Here is some info on an energy improvement program through USDA Rural Development. Below is a snippet from the link below on how funds can be used. Loan guarantees on loans up to 75% of total eligible project costs, grants for up to 50% of total eligible costs, or a combined grant/loan guarantee funding up to 75% of eligible costs. Unfortunately, deadline is September 30th, so if you are interested, it would need to be a quick process.

 

How may the funds be used?

Funds may be used for the purchase and installation of renewable energy systems, such as:

  • Biomass (for example: biodiesel and ethanol, anaerobic digesters, and solid fuels).
  • Geothermal for electric generation or direct use.
  • Hydropower below 30 megawatts.
  • Hydrogen.
  • Small and large wind generation.
  • Small and large solar generation.
  • Ocean (tidal, current, thermal) generation.

Funds may also be used for the purchase, installation and construction of energy efficiency improvements, such as:

  • High efficiency heating, ventilation and air conditioning systems (HVAC).
  • Insulation.
  • Lighting.
  • Cooling or refrigeration units.
  • Doors and windows.
  • Electric, solar or gravity pumps for sprinkler pivots.
  • Switching from a diesel to electric irrigation motor.
  • Replacement of energy-inefficient equipment.

Energy Efficiency Improvement applications must contain an Energy Audit, or Energy Assessment (depending on Total Project Costs) that complies with Appendix A to RD Instructions 4280-B

Agricultural producers may also use guaranteed loan funds to install energy efficient equipment and systems for agricultural production or processing.
