The energy consumption of information and communication technology (ICT) is still increasing. Since several concepts regarding hardware solutions for Green IT exist, the contribution of software to Green IT is still not well investigated. This comprises the production and the usage impact of software on energy consumption. In our paper, we discuss this(More)
The power consumption of ICT is still increasing. To date, it is not clear if the energy savings through ICT overbalance the energy consumption by ICT, or not. Where manifold efforts of Green IT address the environmental aspects of sustainability considering computer hardware, there is a lack of models, descriptions, or realizations in the area of computer(More)
In the field of information and computer technology (ICT), saving energy has its focus set on energy efficient hardware and its operation. Recently, efforts have also been made in the area of computer software. However, the development of energy efficient software requires metrics, which measure the software's energy consumption as well as models to monitor(More)

Caused by the movement to a sustainable development, Green IT is still a big trend and more than just a buzz phrase. Especially data centers are working on their own energy efficiency. Additionally, Green IT needs to involve end users as the ones who play a decisive role in the utilization phase of ICT1 devices as well as software products according to the(More)
