As climate targets tighten, all countries must transition toward a renewable electricity system, but conflicts about generation and infrastructure deployment impede transition progress. Although the triggers of opposition are well studied, what people want remains understudied. We survey citizen preferences for a renewable electricity future through a conjoint analysis among 4,103 individuals in Denmark, Portugal, Poland, and Germany. With our study we go beyond the Likert scale survey approach specifically seeking trade-offs and contextualized preferences for regional electricity system designs. We show the importance of identifying both the "least preferred" and "most preferred" solutions and highlighting the possibility of identifying very different systems with identical utility. Lastly, our research actively bridges the divide between social aspects and techno-economic modeling, promoting their integration. We show that the most preferred system design in all four countries is a predominantly regional one, based on rooftop solar, communally owned, and not relying on transmission expansion.
