Critical mineral bottlenecks constrain sub-technology choices in low-carbon energy deployment.
Article in iScience, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
To meet global climate targets, countries aim to triple renewable energy capacity and rapidly deploy other low-carbon technologies by 2030. We assess the critical mineral demand required to meet these goals using a bottom-up, scenario-based approach and examine how mineral bottlenecks affect sub-technology choices. Our analysis yields three key findings. First, annual demand for critical minerals is projected to rise 6-fold, from 4.7 million tons in 2022 to 30 million tons by 2030. Second, minerals such as natural graphite, cobalt, lithium, tellurium, indium, silver, aluminum, copper, and rare earth elements may face supply constraints. Third, specific sub-technologies depend heavily on certain minerals: cadmium and tellurium shortages could limit thin-film photovoltaics; indium scarcity may hinder perovskite tandem cells; rare earths are vital for permanent-magnet wind turbines; and lithium is a key for all-solid-state batteries. Improving material efficiency and advancing mineral-efficient technologies will be essential for a resilient energy transition.
