Hartmut Bossel

Bossel and co-author Florentin Krause are credited with coining the term Energiewende, used to describe the change in German energy policy from 2010 onwards, in 1980.

After returning to Germany in 1972, Bossel worked at the Fraunhofer Institute for Systems and Innovation Research (ISI) in Karlsruhe and from 1978 at the Institute of Systems Analysis and Forecasting (ISP Eduard Pestel) in Hannover. In 1979, he was appointed a professor at the University of Kassel where he held the chair of Environmental Systems Analysis and was the director of the Scientific Center for Environmental Systems Research and Environmental Systems Analysis Group. He was a member of the Balaton Group from its inception. Bossel completed several research sabbaticals abroad, including in the US, France, the former Yugoslavia, the Soviet Union, China, Malaysia, Indonesia, and New Zealand.

Bossel graduated from the Technische Universität Darmstadt in 1961 with a diploma in mechanical engineering (aeronautical sciences). He worked at the Northrop Corporation in Los Angeles until 1963. He was an assistant professor at the University of California, Berkeley, where he was awarded a PhD in engineering (aeronautical sciences) in 1967. From 1967 to 1972, he was a professor of mechanical engineering at the University of California, Santa Barbara.
