Solar power in Tennessee is capable of producing much of the state's electricity; however, the industry remains in early stages in the state. With 129 MW of solar power in 2015, Tennessee ranked 20th among states for installed solar capacity.

Wind power in Tennessee has most potential in East Tennessee along the North Carolina border. The state has not passed renewable portfolio standard legislation and there is just one utility-scale wind farm with 15 operating turbines and previously 3 test turbines. The Tennessee Valley Authority (TVA), based in Knoxville, imports wind-generated electricity into its service area which includes Tennessee. US Senator Lamar Alexander from Tennessee is an outspoken critic of wind power.
