Modern civilization is reliant on energy as a resource to power infrastructure, cook food, and heat homes. Myriad ways exist to harness this energy from various fuel sources, each with their own benefits and disadvantages. There is a growing demand for improved technologies in energy generation, storage, conversion, and transmission, and this demand propels research forward. MDPI journals in the cluster of Energy and Fuels are designed to accommodate the influx of research on energy and different types of fuels, including popular alternatives like wind and solar power. The most established journal in the cluster is Energies (IF: 3.2), developed in 2008 as a generalized outlet for all forms of energy research. Subsequent journals serve as more specialized outlets for authors to choose from.

The 11 participating journals are as follows:

• Energies (ISSN: 1996-1073) publishes papers on scientific research, technology development, engineering policy, and management studies related to the general field of energy, from technological problems in energy supply, conversion, dispatch, and final use to the thermodynamics of the physical and chemical processes behind such technologies. Energies is led by its Editor-in-Chief, Prof. Dr. Enrico Sciubba (University Niccolò Cusano, Italy);
• Batteries (ISSN: 2313-0105) covers all topics related to batteries and electrical energy storage systems. All electrochemical systems—such as lithium-ion; lead–acid; nickel metal hydride; metal–air; and next-generation batteries, supercapacitors, or fuel cells—are of interest. Papers can be related to applications—for example, portable, electric vehicle, stationary, or photovoltaic systems—or they can be independent of an application. Batteries is led by its Editor-in-Chief, Prof. Dr. Karim Zaghib (Concordia University, Canada);
• Hydrogen (ISSN: 2673-4141) provides an advanced forum for studies related to chemical, physical, and engineering developments in hydrogen science and technology.

• Biomass (ISSN: 2673-8783) covers all aspects of bioenergy, biorefining for materials and/or energy, and the circular use of biogenic carbon in the form of biomass, focusing on chemical, biochemical, and engineering routes of biomass conversion and harnessing. The journal addresses biomass, biowaste, residues, and byproduct conversion into added-value materials and energy in the framework of contributing towards a sustainable, resource-efficient, and eco-friendly economy. Biomass is led by its Editor-in-Chief, Dr. Dimitris P. Makris (University of Thessaly, Greece);
• Electricity (ISSN: 2673-4826) covers studies related to all aspects of electrical engineering. It publishes reviews, traditional research papers, and short communications, as well as Special Issues on particular subjects. The aim of Electricity is to encourage scientists to publish their experimental and theoretical results in as much detail as desired. Electricity is led by its Editor-in-Chief, Prof. Dr. Andreas Sumper (Universitat Politecnica de Catalunya, Spain);
• Wind (ISSN: 2674-032X) focuses on scientific research in wind-related fields, including concept development, design tools, engineering technologies, energy markets, economics, policies, social and environment impacts, and ecology aspects. Wind is led by its Editor-in-Chief, Prof. Dr. Horia Hangan (Ontario Tech University, Canada);
• Fuels (ISSN: 2673-3994) is a peer-reviewed, open access journal that publishes original research, review articles, and communications on all areas of fuel science and technology, in a timely manner. The aim of the journal is to provide a platform for scientists and engineers all over the world to share, promote, and disseminate their research innovations in the field of fuel characterization, processing, and technology. Fuels is led by its Editor-in-Chief, Prof. Dr. Badie Morsi (University of Pittsburgh, USA);
• Gases (ISSN: 2673-5628) is an international and interdisciplinary peer-reviewed open access journal of gas science and engineering, published quarterly online by MDPI. Gases covers the field of applied science and engineering advances in natural gas, gas emissions, gaseous pollutants, (greenhouse) gas control, and gas sensors. Gases is led by its Editor-in-Chief, Prof. Dr. Ben J. Anthony (University of Ottawa, Ottawa, Canada);
• Solar (ISSN: 2673-9941) publishes scientific research on photovoltaics and solar thermal conversion. In addition, articles discussing solar technologies’ politics, economy, and environmental issues are also welcome. Solar was indexed by ESCI in July 2025. Solar is led by its Editor-in-Chief, Prof. Dr. Jürgen Heinz Werner (University of Stuttgart, Germany);
• Energy Storage and Applications (ESA, ISSN: 3042-4011) is an international open access journal on energy storage technologies and their applications, publishing reviews, regular research papers, and short communications. Our aim is to focus on the investigation of novel storage technologies, analytical and modeling techniques, system integration, and the operational strategies of storage systems. ESA is led by its Editor-in-Chief, Prof. Dr. Zhaoyang Dong (City University of Hong Kong, China);
• Methane (ISSN: 2674-0389) publishes novel research findings, reviews, communications, and other article types that examine all aspects of methane, its natural creation or synthesis, its use (industrial use, transportation, etc.), its impact (economic, environmental, etc.), and its recycling. Our aim is to encourage scientists to publish their experimental and theoretical results in as much detail as possible. Full experimental details must be provided so that the results can be reproduced. Methane is led by its Editor-in-Chief, Prof. Dr. Patrick Da Costa (Sorbonne Université, France).
