Rather than favoring specific technologies, the term advanced energy is technology neutral. Any technology that makes energy cleaner, safer, more secure and more efficient is considered advanced energy. Examples include electric and plug-in hybrid cars, lightweight composites for the automotive industry, natural gas fueled trucks, pollution control equipment, bio energy, high-performance buildings, more efficient industrial processes, power reliability, smart grids, combined heat and power and the latest wind, solar, and nuclear technologies. Examples of Tennessee’s advanced energy industry are scattered throughout this report to give the reader a better understanding of the breadth and depth of the advanced energy economy.
