The Fraunhofer ISE REMod study from February 2020 embeds societal aspects via four scenario definitions, two of which attempt to variously capture resistance to change in the private realm and resistance to new infrastructure. The study is reviewed elsewhere on this forum under the title: REMod pathways study from Fraunhofer ISE, Germany.
The impact of restricting the solution space as indicated may lead to zero‑carbon energy systems several times more expensive than one in which society is fully engaged. The results are specific to Germany and the study mostly examines 95% not 100% decarbonization. Notwithstanding, broadly similar outcomes can be expected to apply under full decarbonization.
