   * It is not possible to introduce an efficiency factor instead of this because most activities requiring the use of energy do not have the dimension of energy.\\   * It is not possible to introduce an efficiency factor instead of this because most activities requiring the use of energy do not have the dimension of energy.\\

   * And there is no "minimum amount of energy required based on physical reasons" for providing a benefit; the contrary assumption is also a widespread misconception – the "minimum amount of energy required" is zero in most cases (or an extremely small value greater than zero).\\   * And there is no "minimum amount of energy required based on physical reasons" for providing a benefit; the contrary assumption is also a widespread misconception – the "minimum amount of energy required" is zero in most cases (or an extremely small value greater than zero).\\
