Abstract
Due to tremendous growth of Industrial activities throughout the globe, the climate of the earth is gradually changing. The Increase awareness of climate change and more concern for the environment, has forced the big industries to review their environmental credentials. The Global IT sector, for example, accounts for between two and three percent of the world’s total carbon dioxide emissions which contribute towards global warming and climate change. So if the IT companies are increasing exponentially then the global warming will be more and more. Keeping all these facts the companies throughout the world are now paying more attention to Green IT as an initiative towards cost savings and a greener environment. However, a significant percentage of total population of the globe unaware of the various good practices in ICT towards Green IT. The concept of green computing has begun to spread in the past few years, gaining increasing popularity. Besides the widespread sensitivity to ecological issues, such interest also stems from economic needs, since both energy costs and electrical requirements of IT industry around the world show a continuously growing trend.
INTRODUCTION
Due to huge amount of carbon emissions from different Industries the ozone layer getting thinner and which is dangerous for human body. The environmentalists of various developed nations campaigns about educating the masses of the importance of reducing carbon emissions thereby helping the preservation of the ozone layer. Preservation of ozone layer is one issue but there are more issues along with this. Those issues has been worrying the environmentalists. One of those issues is being depletion of natural resources which causes increase in CO2 emissions, pollution, wastage of resources, and so on. It is now the high time we start saving clean air, fuel sources, water and soil for the future generations along with saving money and assets for them.
Green computing refers to environmentally sustainable computing. Green computing attempts to reduce the cost and power consumption of IT system and maximize energy efficiency during the system’s lifetime.
GREEN COMPUTING AND GREEN IT
In the context of manufacturing, green computing is to reduce the use of hazardous materials, maximize energy efficiency during the product's lifetime, and promote the recyclability. Research continues into key areas such as making the use of computers as energy-efficient as possible, and designing algorithms and systems for efficiency-related computer technologies.
“Green IT” refers to all IT solutions that save energy at various levels of use. These include (i) hardware, (ii) software and (iii) services.
The Hardware should be energy-efficient desktop PCs, thin-client architectures. In the software and service area, there is significant potential in virtualization, in solutions for dynamic capacity management and data-center planning, and in storage-system off shoring. One cannot purchase or order Green IT directly, but intelligent solutions are available that contribute to sustainability. Green IT comprises initiatives and strategies that reduce the environmental footprint of technology. This arises from reductions in energy use and consumables, including hardware, electricity, fuel and paper – among others. Because of these reductions, Green IT initiatives also produce cost savings in energy use, purchases,
Virtualizing
The traditional model of dedicated servers to specific computing functions has been broadly adopted due to resilience based on isolation. Many software vendors such as Microsoft have recommended dedicated servers for the various utility tasks such as domain controllers, file servers, email and database servers. This has led to a proliferation of servers in the data-centers, spiralling requirements for power and air-conditioning. With this large expansion of server estate has become increased problems of standardization and patch management further driving up the total cost of ownership. Many of the servers in typical traditional production environments can operate way below optimal capacity in terms of memory, CPU and disk.
Adopting a Green Computing Strategy does not mean a move away from the logical model, only the physical model. Where servers are typically underutilized, virtualization can be used to slice up a single physical machine into a number of virtual servers. From a green perspective the net result is normally a substantial reduced in power and air conditioning requirements saving energy, money and thus reducing the carbon footprint of the server estate.
GREEN COMPUTING AND PRIVACY ISSUES
The recycling of old computers raises an important privacy issue. The old storage devices still hold private information, such as emails, passwords and credit card numbers. The files that users think they delete from the old hard drive can be recovered and used again, merely by someone using software that is available freely on the Internet. Scary stuff! For this reason, some companies store old systems that are out of service or outdated because software is not available, or compatible with old operating systems, like Windows 3.1, to wipe the data.
CONCLUSIONS
Green computing represents a responsible way to address the issue of global warming. By adopting green computing practices, business leaders can contribute positively to environmental stewardship and protect the environment while also reducing energy and paper costs. We have to ensure that Natural Resources are conserved and are available for our next generation to continue a way of life that is environment friendly. Design new creative framework useful for Collection, Utilization, Disposal of Electronic Waste. The strategy and plan for moving Data, System, Transactions, Services, People and Communication requires process and behavior change which can produce an effective green result.
To reduce the pressure on environment International Standards like ISO-14000 and Occupational Health and Safety Standard (OHSAS-18001) on environment management are already designed which needs to be implemented properly. These standards provide a framework and direction for accessing the IT related risk, nature of that risk and required control of measures should follow in day to day usage of all types of electronic devices. These are the good practices for implementation of Green IT initiatives. Everyone should become Green IT Innovator for cultural change and saving mankind from environmental pollution. Scraps created by massive use of IT has increased tremendously
