Safeopedia Explains Net Energy Yield
Essentially, the net energy yield from an energy source refers to the gross profit gained from the source after harvest. As long as the source is capable of providing another entity with energy, it can be considered as an energy source. Net energy yield is often calculated per unit, and the most common energy sources to which this term is applied include nuclear fuel, biomass and fossil fuels.
