Energy productivity in agriculture
Summary
• Some background on energy in agriculture
• The NSW Farmers energy innovation program and opportunities on farm
• Strategic issues surrounding farm energy productive and regional energy security

Key message
• Australia must align water and energy policy
• Water efficient irrigation is more energy intensive
• Most pumping is diesel powered
• Electricity is more efficient
• How can irrigators obtain electricity at lower cost?
Agricultural energy statistics
• Very limited data available in Australia
• NSW farms consume an estimated 24 petajoules energy per annum
• Est cost $900 million per annum
• Farms typically at ends of distribution networks (electricity, gas, liquid fuel)
• Higher prices and lower reliability and quality than other sectors

Improving the efficiency of tractors, mobile equipment and pumping:Optimising tyre pressure and ballasting: Savings ~$15,000 p.a. (3%)Adaptive Driving and fuel use monitoring: Savings ~$10,000 p.a. (2%)Low load pump and pumping control: Savings ~$30,000 p.a. (5%)
Generate their ownElectricity generation to offset purchases from the grid:
Solar PV system of 5 kW near house: Savings ~$1,500 p.a. (3%)
Total savings: $64,500
Broadacre farms
• Pastoral and cropping. Around 36,000 SMEs, 95% of the 38,000 commercial farms in NSW.
• Energy second or third highest expense, typically exceeding 5% of the cost of production.
• Diesel for vehicles and irrigation pumping generally the biggest cost

Farm energy innovation program
• Funded by Federal department of industry
• Working with farmers across all sectors
• Key themes:
• Energy planning
• Energy purchasing
• Efficient farm vehicles
• Energy in irrigation
• Energy in intensive facilities
• Renewable energy
Energy Planning
• Identify major energy demands
• Perform farm energy audit
• Create farm energy plan
