  2. Emission intensity - Wikipedia

    en.wikipedia.org/wiki/Emission_intensity

    An emission intensity (also carbon intensity or C.I.) is the emission rate of a given pollutant relative to the intensity of a specific activity, or an industrial production process; for example grams of carbon dioxide released per megajoule of energy produced, or the ratio of greenhouse gas emissions produced to gross domestic product (GDP).

  3. Life-cycle greenhouse gas emissions of energy sources

    en.wikipedia.org/wiki/Life-cycle_greenhouse_gas...

    Greenhouse gas emissions are one of the environmental impacts of electricity generation. Measurement of life-cycle greenhouse gas emissions involves calculating the global warming potential (GWP) of energy sources through life-cycle assessment. These are usually sources of only electrical energy but sometimes sources of heat are evaluated. [1]

  4. Spark spread - Wikipedia

    en.wikipedia.org/wiki/Spark_spread

    Both the UK and German Dark Spread tables use a fuel efficiency factor of 35% for the coal conversion, and an energy conversion factor of 7.1 for converting tonnes/coal into MWh/electricity. In reality, each type of coal has a different energy value and each coal-fired plant has a different fuel efficiency, but 35% is accepted as a broad standard.

  5. Energy transformation - Wikipedia

    en.wikipedia.org/wiki/Energy_transformation

    Energy transformation, also known as energy conversion, is the process of changing energy from one form to another. [1] In physics , energy is a quantity that provides the capacity to perform work or moving (e.g. lifting an object) or provides heat .

  6. Townsend (unit) - Wikipedia

    en.wikipedia.org/wiki/Townsend_(unit)

    The electric field governs the energy gained between two successive collisions. Reduced electric field being a scaling factor effectively means, that increasing the electric field intensity E by some factor q has the same consequences as lowering gas density N by factor q .

  7. Energy conversion efficiency - Wikipedia

    en.wikipedia.org/wiki/Energy_conversion_efficiency

    Energy conversion efficiency (η) is the ratio between the useful output of an energy conversion machine and the input, in energy terms. The input, as well as the useful output may be chemical , electric power , mechanical work , light (radiation), or heat .

  8. Direct energy conversion - Wikipedia

    en.wikipedia.org/wiki/Direct_energy_conversion

    The conversion is based on a Traveling-Wave Direct Energy Converter (TWDEC). A gyrotron converter first guides fusion product ions as a beam into a 10-meter long microwave cavity filled with a 10-tesla magnetic field, where 155 MHz microwaves are generated and converted to a high voltage DC output through rectennas.

  9. Gas-fired power plant - Wikipedia

    en.wikipedia.org/wiki/Gas-fired_power_plant

    A cogeneration plant in Berlin Gas generates over 20% of world electricity Share of electricity production from gas. A gas-fired power plant, sometimes referred to as gas-fired power station, natural gas power plant, or methane gas power plant, is a thermal power station that burns natural gas to generate electricity.
