How Much Energy Storage can We Afford? On the Need for a Sunflower Society, Aligning Demand with Renewable Supply.

ABSTRACT: The worsening climate crisis impels society to accelerate climate action. The attainable speed of the energy transition is ultimately limited by the available energy to build the replacing renewable infrastructures. Decarbonizing the energy system by replacing dispatchable fossil with variable renewable power requires energy storage to match supply with demand. Current storage technologies are energetically expensive to build and operate, thus the demand for storage shapes the fastest possible transition and the probability to exceed 1.5 °C heating. This study explores and quantifies the effect of demanded storage and its technological progress on the fastest possible transition constrained only by energy. The simulation results using three exemplary storage technologies show that storage substantially delays the transition and increases the probability to exceed 1.5 °C heating. Technological progress, if materialized fast, can reduce energy costs of storage; however, storage demand remains a critical driver for climate risks. Consequently, minimizing storage demand through a supply-driven power system effectively reduces climate risks-a paradigm shift towards a solar-aligned "sunflower society".

Project description:BackgroundOver 25 million US inhabitants are limited English proficient (LEP). It is unknown whether physicians fluent in non-English languages are training in geographic areas with the highest proportion of LEP people. Diversity of language ability in the physician workforce is an important complement to language assistance services for providing quality care to LEP patients.ObjectiveTo determine whether non-English language-speaking resident physicians matched in the geographic areas where language skills are needed.DesignCross-sectional study.ParticipantsPostgraduate medical training applicants to the Association of American Medical College's Electronic Residency Application Service in 2013-2014 (n = 50,766). We included data from the Graduate Medical Education Track database, mapped against American Community Survey data.InterventionsN/A.Main measuresWe assessed the geographic alignment of non-English language-speaking resident physicians relative to the distribution of the LEP-speaking population.Key resultsWhile 37% of resident physicians spoke at least one non-English language, in most cases the languages they spoke were not those in greatest need by the US LEP population. LEP speakers' potential exposure to non-English language-speaking residents varied. For Spanish, the language with the lowest national resident physician to Spanish LEP patient ratio, the ratio was most favorable in New York at 23.7/100,000 LEP population versus 5.1 in Los Angeles. For Tagalog, the group with the highest geographic mismatch, the ratio was 70.4 in New York but 0 in San Diego, San Jose, and Seattle. Among the top five LEP languages in the USA, Chinese-speaking resident physicians were the most geographically matched.ConclusionsWe found considerable misalignment of the geographic distribution of non-English language-speaking resident physicians relative to the distribution of the LEP-speaking population. Residency programs in areas of high need could consider better matching the non-English language needs of their community with the language abilities of the resident physicians they are recruiting.
