In the advancing world now, technology had been revolitionized since the first computers Z1 Computer invented by Konrad Zuse in 1936 until now we got the most advanced computers ever invented by humans. But every technology got its pros and cons including the computers technology. As many did not aware that computers is the most biggest contributor of pollution nowadays and many wonders how those computers that runs silently in our house or office can pollute the world. To reduce the IT’s environmental problem, we need to call upon all computer users to green their IT system as well as the way they use their system. What can cause the green house effect? How does the computers effecting the world temperature? How can we control the pollution? DEFINITION
Green computing is the responsible and practice of using a computing resources more efficiently while increasing or maintaining its performance time by time without increasing its power usage, electronic waste and heat. Sustainable green computers will require the integration of power management, virtualization, improved cooling technology, recycling, electronic waste disposal, and optimization of the IT infrastucture to meet sustainability requirements. According to the article of Green Computing in the www.techopedia.com, “Many IT manufacturers and vendors are continuously investing in designing energy efficient computing devices, reducing the use of dangerous materials, and encouraging the recyclability of digital devices and printing paper. Green computing practices were primarily introduced by the Environmental Protection Agency in 1992 with the launch of the Energy Star program.” As stated in Green Computing Saves Green written by Priya Rana “This environmentally sustainable computing can be defined as "the study and practice of designing, manufacturing, using, and disposing of computers and associated subsystems such as monitors, printers, storage devices, networking, and communication systems efficiently and effectively with no impact on the environment”
GREEN COMPUTING CRITERIAS
1. Power Management
Desktop computer power supplies (PSUs) are generally 70–75% efficient, dissipating the remaining energy as heat. Turn off the power supply if its not in use to prevent excess energy consumptions. -Storage
Smaller form factor hard disk drives often consume less power per gigabyte than physically larger drives. With no moving parts, power consumption may be reduced somewhat for low capacity flash based devices. -Display
LCD monitors typically use a cold-cathode fluorescent bulb to provide light for the display. Some newer displays use an array of light-emitting diodes (LEDs) in place of the fluorescent bulb, which reduces the amount of electricity used by the display. 2. Materials Recycling
Computer systems that have outlived their particular function can be repurposed, or donated to various charities and non-profit organizations. Recycling computing equipment can keep harmful materials such as lead, mercury, and hexavalent chromium out of landfills. 3. Telecommuting
Teleconferencing and telepresence technologies are often implemented in green computing initiatives. The advantages are many; increased worker satisfaction, reduction of greenhouse gas emissions related to travel, and increased profit margins as a result of lower overhead costs for office space, heat, lighting, etc.
It is important to design an appropriate data center because that is where it hosts all the supporting infrastructure to the various computer services, and an appropriate structure will allow good energy savings, space and costs in the medium and / or long period, each company must choose the design...
