  2. Building insulation material - Wikipedia

    en.wikipedia.org/wiki/Building_insulation_material

    Insulation is a barrier material to resist/reduce substance (water, vapor, etc. ) /energy (sound, heat, electric, etc.) to transfer from one side to another. Heat/ Thermal Insulation is a barrier material to resist / block / reflect the heat energy (either one or more of the Conduction, Convection or Radiation) to transfer from one side to another.

  3. British thermal unit - Wikipedia

    en.wikipedia.org/wiki/British_thermal_unit

    Energy analysts accustomed to the metric "k" ('kilo-') for 1,000 are more likely to use MBtu to represent one million, especially in documents where M represents one million in other energy or cost units, such as MW, MWh and $. [15] The unit 'therm' is used to represent 100,000 Btu. [12] A decatherm is 10 therms or one million Btu.

  4. Energy density - Wikipedia

    en.wikipedia.org/wiki/Energy_density

    The density of thermal energy contained in the core of a light-water reactor (pressurized water reactor (PWR) or boiling water reactor (BWR)) of typically 1 GW (1000 MW electrical corresponding to ≈ 3000 MW thermal) is in the range of 10 to 100 MW of thermal energy per cubic meter of cooling water depending on the location considered in the ...

  5. Tog (unit) - Wikipedia

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

    The backronym thermal overall grade is also attested by several manuacturers. [citation needed] The basic unit of insulation coefficient is the R SI, (1 m 2 ⋅K/W). 1 tog = 0.1 R SI. There is also a US clothing unit, the clo, equivalent to 0.155 R SI or 1.55 tog, described in ASTM D-1518. [3] A tog is 0.1⋅m 2 ⋅K/W.

  6. Coefficient of performance - Wikipedia

    en.wikipedia.org/wiki/Coefficient_of_performance

    For a heating system this would mean two things: Reducing the output temperature to around 30 °C (86 °F) which requires piped floor, wall or ceiling heating, or oversized water to air heaters. Increasing the input temperature (e.g. by using an oversized ground source or by access to a solar-assisted thermal bank [ 10 ] ).

  7. Renewable energy - Wikipedia

    en.wikipedia.org/wiki/Renewable_energy

    Levelized cost of energy (LCOE) is a measure of the average net present cost of electricity generation for a generating plant over its lifetime. Past costs of producing renewable energy declined significantly, [ 184 ] with 62% of total renewable power generation added in 2020 having lower costs than the cheapest new fossil fuel option.
