BiographyDr. Sailesh Samanta is working as a Senior Lecturer and Section Head of GIS section under Department of Surveying and Land Studies at The Papua New Guinea University of Technology, Papua New Guinea. He completed his PhD (2012) in Climatological modeling of Temperature and Rainfall through GIS Techniques. He has 40 peer reviewed publications in national/international journals and more than 100 citations up-to-date.Abstract Geospatial Modeling of Potential Renewable Energy in Papua New GuineaPapua New Guinea is gifted with substantial mineral and fossil carbon resources, like gold, copper, oil, natural gas etc. The fact that the bulk of energy needs of the country is resourced through natural gas and oil in electricity generation, which is the indication of imprecise, unsustainable plans and indicates a disregard towards utilization of renewable energy in electricity generation. Thus it is imperative for the country to have a paradigm shift in power generation policy as envisaged in the country’s long term development plan. With the reality of climate change looming large, with its plausible paraphernalia on the humankind, it is obvious that the rising demand for clean energy sources will swing the needle of research towards ‘the optimum harnessing of solar energy’ regime. Spatial variability of topographic elevation, slope, aspect and shadows influence the amount of insolation received at different point locations. In this scenario the solar radiation modeling is attempted in this research to map and analyse the effects of the sun over a geographic area for specific time periods. Atmospheric condition, latitudinal position, elevation, slope and aspect, sun angle, and topographic shadows are taken in account for solar energy modeling.
