RE resource assessment includes the identification of RE potential (candidate) areas by taking into consideration the resource (availability, concentration & extent) potential and site suitability (eligibility & constraints) assessment. Based on this assessment, RE candidate zones or areas for development are identified.

The RE types are classified into atmospheric, terrestrial and marine. Solar and wind energy are classified under atmospheric RE. Biomass, geothermal energy and hydropower are classified under terrestrial RE. Marine RE will focus on tidal in-stream and ocean thermal energy conversions.
