Energy Efficiency

A Brief History

Although energy efficiency is now a primary concern in the United States, it has long been a concern in other countries less blessed with the same abundance of natural resources. However, the US has been readjusting its thinking about energy use as well as the pollution of the environment for decades now.

Although it goes beyond just the issue of green computing, an early program still going strong is Energy Star. This program was begun by the United States government in 1992. It was originally devised to make consumer devices like TVs and refrigerators more energy efficient. Subsequent to its implementation in the US, the program was adopted by Australia, Canada, Japan, New Zealand, Taiwan, and the European Union.

The Energy Star program promotes energy efficient products through its certification and product labeling. For instance, it is credited with giving the world the sleep mode for computer consoles. This simple idea is now seen in the operation of the most advanced multi-core processors, which can hibernate some of their processing cores when their computing power is unneeded, thus saving energy.

Increased consumer awareness of green computing is now fostered by organizations like Environmental Protection Agency and the Greener Electronics Council through programs like EPEAT (Electronic Product Environmental Assessment Tool). EPEAT is a ranking system that helps consumers compare and select desktop computers, notebooks and displays based on their environmental attributes.
