  • Used computers dumped before disposal
  • Green building is required to enhance a complete green environment around. And to save energies by getting it from the nature, example solar plants for electricity....

  • GREEN COMPUTING“Is the study and practice ofdesigning, manufacturing, using, and disposingof computers, servers, and associatedsubsystems—such as monitors, printers, storagedevices, and networking and communicationssystems - efficiently and effectively with minimalor no impact on the environment“. It is also beencalled as Green IT.
  • TO SUMMARIZE• Green computing is a novel and an innovative trend in the world of computing which has minimum or no impact on the environment.• Green computing has introduced a range of equipments and technologies which help in limiting the impact on the environment.• Use of EUPs help in different aspects of the computing world help in recognizing the areas for improvement.
  • GREEN IT IS CONCERNED WITH Energy Efficient IT Architecture Advanced Power and Cooling Integration with Building and Landscape Architecture Using IT to enhance environmental education and responsibility Using IT to save energy
  • WHY GREEN COMPUTING computer energy is often wasteful  leaving the computer on when not in use (CPU and fan consume power, screen savers consume power) printing is often wasteful  many of us print out useless things for some sake  printing out partial drafts  for a “paperless” society, we tend to use more paper today than before computer-prevalence
  • WHY GREEN COMPUTING pollution  manufacturing techniques  packaging  disposal of computers and components Toxicity  There are toxic chemicals used in the manufacturing of computers and components which can enter the food chain and water!
  • E NERGY U SE OF PC S CPU uses 120 Watts CRT uses 150 Watts  8 hours of usage, 5 days a week = 562 KWatts  if the computer is left on all the time without proper power saver modes, this can lead to 1,600 Kwatts
  • Energy use comes from electrical current to run the CPU, motherboard, memory running the fan and spinning the disk(s) monitor (CRTs consume more power than any other computer component) printers
  • DISPOSAL 183 million computers were sold in 2004 (674 million cell phones!) New users in China (178 million by 2012) and India (80 million by 2012) will require the creation of new computers Disposal of these devices constituted 20-50 million tons per year (about 5% of the total waste of the planet)  this waste is called e-waste  where are we going to put all of it?
  • L AND F ILLS Europe has outlawed using landfills for computer components  the US and Europe export a lot of e-waste to Asian landfills (especially China even though China has outlawed the importing of e-waste)  in addition, incineration of computer components leads to air pollution and airborne toxins
  • PRACTICES TO BE FOLLOWED Putting down the CPU and all peripherals during extended periods of inactivity to reduce the energy consumption. Performance of computer-related tasks during contiguous, intensive blocks of time, leaving hardware off at other times to improve the efficiency in the work by saving the energy. Powering-up and powering-down all the energy- intensive peripherals such as laser printers according to need to reduce energy consumption. Usage of notebook computers in the place of desktop computers whenever possible to enhance cost reduction and energy savings.
  • PRACTICES TO BE FOLLOWED Usage of liquid-crystal-display (LCD) monitors instead cathode-ray-tube (CRT) monitors not only decrease the energy consumption but also to improve the efficiency of work and hence the cost reduction also takes place. power-management features to turn off hard drives and displays after the set minutes of inactivity. Minimize the use of paper and adapt proper recycling method of waste papers. The e-waste is to be disposed in the proper way according to federal, state and local regulations to avoid toxic pollutions.
  • GREEN BUILDINGS Reduces the total ownership cost of facilities Improve energy efficiency and water conservation Provides safety, healthy and productive built environments Promotes sustainable environmental stewardship
  • CONCLUSIONS Green IT  IT is a major power consumer  A significant percentage of the power is wasted  Opportunities exist to dramatically improve IT energy efficiency  IT can be a very beneficial part of the Green movement .
  • Recycle - DonationsMake sure your system has the correct OSlicense. Windows Genuine hologram label,MacOS, or alternative FOSS OS like Linux.Donate with original media anddocumentation.Wipe the hard drive with utility like DBAN. Donot format as it does not remove data only thetable of contents. 16
  • Recycle – Disposeo Wipe your hard drive with DBAN or comparable tool.o Batteries can be recycled at many stores.o Electronics drives sponsored by local municipalities.o Wake County hazardous materials drop off o Location and hours: 9029 Deponie Dr Raleigh NC 27614 Mon – Sat, 8am - 4pm 17
  • Reduce - PapereFAX – Send and receive faxes over theinternetUse both sides of paper. Save single sidedsheets for reuse.Add a duplexer to your printer or use duplexmode.Shred and recycle paper that can no longer beused. 18
  • Reduce - PowerUse Energy Star approved electronicsUse OS power saving settings. • Turn off display • Stop hard drives • Have computer go into sleep or hibernate modeHave computer go into sleep or hibernate mode whenleaving the office for an hour or more.Turn off devices in stand by mode at the end of day.Unplug devices that have a remote control. 19
  • Reduce - PowerUse the class of device that balances power requirementswith what you need to do.Less Power • Smart Phone • Tablet • Netbook • Notebook • Desktop replacement laptop • Desktop computer • Most server class computersMore PowerLaptops instead of desktop computers gives portability andreduces power usage. Most desktops are 250W+, mostlaptops are 65-90W. 20
  • Reduce - PowerThe monster file server. Most business servers are used tostore and serve files. Most servers are over powered for thissimple task.Server used at my home: File server, name services, audiostreaming. Powered by Via C9 processor. 12W idle, 37Wmax.Home DVR server: TV recording, playback, and streaming.40W at idle, 58W max.Consider using network attached storage instead of a fileserver. Seagate BlackArmor NAS uses 15-20W and isavailable at 21
  • Reduce DependenceConsider local point powergeneration.30% tax credit for solar heat orphotovoltaic systems.Most systems will still require 7-12years for break even. 22
