  • Many countries are considering tax cuts on petrol and diesel in the wake of fuel price surges following Russia’s invasion of Ukraine. Here, the authors find that such a tax cut in the EU would increase Russian oil profits, and model the impact a cash transfer to citizens would have instead.

  • Realizing the full potential of clean cooking transitions requires an understanding of fuel stacking in which multiple fuels and stoves are used. Towards this end, Perros et al. analyse the literature on clean cooking interventions through a behavioural model and identify underlying drivers of stacking.

  • Metal–organic frameworks (MOFs) are promising candidates to store hydrogen for transportation, but less focus has been on their potential for storage in large-scale, stationary applications. Here Peng et al. perform techno-economic analysis and process modelling to evaluate the prospects of MOFs for back-up power.

  • Providing reliable, sustainable and clean energy in humanitarian contexts is increasingly important but a lack of data on settlements impedes progress. Here, Baldi et al. present a database and analytical tools for 288 refugee settlements in sub-Saharan Africa that can support renewable energy deployment decisions.

  • As renewable energy technology costs fall, there are increasing calls to remove policy support. Pahle et al. examine the impacts of such a move combined with higher interest rates in the European Union, and find that resulting higher financing could double long-term carbon prices and halve the rate of capacity deployment in the next 15 years.

  • To decarbonise the shipping sector, a deeper understanding of the suitability of carbon-neutral fuels is required. Here, the authors assess the techno-economics of a variety of energy carriers in terms of their ability to power the bulk shipping fleet in Europe.

  • Policy effort has been put into pollution reduction from both coal-fired electricity and domestic solid fuel burning in China; however, the former has attracted greater research and funding. Li and colleagues now show that the more toxic pollution from residential combustion may be responsible for greater health impacts than coal electricity.

  • Billions of people still rely on polluting fuels like wood or charcoal for cooking, which impacts health and livelihoods, despite efforts to transition to cleaner fuels. This Analysis integrates a comparison of supply- and demand-side factors that determine cooking fuel use among peri-urban households in Cameroon, Kenya and Ghana.

  • Achieving ambitious climate goals requires the development of new technologies at rapid pace. Probst et al. analyse global patent data and find that a growth period of inventions from 1995 to 2012 was followed by a decline of ~6% annually, while invention remains concentrated in just a few countries.

  • Many socioeconomic growth and low-emission energy scenarios do not consider impacts on clean cooking access and have yet to account for the COVID pandemic. Pachauri et al. now examine how clean cooking access evolves under various scenarios post COVID and find the need for policy focused on increasing access more urgent.

  • Techno-economic studies of photovoltaic solar cells recycling and reuse often do not take into account the impact of social factors. Walzberg et al. use an agent-based model to estimate the quantitative impact of behavioural choices on photovoltaic recycling efficacy.

  • Behavioural interventions can reduce energy consumption and hence carbon emissions among households. Khanna et al. compare the effectiveness of different types of monetary and non-monetary household interventions using a machine learning-assisted meta-analysis, and examine the situations where each is most useful.

  • The impact of extreme weather events driven by climate change is increasingly disrupting energy assets and services. Using operational data of nuclear reactors, Ali Ahmad identifies how disruptions in nuclear power production have increased over the years with increasing temperature anomalies, and projects future loss of output.

  • Costs of renewable energy generation have fallen rapidly in recent years, often faster than predicted. Wiser et al. undertake an expert elicitation survey to project wind power costs to 2050, finding substantial continued cost reductions, and compare back to a previous survey to understand what has changed.

  • Current battery electric vehicles cannot meet all daily travel needs on a single charge. Wei et al. use travel survey data to model charging infrastructure scenarios under a range of battery sizes to find the best suite of charging options and use of supplemental vehicles to electrify personal vehicle transport.

Using a model that accounts for building stock and transportation fleets, Isik et al. visualize emission changes in the transport sector in New York City under various electric vehicle adoption and grid decarbonization scenarios.

  • The concentration of rooftop solar photovoltaics among high-income households limits deployment and access to benefits. Here the authors find that some policy interventions and business models increased photovoltaic adoption equity in existing markets and shifted deployment to underserved communities.
