The journal aims to present to the international community important results of work in the fields of renewable energy and sustainable development research to help researchers, scientists, manufacturers, institutions, world agencies, societies to keep up with new developments in theory and applications. Experimental, computational and theoretical studies are all welcomed to AJRESD. The integration of renewable energy technologies in electrical power networks and smart grids. AJRESD is a Semiannually published. The journal considers articles on the following themes, provided the link to renewable and sustainable energy is clear and thoroughly examined: Energy resources -bioresources (e.g. biomass, waste), fossil fuels (including natural gas), geothermal, hydrogen, hydropower, nuclear, marine and ocean energy, solar and wind Applications - buildings, industry and transport Utilization -batteries, conversion technologies, fuel cells, storage technologies, technical developments and technology scaling Environment -atmosphere, climate issues, meteorology, mitigation technologies (e.g. carbon capture and storage (CCS), carbon capture and utilization (CCU), solar radiation management) Techno-socio-economic aspects -health, industry, policy, political, regulatory, social (e.g. access, education, equality, equity) Systems -carbon accounting, energy-food-water nexus, energy modelling, life cycle assessment (LCA), nutrient-energy-water (NEW) nexus, smart infrastructure
