Rapidly transitioning to clean and sustainable energy

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

Research spotlight: China's PV potential with pollution-free 1960s surface radiation

Using solar radiation data from 119 stations across China we show that photovoltaic electricity potential decreased on average by 11–15% between 1960 and 2015. Given the observed relation between surface radiation and emissions of sulphur dioxide and black carbon, reducing air pollution should let surface radiation increase. Reverting back to 1960s radiation levels could yield a 12–13% increase in China’s solar electricity generation. → Sweerts, Pfenninger, Yang, Folini, van der Zwaan and Wild (2019), Nature Energy.

Open code and data

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. I am a member of the Open Energy Modelling Initiative, which promotes openness and transparency in energy system modelling, and of the Open Power System Data project, which provides a free and open data platform for power system modelling.
