  • Power usage effectiveness - Wikipedia

    Power usage effectiveness (PUE) is a ratio that describes how efficiently a computer data center uses energy; specifically, how much energy is used by the computing equipment (in contrast to cooling and other overhead).. PUE is the ratio of total amount of energy used by a computer data center facility to the energy delivered to computing equipment. PUE is the inverse of data center ...

  • Seasonal energy efficiency ratio - Wikipedia

    A similar standard is the European seasonal energy efficiency ratio (ESEER). The SEER rating of a unit is the cooling output during a typical cooling-season divided by the total electric energy input during the same period. The higher the unit's SEER rating the more energy efficient it is.

  • What is Specific Fuel Consumption? (with pictures)

    2019-11-03  Specific fuel consumption, abbreviated SFC, compares the ratio of the fuel used by an engine to a certain force such as the amount of power the engine produces.
