Green Computing It can be defined as the study and practice of designing, manufacturing, using, and disposing of computers, servers, and associated subsystems—such as monitors, printers, storage devices, and networking and communications systems—efficiently and effectively with minimal or no impact on the environment.
Goals of Green Computing are similar to that of greenchemistry.It aims at reducing use of hazardous materials, maximizeenergy efficiency and promote recyclability orbiodegradability of defunct products and factory waste.Green computing researchers look at key issues and topicsrelated to energy efficiency in computing and promotingenvironmentally friendly computer technologies andsystems include energy efficient use of computers, designof algorithms and systems for environmentally- friendlycomputer technologies.
Roads to Green Computing Green use — reducing the energy consumption of computers and other information systems as well as using them in an environmentally sound manner . Green disposal — refurbishing and reusing old computers and properly recycling unwanted computers and other electronic equipment . Green design — designing energy-efficient and environmentally sound components, computers, servers, cooling equipment, and data centers . Green manufacturing — manufacturing electronic components, computers, and other associated subsystems with minimal impact on the environment .
Facts about Computer energy use. Computer technology use accounts for 2% of anthropogenic CO2 . -Roughly equivalent to aviation industry . -IT energy usage will double next 4 years . For every 12 consumers who keep power settings enabled for their on their monitors and PCs, CO2 emissions equivalent to removing one average automobile from the road will be avoided. If left on 24x7 for one year, this same computer will consume 1,270 kilowatt hours of electricity—that’s enough to release 1,715 pounds of carbon dioxide into the atmosphere and the equivalent of driving 1,886 miles in the average car.
Datacenter Energy use Power used by servers, cooling and ancillary infrastructure in 2005 accounted for about 1.2 percent of the United States’ electrical usage—the equivalent in capacity terms of about five 1,000 MW power plants (Jonathan Koomey, Lawrence Berkeley National Laboratory). U.S. energy consumption by data centers is expected to almost double in the next five years (U.S. EPA). Data center power and cooling costs have increased 800% since 1996. (IBM/Consultant Studies). Over the next five years, it is expected that most U.S. data centers will spend as much on energy costs as on hardware, and twice as much as they currently do on server management and administration costs. (IBM/Consultant Studies).
Steps towards Green Computing Virtualization: Virtualization is the consolidation of servers and systems to reduce power consumption and energy utilization. It leads to usage of more than one system on a single piece of physical hardware. This allows for minimum power consumption and maximum cooling. Power Saving: Industry standards like ACPI design and manufacture computer components in such a way that they result in power controlling and saving.
Telecommuting: Employees working from homereduce the fuel emission that is created duringcommuting by vehicles. Moreover, there is reductionin overhead costs like light, electricity, etc. All thisresults in increased power and energy savings.VoIP: VoIP stands for Voice over Internet Protocol andresults in less telephone wiring and lower costs.
Cloud Computing Cloud computing means using number of computer servers through a network, which appears as they are one single coherent computer. Cloud Computing is a technique that can be used to save enormous cost on server hardware, administration and power consumption.
Power savings due to CloudComputing If companies adopt cloud computing, they can reduce the energy consumption of their IT and save money on energy bills. The research by Vedantrix and sponsored by AT&T, estimates that cloud computing could enable companies to save $12.3 billion off their energy bills. That translates into carbon emission savings of 85.7 million metric tons per year by 2020.
Steps towards Green computing Wipro had announced the launch of its new eco-friendly Wipro Greenware desktops, manufactured with materials completely free of deadly chemicals like polyvinyl chloride (PVC) and brominated flame retardants (BFRs) - for the first time in India. Microsoft had announced their next data center in Siberia. The temperature of Siberia is always below 0 degrees even in summer days. This will help in saving energy consumed by cooling devices. The University of Oxford employs monitoring and wake- on-LAN services to help the campus community reduce the energy consumed by idle computers.
WOL service Wake on Lan service was tested on 200 computers. If a computer left on all the time, an 80 watt computer and 25 watt monitor will currently cost about £110 in energy charges and cause 494 kg CO2 equivalent to be released into the atmosphere. With WOL service it was observed that cost of energy consumed was about£24 in energy charges and result in 106 kg CO2. With WOL service a department with 200 computers will save about £17,000 and 78,000 kg CO2 eq per annum.
Actions that should be undertakenby the Organizations Use of thin clients or centralized control of the desktop machines. Use of efficient OS. Red hat enterprise Linux 5 and 6 are termed as most efficient and power saving OS (better than Microsoft Windows Server and SUSE Enterprise Linux). Informing your staff about the power savings that has resulted due to their efforts. Have a separate department that would look for Power saving options.
Green ITConclusionWhile there are numerous applications and options available toachieve green IT goals, it is the willingness to use theseapplications that makes all the difference.To this end, a green IT team to be formed and need to be brokenwith teams like facilities, marketing, human resources, productionand operations working together to accomplish the same goal. 9/17/2012 ITM Business School, Kharghar
