A companion journal to ENERGY, the international journalSmart Energy is an international, multi-disciplinary journal with a focus on smart energy systems design, analysis, planning and modelling. The journal aims to be a leading platform and an authoritative source of information related to the green transformation of energy supply and demand systems into future smart renewable energy and sustainable solutions.The journal covers technical and energy engineering research of technologies and system designs with a focus on energy systems. Research is welcome on the role of smart energy technologies and energy infrastructures into an energy systems context such as energy conversion, energy efficiency, energy storage, electrification, power-to-heat, power-to-gas, power-to-liquids, electrofuels, district heating, district cooling and renewable energy.The journal aims at further developing the cross-sectorial approach in smart energy systems exploiting synergies between energy efficiency and use of different energy storages also considering smart electricity grids, smart thermal grids as well as smart gas grids. Research related to such technologies in renewable energy systems focusing on system re-design, transitions, renewable energy integration, analysis, energy planning, management, financing, market designs, public regulation, economics, modelling, as well as use of smart meters, data, AI and digitalization is welcome provided such topics are within the context of the broader multi-disciplinary scope of Smart Energy.We thank Storywise for providing original design of the cover image.This journal welcomes contributions that support and advance the UN's sustainable development goals, in particular SDG 7 (Affordable and clean energy)
