Saving energy is an important aspect, when planning new compute centres. For real "Green Computing" not only the hardware should use the electrical power most efficiently, but also the used software should make use of the computational resources as efficiently as possible. This is not achieved automatically but investment in brain power is necessary to support code improvement. A short overview about the German research High-Performance-Computing-infrastructure is given, and the structure of the embedded "Hessian Competence Centre for High Performance Computing", which was funded to close the "software gap" in Hesse. The example of tuning a frequently used and extended research code illustrates the necessity and power of collaboration of computer scientists and research-code developers, and the necessity to install and provide procedures for a continuous performance tuning work-flow, including further education in HPC-techniques.
