Energy It is equal to the energy expended (or work done) in applying a force of one newton through a distance of one metre. However energy is also expressed in many other units not part of the SI, such as ergs, calories, British Thermal Units, kilowatt-hours and kilocalories, which require a conversion factor when expressed in SI units. The SI unit of energy rate (energy per unit time) is the watt, which is a joule per second. Thus, one joule is one watt-second, and 3600 joules equal one watt-hour. The CGS energy unit is the erg and the imperial and US
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
