Lecture on the energy transition

Volker Quaschning (* 1969 in Leonberg ) is an engineering scientist and professor for regenerative energy systems at the University of Applied Sciences for Technology and Economics (HTW) in Berlin .

biography

Quaschning grew up in Frankfurt am Main and studied electrical engineering at the University of Karlsruhe (TH) . He then did his doctorate at the Technical University of Berlin on the simulation of photovoltaic systems and then completed his habilitation on scenarios for a climate-friendly energy supply for Germany. From 1999 to 2004 he was project manager for solar system analysis at the German Aerospace Center (DLR) at the PSA branch in Almería , Spain, where he worked on solar thermal power plants, among other things . Since 2001 he has been running an information portal on renewable energies and climate protection on his website . Quaschning has been teaching and researching at HTW Berlin in the field of regenerative energy systems since April 2004.

He is the author of the textbook Regenerative Energiesysteme: Technologie - Calculation - Simulation , which was published for the first time in 1998 and has become the standard work on renewable energies . This monograph has since been updated and expanded and has also been translated into English , Arabic and Russian . The tenth edition was published in August 2019. According to Panos Konstantin, the book is "particularly recommendable".

His book Renewable Energies and Climate Protection , the first edition of which appeared in 2008, was translated into English in 2009. The second English edition was published in 2016 and the fifth edition of the German edition in March 2020. The book is aimed more at lay people with an interest in renewable energies and the energy transition and is, according to a review in the specialist journal Renewable Energies. The magazine "ideal for everyone who is interested in the energy transition and has not yet understood all of the interrelationships".

Quaschning is married and has children.

Positions

Volker Quaschning is of the opinion that the energy supply must be completely covered by renewable energies as quickly as possible in order to limit global warming. Using various scenarios, he comes to the conclusion that this could already be achieved in Germany by 2040. In the nuclear energy and the carbon dioxide sequestration he sees no serious alternatives. According to Quaschning, a broad mix of different renewable energies is necessary for such a restructuring of the energy industry. He sees great potential in solar energy in particular . In his opinion, photovoltaics in Germany will account for 25 to 30% of the electricity supply by 2040 at the latest.

In 2016, Quaschning published a study on the energy transition in which he examined for Germany which measures in the electricity, heating and transport sectors would be necessary in order to comply with the Paris climate protection resolutions. He also puts forward the thesis that the global energy supply would have to be converted by 2040 in such a way that it is "based entirely on renewable energies and no longer emits carbon dioxide", so that the global temperature increase still has a probability of around 50% to 1.5 ° C can be limited. The pace of the German energy transition is (as of 2016) too slow by a factor of 4 to 5. So-called sector coupling is necessary for the implementation of the energy transition . H. the extensive electrification of the heating and transport sector , whereby only wind energy and solar energy have the potential to supply Germany with regenerative energy . All other renewable energies can only perform a supplementary function.

Quaschning therefore proposes in the study a ban on oil and gas heating systems and heat-controlled CHP systems as well as the end of new registrations of gasoline and diesel cars by 2025. In addition, road freight traffic should be electrified via overhead lines and the phase-out of coal should be completed by 2030 at the latest. The electrification of the heating and transport sector would at least double the demand for electricity and in Germany could only be covered in a climate-neutral way by a very significant increase in the expansion of photovoltaic and wind power plants. The required storage requirements could be covered by a combination of decentralized battery storage and power-to-gas systems. Quaschning accuses politicians of failing to take the necessary steps to protect the climate and ultimately accepting a violation of the Paris climate protection resolutions. The study was widely received and received positively in the professional world.

With Gregor Hagedorn from the Natural History Museum Berlin , among others , Quaschning initiated the Scientists for Future movement, an association of scientists that supports the Fridays for Future movement and advocates more climate protection. In addition, Quaschning advocates an “energy revolution” in lectures and via Facebook , Twitter and YouTube .

Awards

In 2012 Quaschning was awarded a research prize and a prize for successful science communication from his then and now employer, HTW Berlin .
