Green computing is very much related to other similar movements like reducing the use of environmentally hazardous materials like CFCs, promoting the use of recyclable materials, minimizing use of non-biodegradable components, and encouraging use of sustainable resources.
One of the earliest initiatives toward green computing in the United States was the voluntary labeling program known as Energy Star. It was conceived by the Environmental Protection Agency (EPA) in 1992 to promote energy efficiency in various appliances, such as laptops, washers, dryers, and refrigerators.
Organizations use the Green Computing Lifecycle when designing and implementing green computing technologies. The stages in the Green Computing Lifecycle include Strategy, Design, Implementation, Operations and Continual Improvements.
Currently, one of the popular green computing groups is tactical increment lists. This group applies and uses green computing philosophies mainly to save up on costs rather than save the environment. This green computing concept emerged naturally as businesses find themselves under pressure to maximize resources in order to compete effectively in the market. Interestingly, the green computing movement arose mainly from economic sentiments rather than political pressure.
