Koen Mortelmans

I am a Belgium-based freelance journalist, mainly writing about energy, environment, construction and science.

I started writing for newspapers and magazines while still studying for my master’s degree in history, and documentation and library sciences, and for my bachelor’s degree in philosophy. In my twenties, I did some teaching and also spent some time doing historical research, mainly about the Ancien Régime period.

I have also written several books about the history of sports and leisure. I'm also an avid distance runner and cyclist. I write in Dutch and in English. I also speak French and some German.
