The National Renewable Energy Laboratory (NREL) routinely estimates the technical potential of specific renewable electricity generation technologies. These are technology-specific estimates of energy-generation potential based on renewable-resource availability and quality, technical-system performance, topographic limitations, environmental, and land-use constraints only. In most cases, the estimates do not consider economic or market constraints, and therefore do not represent a level of renewable generation that might actually be deployed. This report is unique in unifying assumptions and application of methods employed to generate comparable estimates across technologies, where possible, to allow cross-technology comparison. Technical potential estimates for six different renewable energy technologies were calculated by NREL, and methods and results for several other renewable technologies from previously published reports are also presented. The accompanying table summarizes the U.S. technical potential, in generation and capacity terms, of the technologies examined. The report first describes the methodology and assumptions for estimating the technical potential of each technology, and then briefly describes the resulting estimates. The results discussion includes state-level maps and tables containing available land area (square kilometers), installed capacity (GW), and electric generation (GWh) for each technology.
