The Universal Journal of Renewable Energy covers activity and development in the field of innovative developments in all kinds of renewable energy resources, like Wind, Solar, Bioenergy, Geothermal, Hydrogen, Hydropower and Ocean. Research in solar thermal energy, biomass, biofuel, photovoltaic technology, wind energy, material science technology, geothermal, wave and tide, mini hydro power, hydrogen production technology, ocean energy, energy conversion in buildings, energy management, economic and any renewable energy research and applications for industry, electricity, buildings and transport is included. Contributions can be either analytical, experimental or numerical, covering all aspects of renewable energy resources and applications. So, the papers published should present innovative analytical and numerical methods and novel experimental methods, as well as non-linear methods and results, which should be far beyond the current "state of art".
