Public evaluation of electricity technologies and future low-carbon portfolios in Germany and the USA

Dirk Scheer; Wilfried Konrad; Oliver Scheel

BackgroundThis paper aims to create insights into peoples technology preferences in striving to achieve a low-carbon electricity generation system. The investigation seeks to analyze informed rather than mere opinion-based public preferences towards electricity technologies and portfolios against the background of climate mitigation options. In order to compare Germany with its strong renewable energy focus with a more fossil fuel- and nuclear-oriented country, the study presented replicates a research carried out in the USA in order to deliver data enabling such comparison. A special focus is on assessing attitudes and opinions towards carbon capture and storage as a low-carbon technology option.MethodsA mixed-method focus group approach has been elaborated and applied for 15 focus groups including a total of 130 participants nationwide. The approach first starts off with a traditional focus group design, i.e., discussion rounds with 8 to 10 participants led by a facilitator in order to collect qualitative data. This traditional focus group approach is extended by a quantitative survey design where participants had to fill out several closed-question questionnaires before and during the discussion rounds.ResultsMain quantitative results presented in this article consist of an electricity technology ranking and an electricity portfolio ranking. The results show considerable differences between US and German participants. While nuclear energy and the carbon capture and storage technology option are high ranking in the USA, German participants clearly favor renewable energies.ConclusionsThe comparison made clear that the stated preferences show a country bias, revealing a unique profile of technology and portfolio preferences in the USA and Germany. The policies that lie ahead of society need to find approval by stakeholders and the public at large, and therefore need to integrate acceptance profiles into communication and information activities.

Fokusgruppen im Mixed-Method-Design: Kombination einer standardisierten und qualitativen Erhebung

Dirk Scheer; Wilfried Konrad; Oliver Scheel; Frank Ulmer; Andreas Hohlt

Zur Analyse von Einstellungen und Bewertungen von Stromtechnologien und dem zukunftigen deutschen Strommix wurde ein Fokusgruppenansatz im Mixed- Method-Design entwickelt. Dieser kombiniert den qualitativen Ansatz von Gruppendiskussionen mit standardisierten Befragungen der Fokusgruppenteilnehmer. Die Vorstellung und Erlauterung dieses Ansatzes steht im Mittelpunkt des folgenden Aufsatzes, indem zunachst Anforderungen und Design beschrieben und sodann Erfahrungen bei der praktischen Anwendung berichtet werden.

Combined Natural and Social Science Approach for Regional-Scale Characterisation of CO2 Storage Formations and Brine Migration Risks (CO2BRIM)

Holger Class; Alexander Kissinger; Stefan Knopf; Wilfried Konrad; Vera Noack; Dirk Scheer

The CO2BRIM project pursues a combined technical-social sciences approach for investigating participatory modelling applied to different stages of a characterisation of potential CO2 storage formations. From the technical point of view, the project deals with two topics: The first one is concerned with an early stage site screening, where the Gravitational Number (Gr) is used as an indicator for storage efficiency dependent on the conditions found in German Middle Buntsandstein rock units. The second topic addresses the problem of large-scale salt water displacement due to the injection of CO2. Both topics are accompanied by a method called Participatory Modelling, where third parties, i.e. stakeholders with different background, are involved into the modelling process. This report gives some details about the methodological aspects of participatory modelling for the two technical topics and discusses the results for the Gr-characterisation in detail; first results and preliminary discussions from work on large-scale brine displacement are added at the end.

Partizipative Modellierung: Erkenntnisse und Erfahrungen aus einer Methodengenese

Marion Dreyer; Wilfried Konrad; Dirk Scheer

Dieser Beitrag widmet sich der partizipativen Modellierung (PM). Als solche fassen wir die Mitwirkung von gesellschaftlichen Anspruchsgruppen und Wissenstragern bei der Erstellung und/oder Nutzung konzeptioneller und computergestutzter Modelle. PM ist bisher vor allem in den Natur- und Technikwissenschaften zur Anwendung gekommen. Sie scheint aber zunehmend als ein Ansatz verstanden zu werden, bei dem Sozialwissenschaftler wichtige Aufgaben ubernehmen konnen. Dieser Beitrag, der konzeptionelle wie anwendungsorientierte Aspekte behandelt, stellt diese Aufgaben auf Basis einer Literaturanalyse heraus. Vorab wird PM als ein generischer Begriff fur eine Vielzahl konzeptioneller und praktischer Formate der Akteurseinbindung prasentiert und die transdisziplinare Nachhaltigkeitsforschung als Haupteinsatzgebiet von PM bestimmt. Nach der Erorterung der Rolle und Relevanz der Sozialwissenschaften in PM-Prozessen wird PM anhand des Forschungsprojekts CO2BRIM veranschaulicht. In diesem Projekt werden sozialwissenschaftliche Zugange zur partizipativen Modellierung in Bezug auf eine energie- und klimapolitisch relevante Technologieentwicklung erprobt. Dem Anwendungsbeispiel folgt eine Diskussion der Chancen und Herausforderungen von PM in transdisziplinaren Projekten.
