Abstract
Political decarbonisation commitments and outcompeting renewable electricity costs are disrupting energy systems. This foresight study prepares stakeholders for this dynamic, reactive change by examining visions that constitute a probable, plausible and possible component of future energy systems. Visions were extrapolated through an expert review of energy technologies and Australian case studies.
‘Probable–Abundant’ envisages a high penetration of solar and wind with increased value of balancing services: batteries, pumped hydro and transmission. This vision is exemplified by the South Australian grid, where variable and distributed sources lead generation.

Abstract
There is a growing interest in interactive technologies that support remembering by considering functional, experiential, and emotional support to their users. Design driven research benefits from an understanding of how people experience autobiographical remembering. We present a phenomenological study in which twenty-two adults were interviewed using the repertory grid technique; we aimed at soliciting personal constructs that characterize people’s remembered experiences. Inductive coding revealed that 77,8% of identified constructs could be reliably coded in five categories referring to contentment, confidence/unease, social interactions, reflection, and intensity. These results align with earlier classifications of personal constructs and models of human emotion. The categorization derived from this study provides an empirically founded characterization of the design space of technologies for supporting remembering. We discuss its potential value as a tool for evaluating interactive systems in relation to personal and social memory talk, and outline future improvements.

Abstract
Interactive devices can support personal remembering to benefit well-being. These designs require insight into what brings the past to mind, and how people relate to such cues. Prior work focused on mementos in the home; instead, this paper presents a diary and interview study of involuntary memory cueing in everyday life. Data was collected from fifteen adult individuals, using sentence completion diaries, combined with debriefing interviews. Qualitative analysis of the data showed that these participants were relying on everyday physical objects like food items for cueing memories during everyday life, locations and (repeated) activities, while digital items and photos were shown to be less frequent stimulants. Meaningful relations to memory cues can be partially explained from a memory cueing perspective. We discuss how design for remembering can benefit from our insights, through careful trade-offs in timing, exposure to cues, and supporting a process of personal attachment with items invoking memories.
