When do farmers need energy audits on their farms?

COLUMBIA, Mo.- In general, it's a good idea for farmers to look at energy use on their farm every five years and consider opportunities to reduce energy consumption, says Don Day, energy extension associate for University of Missouri Extension.

However, the need for an energy audit may vary from farm to farm, Day said. For example, if you already had an energy audit conducted on your farm, even if it was five or more years ago, it will continue to provide accurate information regarding potential energy savings until you make changes that affect energy usage.

"A new audit may also be in order if energy prices change or there is an additional energy alternative that a farmer is considering using that was not addressed initially," he said.

Changes in energy prices can alter payback periods, he added. "We have seen changes in the relative prices of energy sources over the past few years that will change what fuel a farmer might use." However, he notes, it generally doesn't pay to change the type of fuel you are using unless a piece of equipment such as a furnace or an engine needs to be replaced.

Day offers some additional recommendations to help farmers decide when they need an energy audit on their farm:

  • Enterprises added to the farming operation after an original audit was completed need to be audited because they change total energy consumption.
  • If a new farm location has been added to the farming operation, farmers should conduct an audit on the new location.
  • When replacing equipment, consider energy use of the replaced components.
  • New industry developments might necessitate a new energy audit or assessment. A good example is lighting developments (LED and CFL options) over the past few years.
  • If farmers want to apply for a grant or loan for energy updates, they may need an updated energy audit or assessment.
