9 h. ago Puerto Rico case study provides better way to plan for energy transitions

A new article published in Nature Communications offers insight into how government planners can better account for the many uncertainties that accompany the transition from fossil-fuel power systems to renewable or decarbonized systems. The paper, titled "Identifying key uncertainties in energy transitions with a Puerto Rico case study," is the work of a team from the University of Virginia including first author Kamiar Khayambashi, a Ph.D. student in the School of Engineering and Applied Science.
