Green Computing
green computing and green IT, it refers to sustainable environmental development computer or computer. It is "the study and practice of design, manufacture, use and disposal of computers, servers and associated subsystems, such as monitors, printers, storage devices and networking and communication systems efficiently and effectively with minimal or no impact on the environment. Green IT also strives to achieve economic viability and improved system performance and use, while respecting our social and ethical responsibilities. Is a result of global warming but in reality is' Desktop warming.
To comprehensively and effectively address the environmental impacts of computing and IT, we must adopt a holistic approach and imagine that the entire life cycle of green environmental sustainability over the four complementary ways:
- Use Green – Reduce the energy consumption of computers and information from other systems and use in an environmentally sound
- Green provision – the renovation and reuse of old computers and computer recycling properly and other unwanted electronic equipment
- Green Design – The design of low power components and environmentally friendly, computers, servers, cooling and data center
- Green Manufacturing – Manufacture of electronic components, computers and other subsystems associated with minimal impact on the environment
Background information: The agency of the U.S. Environmental Protection launched Energy Star program, a voluntary labeling program in 1992, which aims to promote and recognize energy efficiency in monitors, climate control equipment, and other technologies. This led to the adoption Standby widespread in computers and electronics popular consumer electronics. The term "green computing" was probably introduced after the Energy Star program began, there are several USENET posts dating back to 1992, using the term in this way. At the same time, the Swedish organization TCO Development launched the TCO certification program for the development of magnetic and electrical emissions COMPUTER CRT screens, this program was later expanded to cover the criteria on energy consumption, ergonomics and use of hazardous materials in construction. The title = "Organization for Economic Cooperation and Development "> Organization for Economic Cooperation and Development (OECD) has published a survey of more than 90 government and industry initiatives "Green ICT", ie information and communication technologies, environment and climate change. The report concludes that efforts are concentrated Green ICT in place of the fight against global warming and environmental degradation through the use of ICT applications. Overall, only 20% of the initiatives with measurable goals, with government programs, including more often than associations.Many governmental business organizations have continued to apply the rules and regulations that encourage green computing. The Energy Star program was revised in October 2006 to include stricter efficiency requirements for computers, along with a tiered system of classification of approved products. More than 26 U.S. States that have established recycling programs statewide for obsolete equipment and equipment consumer electronics. "Green Computing Impact Organization (GCIO) is a nonprofit organization dedicated to helping end users of products Being environmentally responsible computer in encouraging the community of environmental leaders are concerned that they share their time, resources and purchasing power to educate, expand the use and improve efficiency, computer products and green services. Members work to increase the ROI of green IT products through a deeper understanding of the real measurable and sustainable savings achieved by their peers, the application of a drive towards efficiency products suppliers, keeping records of the community of the savings generated, and the power of a negotiating group.
It is increasingly understood that the way in we behave as a society is environmentally unsustainable, causing irreparable damage to our planet. Rising energy prices, along with government-imposed levies carbon production, are increasingly impact on the cost of doing business, so many of the current business practices economically unsustainable. It is becoming increasingly important for all businesses to act (and be seen to act) in an environmentally responsible, both to fulfill their legal and moral obligations, but also to strengthen the brand and image for business improvement. The companies compete in an increasingly green market and avoid real growth and financial penalties which increasingly perceived against the production of carbon.
IT has a major role in this. With the increasing drive to centralized data centers with the mega huge growth in power hungry blade technologies in some companies, and with a change to an architecture distributed equally hungry for power in others, the role of corporate IT is causing an exponential increase in energy demand, and with it, you have to bear the associated cost increases.
How to contribute Green Computing
As computers play an increasing role in our lives, energy demands, costs, and waste
are increasing dramatically. Consider the following from the Climate Savers Computing
Initiative:
In a typical desktop computer, nearly half power coming out of the wall is wasted
and never reaches the processor, memory, disks, or other components. The heat from inefficient computers can increase the demand for air conditioners and cooling systems, making the computing equipment even more expensive. Although most desktop computers today are able to automatically transition to a sleep or hibernation state when inactive, about 90 percent of systems have this function disabled. About 25 percent of the electricity used to power home electronics, computers, DVD players, stereos, televisions, is consumed while the products are turned off. Turn the computer off at night to run only eight hours a day, you'll reduce energy consumption by 810 kWh a year and a net savings of 67 percent. Buy flat screen monitors, which use much less energy and are not as tough in his eyes as a compatible CRTs.Purchase Energy Star equipment. Note that the models of laptop uses much less energy than desktop units. Connect your computer to a surge protector with a major takeover, which automatically detects when the computer is not in use and power cuts to it and all its peripherals. Plan your activities with the computer so you can do everything at once, keep your computer off at
other times. Consider a small monitor, a screen of 14 inch uses 40 percent less energy than a 17-inch. On standby / sleep mode and power management settings on your computer. Forgo the screen saver "that does not save energy or screen unless you are using an old monochrome monitor. Review draft documents and e electronic on-screen instead of printing. Turn off the monitor when not in use instead of using screen savers. Consider using a printer inkjet, although a bit slower than laser printers, inkjet use 80-90 percent less energy. buy and vegetable oil-based inks
produced from renewable resources, require less hazardous solvents, and often
produce brighter, cleaner colors. Turn off all printers and peripherals unless you are using. Do not leave the computer running overnight or on weekends. Choose dark background for bright color screen, shows more power consumption. Reduce the light level in your room when you are working on your computer.
The network and share printers whenever possible. Print on paper containing recycled material. Look for non-chlorine bleached paper with 50 to 100 percent post-consumer waste. Use double-sided printing capabilities. Communications by email as an alternative to paper notes and documents by fax.
Create Green Machines:
Activation the energy management features on your computer saves energy and money while helping the environment. His dream team and configuring Hibernate are two of the most effective ways for you to make your computer more environmentally friendly. You can activate these functions manually or through your operating system pre-configure the power management.
Standby
Sleep or standby mode saves energy by cutting off power to the screen, hard drive, and peripherals. After a predetermined period of inactivity, the computer switches to a low-power state. Moving the mouse or press any key on the computer, you come out of sleep mode and takes his team back to its previous operating state. Sleep mode is a particularly effective way to conserve battery power on a laptop. However, if your computer loses power for any reason, while in sleep mode, can lose unsaved work.
Hibernation Mode
Hibernate mode saves energy and protects your work by copying system data to a reserved area on the hard drive and then completely turning off the computer. It also reduces component wear. When you reconnect, your files and documents appear on the desktop just as you left. Be sure to configure the system to go into hibernation mode automatically each time your energy battery reaches a critically low level.
