Failures in power distribution grids can affect thousands of customers but understanding their causes remains elusive. Ji et al. analyse large-scale power outage data during both a hurricane and daily operations and find that local failures disproportionally affect non-local regions of grid infrastructure.

In this issue, Nature Energy takes a closer look at some of the ways in which the social sciences are addressing problems in energy and climate change.
Scholars and practitioners have advocated for greater public participation in decisions about renewable energy technologies. Nonetheless, many questions remain regarding the role of the public and the scope, purpose and openness of these decision processes.
The resilience of distribution power grids is put to the test by daily operations as well as by extreme weather events such as hurricanes. An analysis of blackout data in upstate New York now reveals that larger blackouts have a disproportionate effect on grid reliability.
Rechargeable aqueous batteries are attractive energy storage technologies owing to their low cost and high safety, but suffer from poor electrochemical performance. Now, an aqueous mild-acid-based Zn/MnO2 battery that operates via a conversion mechanism is shown to have a long-term cycling stability.
Oxygen reduction at the cathode of fuel cells typically requires a platinum-based material to catalyse the reaction, but lower-cost, more stable catalysts are sought. Now, an intrinsically conductive metal–organic framework based on cheaper elements is shown to be a durable, structurally well-defined catalyst for this reaction.
Economic agents have varying expectations on oil price fluctuations that play an important role in determining the timing and magnitude of oil price shocks. A study now shows that heterogeneous expectations should be included when modelling oil price shocks to grasp their impact on macroeconomic outcomes and energy policies.
When making decisions about energy, consumers and policymakers typically overlook moral issues, which can have profound societal consequences. This Perspective explores how ideas from justice and ethics can provide a framework to reconsider energy problems and better inform decision-making processes.
Meeting carbon emissions commitments while providing necessary energy services means reducing fossil fuel consumption. This Review presents social science insights for increasing adoption of low-carbon and low-consumption technologies and engendering practice changes among households and organizations.
Current approaches to energy systems invoke individual rational consumers, despite the fact that their decision-making cannot be simplified so readily. This Perspective explores the concept of consumers as part of a wider transition, offering a typology of the users who are shaping and enacting system change.
Rechargeable aqueous batteries are attractive owing to their relatively low cost and safety. Here the authors report an aqueous zinc/manganese oxide battery that operates via a conversion reaction mechanism and exhibits a long-term cycling stability.
There is an intensive effort in developing multi-shelled metal oxide nanostructures for lithium-ion battery applications. Now, a metal anion-adsorption mechanism, as opposed to the conventional cation adsorption on carbonaceous templates, is demonstrated in the synthesis of vanadium oxide hollow microspheres, which exhibit excellent battery performance.
Power grids often fail during extreme weather events such as hurricanes, leaving millions of customers without electricity. A large-scale analysis of the operation of power grids in an extended geographical area now reveals that such events exacerbate vulnerabilities that are obscured during normal operation.
Efficient catalysts for the oxygen-evolution reaction, especially in alkaline media, are highly desired because of their application in various energy technologies. Now, a gold-supported NiCeOx catalyst is shown to have excellent catalytic activity due to synergistic geometric and electronic effects.
