  2. Energy conversion efficiency - Wikipedia

    en.wikipedia.org/wiki/Energy_conversion_efficiency

    The electrical energy input of this cell is 1.20 times greater than the theoretical minimum so the energy efficiency is 0.83 compared to the ideal cell. A water electrolysis unit operating with a higher voltage that 1.48 V and at a temperature of 25 °C would have to have heat energy removed in order to maintain a constant temperature and the ...

  3. 5-hour Energy - Wikipedia

    en.wikipedia.org/wiki/5-hour_Energy

    A 2014 article in The New York Times reported that 5-hour Energy was lobbying state attorney generals in 30 states after being investigated for deceptive advertising. [16] The New York Times report also revealed the company made contributions totaling $280,000 to the political funds of state attorneys general "after the investigation into false ...

  4. Full load hour - Wikipedia

    en.wikipedia.org/wiki/Full_load_hour

    Full Load hour is a measure of the degree of utilisation of a technical system. [1] [2] [3] Full load hours refer to the time for which a plant would have to be operated at nominal power in order to convert the same amount of electrical work as the plant has actually converted within a defined period of time, during which breaks in operation or partial load operation can also occur.

  5. Specific energy - Wikipedia

    en.wikipedia.org/wiki/Specific_energy

    In general, proteins have lower energy densities (≈16 kJ/g) than carbohydrates (≈17 kJ/g), whereas fats provide much higher energy densities (≈38 kJ/g), [8] 2 + 1 ⁄ 4 times as much energy. Fats contain more carbon-carbon and carbon-hydrogen bonds than carbohydrates or proteins, yielding higher energy density. [ 9 ]

  6. Orders of magnitude (energy) - Wikipedia

    en.wikipedia.org/wiki/Orders_of_magnitude_(energy)

    Kinetic energy of a regulation (standard) baseball (5.1 oz / 145 g) [80] thrown at 93 mph / 150 km/h (MLB average pitch speed). [81] 1.5×10 2 - 3.6×10 2 J: Energy delivered by a biphasic external electric shock (defibrillation), usually during adult cardiopulmonary resuscitation for cardiac arrest. 3×10 2 J: Energy of a lethal dose of X-rays ...

  7. Energy intensity - Wikipedia

    en.wikipedia.org/wiki/Energy_intensity

    Energy intensity of economies (1990 to 2015): Energy intensity is an indication of how much energy is used to produce one unit of economic output. Lower ratio indicates that less energy is used to produce one unit of output. [1] Energy intensity is a measure of the energy inefficiency of an economy.

  8. Watt-hour per kilogram - Wikipedia

    en.wikipedia.org/wiki/Watt-hour_per_kilogram

    The watt, kilogram, joule, and the second are part of the International System of Units (SI). The hour is not, though it is accepted for use with the SI.Since a watt equals one joule per second and because one hour equals 3600 seconds, one watt-hour per kilogram can be expressed in SI units as 3600 joules per kilogram.

  9. Cost of electricity by source - Wikipedia

    en.wikipedia.org/wiki/Cost_of_electricity_by_source

    The following data are from the Energy Information Administration's (EIA) Annual Energy Outlook released in 2020 (AEO2020). They are in dollars per megawatt-hour (2019 USD/MWh). These figures are estimates for plants going into service in 2025, exclusive of tax credits, subsidies, or other incentives. [ 134 ]
