Air conditioning efficiency
Alas, air conditioners are not particularly efficient. 
Efficiency of an air conditioner 
= cooling capacity / power consumed
= (BTU/hour) / (BTU/hour) = a percentage. 
Efficiency depends upon
Temperature in room. 
Temperature outdoors. 
geometry of room (airflow)
but it is never even close to 100%! 
60% is pretty good...
