An interactive web mapping tool (below) was developed to assist users in navigating the inventory by county and by category of residual biomass. The window top bar includes different tabs that users can click to navigate the inventory by biomass category. The map viewable under each tab can be zoomed and individual counties can be clicked to get county-level information. This data can be viewed in full-screen mode using the lower right-corner icon.


Energy: Terra Joule (TJ) → 1 TJ = 9.478x108 MMBtu

Mass: Giga grams (Gg) → 1 Gg = 1102.31 US tons


Initial results suggest several North Carolina rural and urban counties contain significant amounts of residual biomass that can support renewable energy projects. The results also indicate a great opportunity for mixed-source projects that leverage a mixture of residual biomasses. These projects can overcome processing limitations associated with individual biomasses and improve the logistics involved in transportation and processing. A detailed report is currently being finalized to report the data sources, methods, expert inputs and assumptions used to develop this inventory and will be available for download here.
