Spatial analysis of renewable energy potential in the greater southern Appalachian mountains

This research discusses the implementation of a geographic information system (GIS) for the simultaneous discovery of multiple types of renewable energy sources. In particular, the GIS model analyzes wind, solar, and biomass potential within the greater southern Appalachian region, an area which is currently very heavily dependent on coal for electricity generation. The location and availability of biomass is specifically considered in the context of potential co-fire generation within existing coal plants, while the availability of wind and solar power are based on both resource strength and the geographic, topographic, and regulatory constraints that provide limits on their use. The model determines potential wind and solar sites within the region, and potential biomass co-fire locations, based on these input constraints and it calculates the cost and generation characteristics for each site.
