Units of energy Units of energy Because energy is defined via work, the SI unit for energy is the same as the unit of work – the joule (J), named in honor of James Prescott Joule and his experiments on the mechanical equivalent of heat. In slightly more fundamental terms, 1 joule is equal to 1 newton metre and, in terms of SI base units An energy unit that is used in atomic physics, particle physics and high energy physics is the electronvolt (eV). One eV is equivalent to 1.60217653×10 J. In spectroscopy the unit cm = 0.000123986 eV is used to represent
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
