Abstract

In India, a transition from a primarily fossil fuel–based energy system to a predominantly renewable energy system must include harnessing of winds on a large scale in combination with other renewable energies. In order to achieve energy sustainability, it is imperative that there is detailed knowledge and understanding of the potential for harnessing wind energy. Here, we present the latest detailed assessment of potential for utilization of wind energy in India with predominant technologies that are being deployed and commercially available. The assessment, for the non-Himalayan regions, using a geographic information system–based method with National Centers for Environmental Prediction–National Center for Atmospheric Research Reanalysis data and measured wind speeds has been done. The method has been revalidated with actual measurements at 97 locations. It has been found that there is enough technically and economically viable wind energy potential to meet a major portion of current and future energy requirements in India. The total onshore and offshore potential for wind energy utilization in India is of the order of 2161–5900 GW depending on the land considerations, micro-siting and type of technology deployed.
