It is the study and practice of using computing resources efficiently by designing, manufacturing, using, and disposing of computers, servers, and associated subsystems (such as monitors, printers, storage devices, and [[networking]] and [[communication systems]]) with minimal or no impact on the environment. <!-- May want to revise as sentence comes across as wordy --> Green computing strives for economic practicality and improved system performance while satisfying social and ethical responsibilities. Green computing includes the dimensions of [[environmental sustainability]], [[energy efficiency]] [[economics]], and total cost of ownership (which includes the cost of disposals and [[recycling]]).\"<ref name=\"San Murugesan 2008, pp 24-33\">San Murugesan, \"Harnessing Green IT: Principles and Practices,\" IEEE ''IT Professional'', January-February 2008, pp 24-33.</ref> <!--If this is a quote please place quotation mark at beginning; otherwise, please delete-->\n\nGreen computing can be made more sustainable in several ways including:\n\n* Placing the computer in hibernation mode<!-- May want to expand on what hibernating is -->\n* Switching the computer screen off instead of using screensavers\n* Turning the computer off when it is not in use\n\nEach of these examples can save power. More efficient coding means computers use less power and need less powerful hardware.\n\n== Energy-efficient computers ==\n\nThe maker of the low cost [[Inveneo]] computer claims to use one-sixth as much [[electricity]] as a typical personal computer.[http://web.archive.org/web/20090430183046/http://www.tectonic.co.za:80/wordpress/?p=1450]<!-- I would expand on this and state how they use less electricity than a typical PC -->\n\n== Energy Efficient IT Architecture ==\n\nUsing low power disk-less thin clients can save considerable power.\n\nOne way of doing that with Open Source Software is to use the [http://www.ltsp.org/ Linux Terminal Server Project (LTSP)] Software.\n\nIn their own words \"LTSP is an add-on package for Linux that allows you to connect lots of low-powered thin-client terminals to a Linux server.
