In a government report from the National Renewable Energy Laboratory demonstrates the tremendous potential for solar energy generation in Tennessee. The report estimates the technical potential of solar PV as well as other renewable power sources for the production of electrical power. It is a study of the potential based on renewable resource availability and quality, technical system performance, topographic limitations, environmental, and land-use constraints only. The study does not consider the economic, political or market constraints. In 2010, Tennessee used 103,522 GWh (103,522,000,000 kWh). The report estimates that the total solar potential including rural and urban utility-scale PV as well as roof-top solar would amount to 2,295,918 GWh.
