Energy content of biofuel Energy content of biofuel The Energy content of biofuel is a description of the potential energy contained in a given biofuel, measured per unit mass of that fuel, as specific energy, or per unit of volume of the fuel, as energy density. A biofuel is a fuel, produced from living organisms. Biofuels include bioethanol, an alcohol made by fermentation—often used as a gasoline additive, and biodiesel, which is usually used as a diesel additive. Specific energy is energy per unit mass, which is used to describe the energy content of a fuel, expressed in SI units as joule per kilogram
Information Bridge: Department of Energy Scientific and Technical Information and 1954, the Energy Reorganization Act of 1974, the Department of Energy Act of 1977, and the Energy Policy Act of 2005, all call for the dissemination of scientific and technical information (STI) to the public, especially information resulting from DOE and predecessor agency research and development R&D. The Energy Policy Act of 2005 states: "The Secretary, through the Office of Scientific and Technical Information, shall maintain within the Department publicly available collections of scientific and technical information resulting from research, development, demonstration, and commercial applications activities supported by the Department." Since 1947, OSTI and its predecessor organizations have helped
