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 the DOE mission are included. DOE report literature, conference papers, books, dissertations, and patents are available. The DOE Office of Scientific and Technical Information (OSTI) developed and hosts this website as a public service. The Information Bridge: DOE Scientific and Technical Information was introduced to the U.S. Department of Energy (DOE) community in 1997 and was the first electronic system to provide searchable full-text and bibliographic records of DOE-sponsored research report literature. Originally made available only to DOE and DOE contractors, Information Bridge was launched as a free public access database in April 1998. The Atomic Energy Acts of 1946
