Energy is an international, multi-disciplinary journal in energy engineering and research, and a flagship journal in the Energy area. The journal aims to be a leading peer-reviewed platform and an authoritative source of information for analyses, reviews and evaluations related to energy. The journal covers research in mechanical engineering and thermal sciences, with a strong focus on thermal energy and integrated energy systems, energy planning and energy management. The journal also welcomes papers on related topics such as energy conservation, energy efficiency, biomass and bioenergy, renewable energy, energy storage, energy in buildings, and on economic and policy issues, provided such topics are within the context of the broader multi-disciplinary scope of Energy. However, any pure transfer or process level energy research may not be suitable for the scope of this journal, such as combustion, fuels, heat transfer, fluid flow, wind turbine, hydro pump, and energy resources mining etc.- We give priority to thermal energy papers and not papers with a strong focus on combustion, fuels, heat transfer, fluid flow and the like. The papers on specific fossil fuel mining techniques and methods, fuels characterization and fuels chemical treatment are not within the scope of Energy. - We give priority to integrated energy systems, energy planning and energy management and not papers with a strong focus on single technologies such as wind turbines, PV materials, solar thermal coatings, biomass chemical reactions and their related heat and mass transfer process etc. Especially for wind energy, we refer to Wind Energy and Engineering Research - the sister journal of Energy. - We give priority to sustainable energy related to green transition, we request papers based on thermal engineering, particularly fossil or decarbonized fuel-related technologies, and discuss how these technologies fit into the green transformation. Papers on mining, new designs and retrofits of fuel-fired power plants are not in the scope of the Journal.- We give priority to integrated cross-sectoral smart energy systems and not to single-sector systems with a sole focus on the electricity sector. However, electrified heating and cooling systems and heat pumps are in the scope of Energy. For papers on pure electric energy, we give priority to Smart Energy - the sister journal of Energy. - We give priority to thermal management technology for electronic devices, electric batteries, photovoltaics, data centers, and even electric power plants, not a pure heat transfer for cooling. These topics are in the scope of specialized heat transfer and refrigeration journals, and not in the scope of Energy. - We give priority to energy storage systems, especially those that can be applied at energy system level, such as electric battery and thermal battery, not to materials level research or heat exchanger level research. We are interested in energy and AI research.This journal welcomes contributions that support and advance the UN's sustainable development goals, in particular SDG 7 (Affordable and clean energy). Energy welcomes research on clean energy transition and renewable energy systems, and also energy-food-water nexus.Journal SectionsHeat Transfer and Heat PumpsEnergy Conversion and Efficiency District Heating and Cooling and CAES Energy in Buildings Solar Energy - Thermal and photovoltaicsGeothermal and Organic Rankine Cycle Thermodynamics Fuels in the Green Transition Biofuels and biomass in engines and turbines Biomass and waste incineration, gasification and conversion Energy input in crop/biofuel productionHydrogen, Fuel Cells, Energy Carriers and Storage Electricity Demand, Smart Grid and Smart Energy Systems Wind Power (Prof. Huang Diangui)Hydro Energy - Wave, Tidal and Hydro PowerEnergy and Transportation Integrated Heating, Cooling and Electricity Systems National Energy SystemsEnergy and EnvironmentEnergy Planning Tools Energy PolicyEnergy and Economy Carbo
