Why Ukraine’s campaign against Moscow’s energy sector is working.
Why Big Tech’s energy problem might prove crucial to fighting climate change.
The NRC is already experimenting and making improvements in reducing licensing review times without changing the diligence or substance of its evaluations, and the results are promising. If the projected volume of applications materializes, the NRC will need to continue to apply the new approaches it has begun using, as well as seek out additional efficiencies. This paper lays out actionable recommendations on what NRC can do now—under existing statutory authority—to further compress schedules while preserving safety, due process, and analytical quality.
Plug-in electric vehicles (EVs) are reshaping the transportation energy landscape, providing a practical alternative to petroleum fuels for a growing number of applications. EV sales grew 55× in the past decade (2014–2024) and 6× since 2020, driven by technological progress enabled by policies to reduce transportation emissions as well as industrial plans motivated by strategic value of EVs for global competitiveness, jobs and geopolitics. In 2024, 22% of passenger cars sold globally were EVs and opportunities for EVs beyond on-road applications are growing, including solutions to electrify off-road vehicles, maritime and aviation. This Review updates and expands our 2020 assessment of the scientific literature and describes the current status and future projections of EV markets, charging infrastructures, vehicle–grid integration and supply chains in the USA. EV is the lowest-emission motorized on-road transportation option, with life-cycle emissions decreasing as electricity emissions continue to decrease. Charging infrastructure grew in line with EV adoption but providing ubiquitous reliable and convenient charging remains a challenge. EVs are reducing electricity costs in several US markets and coordinated EV charging can improve grid resilience and reduce electricity costs for all consumers. The current trajectory of technology improvement and industrial investments points to continued acceleration of EVs. Electric vehicles are increasingly adopted in the USA, with concurrent expansion of charging infrastructure and electricity demand. This Review details these trends and discusses their drivers and broader implications.
PetroStates and ElectroStates clash as fossil fuels and clean energy reshape global power, strategy, and alliances.
The Climate Finance (CliF) Vulnerability Index is designed to provide a comprehensive understanding of climate vulnerability for nation states in order to improve the targeting and provision of climate change adaptation financing.
This article provides an overview, draws insights from the taxonomies of Europe and India's neighboring countries, and highlights the need for a taxonomy in India.
Energy-economic models are increasingly being used to inform climate mitigation policies. This Comment describes three situations where models misinform policymakers and calls for more iterative, policy-orientated modelling exercises that maximize learning in the pursuit of long-term emissions reductions goals.
This analysis provides an overview of changes in production and economic outcomes in US oil and gas regions, grouping them by recent trends and examining their impact on local economies.
