This paper reviews the use of a large group process for engaging the public on energy sources and technologies with a low emission profile. Specifically reported in this paper is how the large group process supports exploring Australian society’s acceptance of energy technologies by examining the effectiveness of the process for informing knowledge and changing attitudes towards low emission energy technologies. Carbon dioxide capture and storage (CCS) is given further attention in the paper because, as a relatively unknown technology with perceived risks, it is useful to examine the effects of information provision on the way the technology is perceived. Given the large group process has proven to be a successful method for accessing and informing larger numbers of stakeholders, it is one recommended to policy makers and other researchers with an interest in low emission energy technologies.
