Green computing is the term used to denote efficient use of resources in computing. It Is also known as Green IT. Green Computing is “ Where organizations adopt a policy of ensuring that the setup and operations of Information Technology produces the minimal carbon footprint”.
One of the earliest initiatives toward green computing in the United States was the voluntary labeling program known as Energy Star. Government regulation, however well-intentioned, is only part of an overall green computing philosophy. The work habits of computer users and businesses can be modified to minimize adverse impact on the global environment. Here are some steps that can be taken:
•Power-down the CPU and all peripherals during extended periods of inactivity.
•Try to do computer-related tasks during contiguous, intensive blocks of time, leaving hardware off at other times.
•Power-up and power-down energy-intensive peripherals such as laser printers according to need.
•Use liquid-crystal-display (LCD) monitors rather than cathode-ray-tube (CRT) monitors.
•Use notebook computers rather than desktop computers whenever possible.
•Use the power-management features to turn off hard drives and displays after several minutes of inactivity.
•Minimize the use of paper and properly recycle waste paper.
•Dispose of e-waste according to federal, state and local regulations.
•Employ alternative energy sources for computing workstations, servers, networks and data centers.
