   In the early 1990s a competition was held among the major US manufacturers to encourage energy efficiency. [39] Current US models that are Energy Star qualified use 50% less energy than the average 1974 model used. [40] The most energy-efficient unit made in the US consumes about half a kilowatt-hour per day (equivalent to 20 W continuously). [41]

   The coefficient of performance or COP (sometimes CP or CoP) of a heat pump, refrigerator or air conditioning system is a ratio of useful heating or cooling provided to work (energy) required. [ 1 ] [ 2 ] Higher COPs equate to higher efficiency, lower energy (power) consumption and thus lower operating costs.
