Green Computing
In the current global era, people prefer to do their work with a computer. In addition to fast, also Computers also facilitate a better job. But somehow how much energy we use that has been working during the day with full use computers. Besides, too long in front of the computer also cause side effects for the computer user.
You know what it is "Green Computing?" 
"Green computing is the study and practice of using computing resources efficiently. The primary objective of such a program is to account for the triple bottom line, an expanded spectrum of values and criteria for measuring organizational (and societal) success. The goals are similar to green chemistry; reduce the use of hazardous materials, maximize energy efficiency during the product's lifetime, and promote recyclability or biodegradability of defunct products and factory waste. "
Essentially is a practical use, production processes, and development of computers and all things related to the page more efficiently and can be environmentally friendly.
Some Green Computing method approach so that more environmentally friendly computing system in the following:
• Utilization of alternative energy
o By using alternative energy sources can be driven computing system, such as using nuclear energy, hydroelectric, windmill, etc.. The use of other energy source that is of interest to the human instance of a project Twibright Exciter.
2. The use of virtualization technology System
o It is already time in the current system we use virtualization technology. This system allows us to run a process in two or more logical computer hardware units in one main processor or CPU. So the virtualization system with an administrator will be easier to combine multiple physical CPU to the system in the form of a Virtual Machine that is far more powerful. Of course, this could reduce the overall number of resources available. Besides, of course *** reduce the heat radiation that arise from a number of existing hardware. Imagine if you are in the Data Center space that might be hundreds of computers and radiation heat up enough page needs cooling system in the space page and felt quite hot, too.
o System virtualization is now popular with the Desktop virtualization and server virtualization.
3. The use of resources
o modern computing at this time the facilities are equipped Advance Configuration and Power Interface, which allows an operating system directly controls the power saving factor of the computer hardware page. For example you can set the monitor or hard disk will automatically be idle (in the circumstances there is no activity). Besides, you can set the system power management page in the computer BIOS and other features in each product.
4. Use of the Low Power Hardware
o Currently, many products that use computer resources are low. But this will not fit when you use the computer for gaming, video editing, and applications that require large resources. If you only need a system for office and just browsing the Internet, computer hardware with a minimalist this is more than enough, and certainly can save your budget.
5. Recycled utilization system
o When the computer is outdated, but still can usually return sparepart the work may still be used as a source for other computers. While I have been so damaged that there can sparepart in recycling again. Usually this occurs in developed countries like the United States and Europe.
6. Use of Mobility System
o Infrastructure existing cable channels such as telephone at this time may be reduced owing to the innovations in information technology where we have been able to use communication VOIP (Voice Over Internet Protocol). Indirectly we are reducing the use of materials from the metal structure of the dangerous cable page.
No wonder that the regulation green computing method has been born in some developed countries like the United States spent about Energy Star program in 1992. Then in Europe have Swedish Confederation of Professional Employees menyertifikasi products that computer equipment and offices to fit the standard basic rules. And we know the RoHS (Restriction of Hazardous Substances), which we usually find in a product which means that the product page using the materials that have been eligible to apply.
