Publication record and technical expertise are essential but they are not the only aspects you need to work on to become competitive for permanent positions in academia. Michael Saliba discusses how actively looking for different experiences to develop his versatility has been vital for his career progress.

Getting down to research work and writing papers are two cornerstones of an academic career. But Behnam Ghalei reflects on how exposure to different ways of thinking and development of a practical skill set have been equally important to building his independent research profile.

Funding is essential to support the early stages of an academic career but isn’t the sole determinant of success. Huilin Pan discusses how personal development and supportive teams have been crucial to her development as an independent researcher.

Building an academic career increasingly calls for greater public engagement, particularly in subjects with more societal relevance such as climate change. Leah Stokes discusses some of the difficulties she has faced in striking a balance between her academic responsibilities and her public work.

Defining your own research questions and working with a clear direction in mind is key to a successful career in academia. Evangelia Spyrou explains how following her thirst for knowledge in her specific area of interest prepared her for when research opportunities arose.

To mark the fifth anniversary of Nature Energy, past and present editors share their take on some favourite papers.

CO₂ capture and its electrochemical conversion to valorized products are energy-intense processes. Now, researchers report that judicious control of the electrode interface and reactant transport unlock a lower energy pathway allowing direct conversion of CO₂ from the captured state to CO.

While metal halide perovskite solar cells are extensively investigated in the lab their performance and degradation in real-world outdoor conditions are still poorly understood. Now, researchers propose a method to analyse field data to identify how and why the outdoor device performance changes over time.

Vehicle electrification is essential for decarbonizing road transport but there are challenges around electric vehicle adoption and infrastructure planning. By analysing real-world travel data, a new study explores the potential for different charging and supplemental vehicle strategies to allow electric vehicles to meet current driver needs.

Integrated urban energy–economy–climate scenarios can be built upon bottom-up models that simulate realistic system interactions. One such model for New York shows how electrification of the vehicle fleet and grid decarbonization can reduce carbon emissions and pollution.

Performance breakthroughs in rechargeable batteries are regularly reported in academic publications. Here the authors closely examine literature data on aluminium batteries and offer a realistic perspective on the technology.

Estimating the costs of green home improvements is not possible without accurate estimates of their impact on house prices. Now, Shen et al. use the sales data of more than 400,000 properties in the United States to determine how heat pump installations increase house prices.

Two-dimensional Ruddlesden–Popper layered metal-halide perovskites show better performance over three-dimensional versions, but are typically based on quantum wells with random width distribution. Liang et al. show that introducing molten salt spacers gives phase-pure quantum wells and improved solar cell performance.

Electrochemical conversion of CO₂ into high-value products is attractive for lowering net carbon emissions. Lee et al. present the valorization of chemisorbed CO₂ to CO in an aqueous monoethanolamine electrolyte via tailoring of the electrochemical double layer, with 72% Faradaic efficiency at 50 mA cm^–2.

The investigation of perovskite solar modules under outdoor conditions could provide insights into device operation and degradation in the field. Velilla et al. report on the potential of the ideality factor to analyse outdoor device performance evolution over time, distinguish between degradation modes and estimate the lifetime.

Two-dimensional structures introduced into perovskite solar cells improve performance yet their morphological and dimensional control remains challenging. Jang et al. devise a solid-phase approach to grow phase-pure two-dimensional perovskites over bulk perovskite, which affords greater device efficiency and stability.

As the cost of variable renewable energy generation has fallen and its proportion in power mixes has increased, discussion of its integration costs has intensified. Heptonstall and Gross systematically review the literature on these costs and asses the range of impacts it is shown to have.

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.

City-scale emission scenarios are critical for transport and energy sector policy making. 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.

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.
