    Does anyone know if the answer to this? Another way to look at these systems is to calculate how much removing the energy costs would reduce the price per litre of producing milk.

    Will it result in a bigger profit at the end of the year if the money were invested in more cows? Will it keep the business competitive with fluctuating milk prices?
