Energy consumed in production nurseries is recognised as a significant expenditure by growers. Independent energy audits of nurseries have recognised irrigation and heating as two of the more significant energy consumption areas that can be targeted to provide business cost savings. Growers surveyed in Queensland have reported that currently energy costs represent between 2% and 7% of turnover depending on cropping and production systems, and with energy costs predicted to continue to escalate, energy savings could have an even bigger influence on a business bottom line.
