  2. Power plant efficiency - Wikipedia

    en.wikipedia.org/wiki/Power_plant_efficiency

    To express the efficiency of a generator or power plant as a percentage, invert the value if dimensionless notation or same unit are used. For example: A heat rate value of 5 gives an efficiency factor of 20%. A heat rate value of 2 kWh/kWh gives an efficiency factor of 50%. A heat rate value of 4 MJ/MJ gives an efficiency factor of 25%.

  3. Energy conversion efficiency - Wikipedia

    en.wikipedia.org/wiki/Energy_conversion_efficiency

    Efficiency of power plants, world total, 2008. 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.

    If the coal/oil/gas powered power plants were required to do the exact same thing (implying capturing 100% of the CO2 and scrubbing out the acid-rain-causing materials - and also returning slag heaps, open-cast mines, water retention dams and flattened mountains to usable land, preventing damage to water tables and earthquakes from fracking and ...

  5. Spark spread - Wikipedia

    en.wikipedia.org/wiki/Spark_spread

    A precise definition of a spark spread has to be given by the source publishing such indicators. Definitions should specify energy (electricity and fuel) prices considered (delivery point & conditions) and the plant efficiency used for the calculation. Also, any plant operating costs that may be included should be stated.

  6. Thermal power station - Wikipedia

    en.wikipedia.org/wiki/Thermal_power_station

    A thermal power station, also known as a thermal power plant, is a type of power station in which the heat energy generated from various fuel sources (e.g., coal, natural gas, nuclear fuel, etc.) is converted to electrical energy. [1]

  9. Betz's law - Wikipedia

    en.wikipedia.org/wiki/Betz's_law

    The power coefficient [9] C P (= P/P wind) is the dimensionless ratio of the extractable power P to the kinetic power P wind available in the undistributed stream. [ citation needed ] It has a maximum value C P max = 16/27 = 0.593 (or 59.3%; however, coefficients of performance are usually expressed as a decimal, not a percentage).
