摘要

Material and energy flows and land use in North America have shifted dramatically in the last several decades and even more dramatically over the last few centuries. As concerns mount regarding the environmental, economic, and social costs of imported energy sources; feasibility studies of energy independence are one tool for guiding energy policy decisions. This paper reviews the changes in land use, material flows, andenergy flows in South Carolina over the past 400 years; showing the shift from a near hunter gatherer society, to an export based agrarian society, to the current fossil fuel dependent society. These phases and their impacts are compared and an analysis is carried out to determine the feasibility of maintaining the current system without the input of materials or energy from outside the geographic borders of the state. Historical data is combined with geospatial data setsto determine levels and limits of energy use and availability.Results include an assessment of the feasibility of using biomass,solar thermal,and solar photovoltaic technologies to maintain the current levels of consumption.
