A review of green electronics research trends

To set the stage for the conference it is of interest to take a look back in order to try a look forward at potential upcoming research trends. For this purpose research topics addressed in Electronics Goes Green conferences since 2000 are quantitatively investigated with a keyword density analysis. The focus is on analysing the development of research topic clusters over time providing an expert review of selected topics to fathom cause and effect. A topic cycle at conferences may end because the underlying problem has been solved, is regarded as unsolvable or has been superseded. This cannot be analysed from numerical records alone but needs access to experienced experts active during the time investigated. Note that this is an extension of a previous conference presentation without an accessible publication record.
