    Efficiency is the measure of how efficient a process is. It is used to assess the ability of a process in avoiding waste energy, materials, money and time in doing a desirable output. It is calculated as;

    Efficiency = useful energy ouput / total energy input

    0.25 = 20 / total energy input

    total energy input = 80
