Agriculture production input prices are certainly unstable in a highly volatile market. Among the largest annual expenses for producers is the cost for irrigating and post-harvest treatments of their crops, controlling animal housing facilities, managing energy use in often outdated dairy systems under daily use and wear, and greenhouse production facilities using heating through Winter production and ventilation during the Summer months. To help manage energy price variability of recent times, Purdue has built a service to support making improvements and a toolbox for producers to utilize when increasing energy efficiency on-farm.

On-Farm Energy Efficiency Audit Program

Purdue Extension is equipped to assit you with an energy audit for various farm operation systems. This program involves evaluating and making calculations of your existing system efficiency, and comparing it to the proposed new systems. Producers may use this audit report to apply for the USDA REAP program, or through other incentive programs facilitated by local utility companies.  Chad Martin is a Renewable Energy Extension Specialist within the Purdue Ag & Biological Engineering Department, and is a Certified Farm Energy Auditor according to ASABE Standards.  He works closely with Dr. Klein Ileleji who is the Extension Engineer for the Purdue ABE Department.  Contact us to visit further about services available for the following sectors:

  • Grain Drying
  • Irrigation Improvements
  • Dairy Farm Operations
  • Livestock Confinement Systems
  • Greenhouse Growing Facilities
  • Aquaculture Systems
