Recent Trends in Renewable Energy

Global energy system must undergo a profound transformation, from fossil based fuels to renewable energy, since there is a rapid rise in energy demand which is expected to increase by 60% over the next 20 years. Renewable energy technologies offers greener alternative which is of sustainable nature and with a minimal environmental impact. As per Intergovernmental panel on climate the world must cut greenhouse gas emissions to 70 % by midcentury, and to nearly zero by 2100. Hence to address, these two issues renewable energy technologies should be advanced towards recent trends.

Advancements in solar technology like Solar PV, Solar skin, Solar tracking systems, Solar thermal fuels, Solar water purifiers etc. Offshore wind has even greater opportunities for cost reduction, Smart grid for renewable energy systems. R&D activities in the area of bio-energy including biodiesel, bioethanol, biomethanation, biomass gasification, etc. have received the tremendous attention all over the world and the government is initiating to blend ethanol with gasoline  Energy security and diversification of the energy mix is a major policy driver for renewables, in terms of the technology portfolio and geographical sources.

Despite their sustainable and efficiency, the renewable energy resources pose a number of fundamental and practical challenges that need to be addressed. The main challenges are cost of the processes, photovoltaics, wind turbines, fuel cells and biomass conversion technologies are more expensive than traditional technologies for energy. The other challenges are availability of sources like wind and solar power are not always available where and when needed. To address these issues advanced control and optimized strategies could be researched by using hybrid renewable energy system by combining different sources of energy systems.

The objective of this special issue is to highlight the most recent innovations, practical challenges encountered in renewable energy technologies and the gaps to encounter in this field. Original research articles and review papers are solicited on all aspects related to the solar, wind, hydro and bioenergy could be published in this special issue.

Potential possible topics include, but are not limited to:

  • Advanced solar PV technologies.
  • Upcoming high efficient technologies and materials in Solar Energy.
  • Energy forecasting – effective methodologies. Impediments to power evacuation and mitigation methods.
