Abstract
Electrification and sustainable energy uses are increasing in Papua New Guinea (PNG) over the last few decades. The bulk of PNG’s population (85%) lives in isolated and dispersed villages in the rural areas. Most of these isolated and dispersed areas are still yet to be connected to an electricity supply. Papua New Guinea (PNG) is richly endowed with natural resources, but exploitation has been hampered by rugged terrain, land tenure issues, and the high cost of developing infrastructure. The study is focused on mapping of enriched renewable energy zones of the entire country. Different variables related to renewable, like surface albedo index, earth skin temperature, solar insolation incident, and wind speed are used for this purpose. Three interpolation approaches, like inverse distance weighted averaging, thin-plate smoothing splines, and kriging, are evaluated to interpolate all variables. Rating and weight sum overlay operation is applied to derive potential renewable energy zones in this equatorial country. Results show that potential renewable energy distribution is high in Papua New Guinea on the March and September equinoxes. Yearly average distribution of renewable energy source variables is significantly higher in most areas of Manus, New Ireland, North Solomon, West New Britain, Northern, Central and Milne Bay; a larger portion of East New Britain; the northern part of West and East Sepik, Central, Morobe and eastern part of Madang province. The potential renewable energy distribution data can help to establish sustainable energy production in the country.

Summary
Energy, which is originated from natural resources and is constantly replenished, is called as renewable energyHow to cite this paper: Samanta, S. and Aiau, S.S. (2015) Spatial Analysis of Renewable Energy in Papua New Guinea through Remote Sensing and GIS. According to the report from Renewable Energy Policy Network for the 21st Century, 19 percent of global energy consumption and 22 percent of electricity generation are contributed from renewable sources in 2012 and 2013, respectively [2]. These sources are traditional biomass (9%), heat energy from non-biomass (4.2%), hydroelectricity (3.8%) and electricity from wind, solar, geothermal, and biomass (2%). Government of Papua New Guinea has requested the support of the World Bank to conduct awareness about wind, small hydro, solar and biomass energy resources and implementation of sufficient sustainable, renewable power generation [7]
