Abstract

A critical need exists to investigate various renewable and solar energy technologies and examine the energy and environmental issues associated with these various technologies. The various renewable energy technologies will not be able to replace all current 102 quads (quad = 1015 BTU) of U.S. energy consumption (USCB 2007). A gross estimate of land and water resources is needed, as these resources will be required to implement the various renewable energy technologies.
