Answer: The Natural Resources Conservation Service (NRCS) has contracted with GDS Associates to create about 13 energy self-assessment tools for farms. They can be found at http://144.92.31.19/.
These calculators are still undergoing some revisions, but they are well done, under the supervision of Scott Sanford at the University of Wisconsin-Madison. They will eventually appear on the NRCS websites and I would expect them to become well-known and even standard.
Companies like EnSave have their own tools and checklists, but these tend to be proprietary.
Our publication "Farm Energy Calculators: Tools for Saving Money on the Farm" provides links to a couple dozen other calculators.
This kind of information is somewhat scattered and inconsistent, and there are important regional variations. But I hope these will be some helpful starting points.
