# Volker Quaschning

Volker Quaschning (born 1969) is a German engineer and professor of renewable energy systems at the Hochschule für Technik und Wirtschaft Berlin, Germany.

## Life

Quaschning studied electrical engineering at Karlsruhe Institute of Technology, then wrote his PhD on photovoltaics at the Technische Universität Berlin. After obtaining his habilitation on low-carbon power system scenarios for Germany, he worked for the German Aerospace Center in Almeria, Spain and lead research into concentrated solar power. In 2004, Quaschning was appointed professor of renewable energy systems at the Hochschule für Technik und Wirtschaft Berlin.
Quaschning is the author of several books, including the scientific textbook Regenerative Energiesysteme (Renewable energy systems), first published in 1998. In 2015, the ninth edition of this book was released. The book has been translated in English, Arabic, and Russian and a translation to the Kazakh language is in progress. According to Panos Konstantin, the book is "highly recommendable".$^{:312}$ In 2016, an updated second edition in English was published.
