Green Computing: Computing devices and supporting facilities with high efficiency, energy saving and low power consumption. On the premise of ensuring the reliability of information services, computing resources are allocated reasonably. New systems and applications with low cost and low energy consumption for sustainable development
Green computing is the use of computers and related resources in an environmentally responsible manner. Green computing includes the use of energy-efficient central processing units (cpus), servers and peripherals to reduce resource consumption and properly dispose of e-waste
Leading the way toward green computing in the United States is a voluntary labeling program known as Energy Star. The campaign was initiated by the Environmental Protection Agency in 1992 to improve the efficiency of all types of hardware. The Energy Star label is often found on devices such as laptops and monitors. Similar schemes are already under way in Europe and Asia.
Adopt some of the following measures to reduce environmental impact:
Turn off the CPU and all peripheral devices when the computer is idle for a long period of time
Complete computer-related tasks in a continuous, intensive block of time, and stop hardware work at other times
Turn on or off high-energy peripheral devices, such as laser printers, as required
Use liquid crystal display (LCD) instead of cathode ray tube (CRT) display
Use laptops instead of desktop computers where possible
Use the power management function to shut down the hard drive and monitor after the computer has been idle for several minutes
Reduce the amount of paper used and properly reuse waste paper
Dispose of e-waste in accordance with government and local regulations
Adopt alternative energy sources within computer workstations, servers, networks and data centres
