Stefan Pfenninger

I am an interdisciplinary researcher in renewable energy and environmental science, based in the Climate Policy Group at ETH Zürich’s Department of Environmental Systems Science. My current research focus is the global transition to a 100% clean and renewable energy system, and the technical, economic and policy barriers on the way to that goal.

In the course of my work I created and lead development of the open-source energy system modelling tool Calliope. I am also the creator and lead developer of the Renewables.ninja platform to simulate wind and solar power plants worldwide.
