This week the National Renewable Energy Laboratory, Washington, D.C., USA, released maps illustrating the biomass resources generated in the U.S. by county. Biomass feedstock data are analyzed both statistically and graphically using a geographic information system (GIS). 

The following feedstock categories are evaluated: crop residues, forest residues, primary and secondary mill residues, urban wood waste, methane emissions from animal manure, landfills, wastewater treatment, and industrial, institutional, and commercial organic waste (e.g. food waste).

The county-by-county map can be viewed online.
