2) EPEAT registered

EPEAT is a system which intends to help purchasers select, compare and evaluate electronic products on the basis of their environmental attributes. Rating of computers in categories of Gold, Silver and Bronze depends on the number of 51 environmental criteria they meet pertaining to energy conservation, product longevity, corporate performance, end-of-life management and elimination of sensitive materials.23 baseline criteria’s have to be meet for a product to be rated Bronze. For a product to be silver rated it must meet the required criteria plus 50% of the optional ones, while an EPEAT gold rated products meets 23 baseline criteria plus 75% of the remaining 28 optional criteria.

HOW should green computing be brought in limelight?

Not everybody can afford to install solar Panel or get a new Toyota Prius, but there’s definitely one place where we spend the majority of our day i.e. sitting in front of the keyboard, without radically changing our lifestyle we can take some few small steps which can go a long way towards reducing its negative impact on the environment. We definitely can make our computing Green; here are a few ways we can compute in a Planet positive way:

Shut Down vs. Sleep vs. Hibernate

Each of the three power-down states appears to shut off your computer, but they all work differently. Shut Down: This is the power-off state most of us are familiar with. When you shut down your computer, all your open programs close and the computer shuts down your operating system. A computer that’s shut down uses almost no power. However, when you want to use your computer again, you’ll have to turn it on and go through the typical boot-up process, waiting for your hardware to initialize and startup programs to load. Sleep: Also known as Sleep or Standby. In sleep mode, the computer enters a low-power state. Power is used to keep the computer’s state in memory, but other parts of the computer are shut down and won’t use any power. When you turn on the computer, it will snap back to life within just a few seconds. You won’t have to wait for it to boot up – everything will be right where you left off. However, this uses more power than shutting down or hibernating your computer. Hibernate: Your computer saves its current state to your hard drive, essentially dumping the contents of its RAM into a file on its hard drive. When you boot up the computer, it will load the previous state from your hard drive into its RAM. This allows you to save your computer’s state, including all your open programs and data, and come back to it later. It takes longer to resume from hibernate than sleep, but hibernate uses much less power than sleep. A computer that’s hibernating uses about the same amount of power as a computer that’s shut down.

If you put your computer to sleep and its battery becomes critically low, the computer will automatically go into hibernate mode to save your state. Freeware software’s worth not ignoring:-
1) WinOFF system
Freeware application WinOFF schedules Windows shutdown, restart, log off, hibernate, and other shutdown modes using a variety of scheduling criteria. For example, you can tell WinOFF to shut down Windows at a specific time, after a specific period, or when the CPU is idle or usage is low for a certain period of time. WinOFF even has several worthwhile shutdown options, like capturing a screenshot of the desktop before shut down or executing a program before shutdown. This application would come in especially handy when you need to keep your computer running into the night to finish a download or task, but you don't want the computer running for hours after the task has completed.
