"The sum of all outputs must equal the input."
Reason: energy is conserved. In an energy transfer diagram you account for every form of energy produced from the input so total outputs = total input. The other statements are not generally true: mechanical input and output need not be equal (energy can convert to other forms), heat need not be the largest output, and electrical energy can be either an input or an output depending on the system.
