Green Computing-Embrace a Secure Future


ICT has now become an important department for the success ofany organisation. Most of the businesses rely on the many benefits computers provide by using computing resources to perform a multitude of tasks, including work, research, teaching and learning. However the IT department is usually always the one department that uses the most amount of power which in turn is an excessive amount of overhead for a business as well as a source for toxic waste. Making IT “Green” can not only save money but help save our world by making it a better place through reducing and/or eliminating wasteful practices and using nontoxic materials. While using ICT, many institutions are a source for excessive power use, excessive spending of resources, and uses many toxic materials. All of these items are bad practices and converting acompany’s IT department to a more streamlined green concept is far more cost effective as well as better use of resources. This paper examines the need and provides a guideline which highlights our responsibilities as computer users and encouragesus to take actions that maximize the usefulness of these amazing tools while minimizing the negative consequences that may occurduring their use.

1. What is Green Computing?
Green computing or green IT, refers to environmentally sustainable computing or IT. It is the study and practice of designing, manufacturing, using, and disposing of ICT —efficiently and effectively with minimal or no impact on theenvironment. Green IT also strives to achieve economic viability and improved system performance and use, while abiding by our social and ethical responsibilities. Thus, green IT includes the dimensions of environmental sustainability, the economics of energy efficiency, and the total cost of ownership, which includes the cost of disposal and recycling…It is important to understand the need of the study of green computing. It is a tool by which global warming can be control and reduce. The Global surface temperature increased by 0.74 ± 0.18 °C (1.33 ± 0.32 °F) during the 100 years ending in 2005. Most conspicuously, according to the latest IPCC report the global surface temperature will likely to rise a to 6.4 °C (2.0 to 11.5 °F) during the twenty-first century. 1.2 Global Effect

No matter what we do, global warming is going to have some effect on Earth. Here are the six deadliest effects of globalwarming. 1. Polar ice caps melting
2. Spread of disease
3. Warmer waters and more hurricanes
4. Increased probability and intensity of droughts and heat waves 5. Economic consequences
6. E-Waste
In IT department, it is observed that the people are unaware of the consequences of mishandling. It is observed that most of the computer energy is often wasteful. This is because we leave thecomputer ON even when it is not in use. The CPU and fan consume power; screen savers consume power even when the system is not in use. Insufficient power and cooling capacities can also results in loss of energy. It is observed that most of the datacenters don’t have sufficient cooling capacities. This results in environment pollution. This could be because of defects in Manufacturing techniques, packaging, disposal of computers and components. Another effect is because of toxicity. There are toxic chemicals used in the manufacturing of computers and components which can enter the food chain and water. Accordingto one source, “Information Technology energy demand is growing 12 times faster than the overall demand for energy” and“Data centers emit over 150 metric tons of CO2 per year, and the volume is increasing rapidly. (As a point of reference, a carproduces 18 pounds of CO2 for every gallon of gasoline it uses.)” It is the need of the hour to educate people about the...
