The majority of pumps in irrigated agriculture operate on diesel. Cyclical fluctuations in energy costs and improvements in pumping technology means that options around what is the most cost effective energy source for your irrigation enterprise should be assessed. This is typically determined on a $/ML basis and should be considered holistically in relation to your irrigation system. These assessments are particularly important when pumps are reaching their end of life and an opportunity exists to make a more substantial infrastructure or design change.
