 Since 1985, SACE/TVEC was active in preventing the construction of a number of nuclear plants in the TVA area.Its operations have since expanded to address a variety of issues relating to energy and the environment, such as electric coal generation practices, mountaintop removal, and climate change.SACE has also been a strong advocate for the increased use of energy efficiency technologies—such as solar, wind, and clean transportation—to promote the more efficient and effective use of energy resources currently in use in the Southeastern United States.
