Tonne Of Oil Equivalent
The tonne of oil equivalent (toe) is a unit of energy defined as the amount of energy released by burning one tonne of crude oil. It is approximately 42 gigajoules or 11.630 megawatt-hours, although as different crude oils have different calorific values, the exact value is defined by convention; several slightly different definitions exist. The ''toe'' is sometimes used for large amounts of energy. Multiples of the ''toe'' are used, in particular the megatoe (Mtoe, one million toe) and the gigatoe (Gtoe, one billion toe). A smaller unit of kilogram of oil equivalent (kgoe or koe) is also sometimes used denoting 1/1000 toe. Definitions The International Energy Agency defines one '' tonne of oil equivalent'' (toe) to be equal to: *1 toe = 11.63 megawatt-hours (MWh) *1 toe = 41.868 gigajoules (GJ) *1 toe = 10 gigacalories (Gcal) – *1 toe = 39,683,207.2 British thermal units (BTU) *1 toe = 1.42857143 tonnes of coal equivalent (tce) Conversion into other units: *1 toe = 7.33 ...

Units Of Energy
Energy is defined via Mechanical work, 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 1 E-19 J, . 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 imperial units, British imperial units and United States customary units, U.S. customary units for both energy and wo ...

Gigacalorie
The calorie is a unit of energy. For historical reasons, two main definitions of "calorie" are in wide use. The large calorie, food calorie, or kilogram calorie was originally defined as the amount of heat needed to raise the temperature of one kilogram of water by one degree Celsius (or one kelvin). The small calorie or gram calorie was defined as the amount of heat needed to cause the same increase in one gram of water. Thus, 1 large calorie is equal to 1000 small calories. In nutrition and food science, the term ''calorie'' and the symbol ''cal'' almost always refers to the large unit. It is generally used in publications and package labels to express the energy value of foods in per serving or per weight, recommended dietary caloric intake, metabolic rates, etc. Some authors recommend the spelling ''Calorie'' and the symbol ''Cal'' (both with a capital C) to avoid confusion; however, this convention is often ignored. In physics and chemistry the word ''calorie'' and i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bioethanol
Ethanol (abbr. EtOH; also called ethyl alcohol, grain alcohol, drinking alcohol, or simply alcohol) is an organic compound. It is an Alcohol (chemistry), alcohol with the chemical formula . Its formula can be also written as or (an ethyl group linked to a hydroxyl group). Ethanol is a Volatility (chemistry), volatile, Combustibility and flammability, flammable, colorless liquid with a characteristic wine-like odor and pungent taste. It is a psychoactive recreational drug, the active ingredient in alcoholic drinks. Ethanol is naturally produced by the fermentation process of Carbohydrate, sugars by yeasts or via Petrochemistry, petrochemical processes such as ethylene hydration. It has medical applications as an antiseptic and disinfectant. It is used as a chemical solvent and in the Chemical synthesis, synthesis of organic compound In chemistry, organic compounds are generally any chemical compounds that contain carbon-hydrogen or carbon-carbon bonds.
