註釋 "The purpose of this analysis was to help the U.S. Department of Energy's Office of Energy Policy and Systems Analysis assess how energy transmission, storage, and distribution (TS&D) systems might perform under high-stress scenarios in which major shifts in energy demand, supply, or other uncertain factors have the potential to dramatically change the U.S. energy system by 2030. RAND researchers developed an analytical framework and associated metrics for examining vulnerabilities, opportunities, and risks to U.S. TS&D systems through 2030 under a range of uncertainties. They assessed major stresses on and opportunities in three major TS&D systems: oil and refined-oil products, electric power, and natural gas. Separately, they also considered the resilience that these systems have to short-term shocks and disruptions. This analysis was requested to support the 2015 Quadrennial Energy Review (QER). The QER, which, in its first volume, focuses on energy TS&D systems, is a federal government initiative to systematically examine energy system performance and explore options to improve that performance to address 21st-century objectives"--Publisher's description.
