Sustainable Energy Research (formerly Renewables: Wind, Water, and Solar) provides a multidisciplinary and international forum for research in the basic science, technologies, industrial R&D, products and system implementation that accelerate the transition to sustainable energy on a local and global scale. Sustainable Energy Research welcomes contributions on all sources of energy that support a sustainable approach to energy transformation, including renewable energy, energy efficient systems, and innovative and green systems that contribute to reducing energy poverty and the use of polluting and inefficient energy systems. While focusing primarily on basic science and technological aspects, Sustainable Energy Research considers reviews and policy issue articles on themes that affect sustainable energy technologies and their implementation. Furthermore, articles are welcome as they contribute to the achievement of the United Nations Sustainable Development Goal 7 'Affordable and Clean Energy', particularly in increasing substantially the share of renewable energy in the global energy mix, and doubling the global rate of improvement in energy efficiency. Sustainable Energy Research serves as a forum for specialists from both academic institutions, research laboratories and industries involved in R&D projects, system implementation and policy formulations in this field. Topics in scope include: Solar energy Wind energy Wave energy Geothermal energy Hydroelectricity Energy harvesting devices Hydrogen energy Low carbon energy generation Biofuels Batteries and energy storage Supercapacitors Electrocatalysis and photocatalysis Carbon capture and utilization Energy systems, processes, planning and policy Energy grids and networks Energy economics .
