Green Software

Hardware consumes energy, because software tells it to. Research in Green IT is directing its attention to software. Some topics of research:

  • Management: Development of energy-efficiency indicators for software. See [1].
  • Optimization: Finding energy-efficiency optimizations in existing software applications. See [3],[4].
  • Measurement: Decyphering the relationship between software functions and electricity consumption by hardware components. See [2],[5].

The Knowledge Network Green Software is an open community in which new experiences and insights about Green Software are shared between researchers and practitioners. See [6].

The Cluster Green Software is a research consortium including universities and companies in the Metropole Region Amsterdam that performs joint research on energy-consumption of software. See [7].
