

4. Reducing Energy Consumption
oTurn off the computer when not in use, even if just for an hour.
oUse power saver mode
oUse hardware/software with the energy star label
oEnergy star is a “seal of approval” by the energy star organisation of
the government (the EPA)
oDon’t print unless necessary and you are ready.
oUse LCDs instead of CRTs as they are more power efficient

5. Solutions
o Reuse : Donate your computer components to people who may not have or have lesser quality computers like
inner city school,churches, libraries,thied world countries.
o Refubish: Rather than discarding your computer when the next generation is released, just get a new CPU and
memory chips- upgrade rather than replace, while you will still be discarded some components, you will retain
most of the computer system(e.g.,monitor,the system unit housing, cable)
o Recycleing: if companies can recycle the plastic and other components, this can greatly reduce waste and toxins.
o However, the harzadous material in e-waste can harm the recycle workers if they are not properly protected.
o Developed countries now have facilities for recycling e-waste.
o However, in Europe, the plastic are discarded instead of recycled because the flame retardant chemicals are too
toxic to work with.
o To resolve these problems, the computer manufacturers must start using recyclable chemicals
