Diese Open-Access-Publikation untersucht die Akzeptanz der sächsischen Bevölkerung gegenüber Energie- und Rohstoffvorhaben sowie die Eignung von Kommunikationsmaßnahmen zur Verbesserung des Akzeptanzniveaus. Die Bürger:innen werden erstmals repräsentativ zu ihrer (In-)Akzeptanz gegenüber Anlagearten befragt. Dabei wird nachgewiesen, dass die Akzeptanz bei lokalen Projekten immer geringer ist als soziopolitisch. Bei den erneuerbaren Energieumwandlungsanlagen ist die Akzeptanz gegenüber Wasserkraft- und Solaranlagen am höchsten, gegenüber Biomasseanlagen am geringsten. Fossile Energieumwandlungsanlagen sind weniger akzeptiert und Tage- und Untertagebaue werden am schlechtesten bewertet. Eine vergleichende Befragung der Unternehmensvertreter:innen des Energie- und Rohstoffsektors ergibt eine Dissonanz der von ihnen angenommenen zur erfassten (In-)Akzeptanz der Bevölkerung: Das Akzeptanzniveau ist unabhängig von der Art des Vorhabens geringer, als es die Unternehmensvertreter:innen annehmen.Die Erkenntnisse werden genutzt, um eine Webapplikation zu entwickeln, die es insbesondere kleinen und mittleren Unternehmen ermöglicht, zur Akzeptanzsteigerung geeignete Kommunikationsmaßnahmen auszuwählen.
