We are going to analyze the acceptance of different energy sources in temporal development by means of representative surveys. The results are to be discussed in civil dialogues and to be framed by an advisory board. This way we can deduce how attitudes and acceptance differ and evolve and how durable attitude changes are. One of the focal points in this context is the role of extreme events such as the war in the Ukraine and the question whether such events have the potential to convince even scepticts. Core elements of the studies will be Discrete-Choice Experiments (DCE) and Multi-Criteria Decision Analysis (MCDA), with which we are going to describe scenarios that will be openly accessible.</abstract><sumDscr/></stdyInfo><method><dataColl><sources/></dataColl><anlyInfo/></method><dataAccs><notes type="DVN:TOU" level="dv">CC0 Waiver</notes><setAvail/><useStmt/></dataAccs><othrStdyMat/></stdyDscr></codeBook>
