Welcome to the green software wiki

Green software refers to environmentally sustainable software. This wiki covers all different aspects of green software.

Green software

In Harnessing Green IT: Principles and Practices a definition of green IT as provided by Murugesan is the study and practice of designing, manufacturing, using and disposing of computers, servers, and associated subsystems—such as monitors, printers, storage devices, and networking and communications systems—efficiently and effectively with minimal or no impact on the environment. In <reference naar eigen paper> the definition for green software is introduced as being Computer software that can be developed and used efficiently and effectively with minimal or no impact to the environment

There are different reasons to create green IT, but is often part of a sustainability strategy. In this strategy can be a special section on environmental strategies or green strategy.

Green implementation

For a product to be considered green, its production process has to keep its emission of greenhouses gases and consumption of non-renewable resources to a minimum.

Green operation

Different ways for IT to decrease its own operation carbon footprint is by direct and indirect savings.

In direct savings the goal is to reduce the carbon footprint an IT artifact causes. Systems that consume as little energy as possible during production and operation are said to be energy efficient. Direct savings can increase the energy efficiency of a software system. For ways to increase the energy efficiency of software, see the best practices for energy efficient software.

Indirect savings are done by influencing artifacts that on their own influence the energy consumption of an IT artifact. Ways to save energy indirectly include raising awareness or adding regulating and information gathering tools to a system added with the sole purpose to help accomplish direct savings.
