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 .
- Optimization: Finding energy-efficiency optimizations in existing software applications. See ,.
- Measurement: Decyphering the relationship between software functions and electricity consumption by hardware components. See ,.
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 .
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 .
