Quad (unit)
A quad is a unit of energy equal to (a short-scale quadrillion) BTU, or (1.055 exajoules or EJ) in SI units. The unit is used by the U.S. Department of Energy in discussing world and national energy budgets. The global primary energy production in 2022 was 637.8 quad, i.e., 672.9 EJ. Conversion Some common types of an energy carrier approximately equal to 1 quad are: *8,007,000,000 gallons (US) of gasoline *293,071,000,000 kWh *293.07 terawatt-hours (TWh) *33.434 gigawatt-years (GWy) *36,000,000 tonnes of coal *970,434,000,000 cubic feet of natural gas *5,996,000,000 UK gallons of diesel oil *25,200,000 tonnes of oil *252,000,000 tonnes of TNT or five times the energy of the Tsar Bomba nuclear test *12.69 tonnes of uranium-235 (with 83.14 TJ/kg) *6 seconds of sunlight reaching Earth See also * Units of energy * Orders of magnitude (energy) This list compares various energy, energies in joules (J), organized by order of magnitude.

Sankey Diagram
Sankey diagrams are a data visualisation technique or flow diagram that emphasizes flow/movement/change from one state to another or one time to another, in which the width of the arrows is proportional to the flow rate of the depicted extensive property. The arrows being connected are called nodes and the connections are called links. Sankey diagrams can also visualize the energy accounts, material flow accounts on a regional or national level, and cost breakdowns. The diagrams are often used in the visualization of material flow analysis. Sankey diagrams emphasize the major transfers or flows within a system. They help locate the most important contributions to a flow. They often show conserved quantities within defined system boundaries. History and name Sankey diagrams are named after Irish Captain Matthew Henry Phineas Riall Sankey, who used this type of diagram in 1898 in a classic figure (see diagram) showing the energy efficiency of a steam engine.

Long And Short Scales
The long and short scales are two power of 10, powers of ten number naming systems that are consistent with each other for smaller order of magnitude, numbers, but are contradictory for larger numbers. Other numbering systems, particularly in East Asia and South Asia, have large number naming that differs from both the long and short scales. Such numbering systems include the Indian numbering system and Chinese numerals, Chinese, Japanese numerals#Powers of 10, Japanese, and Korean Peninsula, Korean numerals. Much of the remainder of the world adopted either the short or long scale. Countries using the long scale include most countries in continental Europe and most that are Geographical distribution of French speakers, French-speaking, Geographical distribution of German speakers, German-speaking and Hispanophone, Spanish-speaking. Use of the short scale is found in most Anglophone, English and Arabic speaking countries, most Eurasian post-communist countries and Brazil. F ...

World Energy Supply And Consumption
World energy supply and consumption refers to the global supply of energy resources and its consumption. The system of global energy supply consists of the energy development, refinement, and trade of energy. Energy supplies may exist in various forms such as ''raw resources'' or ''more processed and refined'' forms of energy. The raw energy resources include for example coal, unprocessed oil and gas, uranium. In comparison, the refined forms of energy include for example refined oil that becomes fuel and electricity. Energy resources may be used in various different ways, depending on the specific resource (e.g. coal), and intended end use (industrial, residential, etc.). Energy production and consumption play a significant role in the global economy. It is needed in industry and global transportation. The total energy supply chain, from production to final consumption, involves many activities that cause a loss of useful energy. As of 2022, energy consumption is still ...

Energy Carrier
An energy carrier is a substance (fuel) or sometimes a phenomenon (energy system) that contains energy that can be later converted to other forms such as mechanical work or heat or to operate chemical or physical processes. Such carriers include springs, electrical batteries, capacitors, pressurized air, dammed water, hydrogen, metal energy carriers,petroleum, coal, wood, and natural gas. An energy carrier does not produce energy; it simply contains energy imbued by another system. Definition according to ISO 13600 According to ISO 13600, an energy carrier is either a substance or a phenomenon that can be used to produce mechanical work or heat or to operate chemical or physical processes. It is any system or substance that contains energy for conversion as usable energy later or somewhere else. This could be converted for use in, for example, an appliance or vehicle. Such carriers include springs, electrical batteries, capacitors, pressurized air, dammed water, hydro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gallon
The gallon is a unit of volume in British imperial units and United States customary units. The imperial gallon (imp gal) is defined as , and is or was used in the United Kingdom and its former colonies, including Ireland, Canada, Australia, New Zealand, India, South Africa, Malaysia and some Caribbean countries, while the US gallon (US gal) is defined as , and is used in the United States and some Latin American and Caribbean countries. There are four gills in a pint, two pints in a quart, and four quarts (''quarter'' gallons) in a gallon, with the imperial gill being divided into five imperial fluid ounces and the US gill being divided into four US fluid ounces: this, and a slight difference in the sizes of the imperial fluid ounce and the US fluid ounce, give different sizes for the imperial gallon and US gallon. The IEEE standard symbol for both the imperial and US gallons is gal, not to be confused with the gal (symbol: Gal), a CGS unit of acceleration. Definitions ...

Kilowatt-hour
A kilowatt-hour ( unit symbol: kW⋅h or kW h; commonly written as kWh) is a non-SI unit of energy equal to 3.6 megajoules (MJ) in SI units, which is the energy delivered by one kilowatt of power for one hour. Kilowatt-hours are a common billing unit for electrical energy supplied by electric utilities. Metric prefixes are used for multiples and submultiples of the basic unit, the watt-hour (3.6 kJ). Definition The kilowatt-hour is a composite unit of energy equal to one kilowatt (kW) multiplied by (i.e., sustained for) one hour. The International System of Units (SI) unit of energy meanwhile is the joule (symbol J). Because a watt is by definition one joule per second, and because there are 3,600 seconds in an hour, one kWh equals 3,600 kilojoules or 3.6 MJ."Half-high dots or spaces are used to express a derived unit formed from two or more other units by multiplication.", Barry N. Taylor. (2001 ed.''The International System of Units.'' (Special publicatio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tsar Bomba
The Tsar Bomba (code name: ''Ivan'' or ''Vanya''), also known by the alphanumerical designation "AN602", was a Thermonuclear weapon, thermonuclear aerial bomb, and by far the most powerful nuclear weapon ever created and tested. The Soviet physicist Andrei Sakharov oversaw the project at Arzamas-16, while the main work of design was by Sakharov, Viktor Adamsky, Yuri Babayev, , and Yuri Trutnev (scientist), Yuri Trutnev. The project was ordered by General Secretary of the Communist Party, First Secretary of the Communist Party Nikita Khrushchev in July 1961 as part of the Soviet resumption of nuclear testing after the Partial Nuclear Test Ban Treaty#Khrushchev and a moratorium: 1958–1961, Test Ban Moratorium, with the detonation timed to coincide with the 22nd Congress of the Communist Party of the Soviet Union (CPSU). Tested on 30 October 1961, the test verified new design principles for high-yield thermonuclear charges, allowing, as its final report put it, the design o ...

Uranium-235
Uranium-235 ( or U-235) is an isotope of uranium making up about 0.72% of natural uranium. Unlike the predominant isotope uranium-238, it is fissile, i.e., it can sustain a nuclear chain reaction. It is the only fissile isotope that exists in nature as a primordial nuclide. Uranium-235 has a half-life of 703.8 million years. It was discovered in 1935 by Arthur Jeffrey Dempster. Its fission cross section for slow thermal neutrons is about Barn (unit), barns. For fast neutrons it is on the order of 1 barn. Most neutron absorptions induce fission, though a minority (about 15%) result in the formation of uranium-236. Fission properties The fission of one atom of uranium-235 releases () inside the reactor. That corresponds to 19.54 TJ/mole (unit), mol, or 83.14 TJ/kg.

Units Of Energy
Energy is defined via work, so the SI unit of energy is the same as the unit of work – the joule (J), named in honour of James Prescott Joule and his experiments on the mechanical equivalent of heat. In slightly more fundamental terms, is equal to 1 newton metre and, in terms of SI base units :1\ \mathrm = 1\ \mathrm \left( \frac \right ) ^ 2 = 1\ \frac An energy unit that is used in atomic physics, particle physics, and high energy physics is the electronvolt (eV). One eV is equivalent to . In spectroscopy, the unit cm−1 ≈ is used to represent energy since energy is inversely proportional to wavelength from the equation E = h \nu = h c/\lambda . In discussions of energy production and consumption, the units barrel of oil equivalent and ton of oil equivalent are often used. British imperial / US customary units The British imperial units and U.S. customary units for both energy and work include the foot-pound force (1.3558 J), the British ...
