Green computing involves designing, manufacturing, and disposing of computers and peripherals efficiently and sustainably. It aims to reduce energy usage and environmental impact. Green computing grew from initiatives like Energy Star in the 1990s and addresses challenges like rising power consumption from increasing circuit speeds. Data centers now consume huge amounts of energy. Implementing green computing involves virtualization, power management, cloud computing, and telecommuting to reduce usage. Conferences like ICGREEN promote eco-friendly technologies and responsible IT behavior. Recent examples of green computing implementations include low-power devices like Blackle and Fit-PC.

3. Origin
● In 1992, the U.S Environmental protection Agency
launched Energy star.
● green computing" -coined shortly after the Energy Star
program.
● Swedish government launched TOC Program
concurrently.
● Later TOC program developed to Ergonomics

5. Current scenario
● Energy provisioning –most important issue
● circuit speed increases-power consumption
grows
● Low power consumption -second greatest
challenge for the industry
● The cost of energy and increases in IT power
requirements increasing day by day
