Energy efficiency is based on the laws of thermodynamics; therefore, a loss of energy always occurs when one form is transformed into another.

True since some of the input energy is turned into heat energy, which is then lost in the environment. This is why input work is never equal to output work, unless the problem is set in a 'perfect world'.
