2003-2006: Bottom 5 States in USDA-REAP energy efficiency projects.

2011: Top 5 States in USDA-REAP energy efficiency projects.

2010: Most improved energy efficient State. Up to #17, from #27 in 2009 (ACEEE – 10/20/11).

Spent $91.5 M in energy efficiency promotion programs with a projected savings of 410M KWh.

2010: MI Farm Energy Audit Program generated 7.3% of projected State saving at 0.1% of the cost.

A Farm Energy Audit is an essential management tool in

developing a comprehensive energy plan for your farm or rural

business.

It can pinpoint areas for reducing energy costs and energy use.

It helps prioritize implementation projects based on energy

efficiency improvements, payback period, capital outlay or

implementation duration and complexity.

A farm energy audit can also improve operational efficiency as

well as identify potential areas for renewable energy application.

Certified Farm Energy Audits are required for participation is

State, Federal and Utility energy efficiency programs.

What is a Farm Energy Audit?

Expectations On Our Energy Audits

An energy audit is an important management tool. However,

implementation of the recommended ECM’s to save energy or

increase productivity is the ultimate goal.

It integrates mgmt.'s preferences and uses a “whole enterprise”

approach in developing ECM’s or operational adjustments.

An energy audit must be conducted on-site by the certified auditor.

Remote auditing via surveys/questionnaires or third party

representatives (despite training) does not adequately capture the

management and operational/situational uniqueness inherent in all enterprises.

We strive to develop energy audits that attain tier II level standards based on the ASABE and ANSI standards for farm energy audits.

Integration of Federal, State and Utility funding options. Auditor and farmer feedback.

53 dairy farms, milking herd size 35 to 3200 averaging 254 cows with a potential energy efficiency savings of 34% or $7,084 annually.

Page 16: On-Farm Energy Audits

Milking herd size from 35 to 3200 averaging 254 cows with a potential energy efficiency savings of 34% or $7,084 annually. Average milk production per cow - 24,703 pounds/cow/yr. (18% greater than the 2010 USDA average)

The top six categories represented 89% of all energy consumed on the audited farms. The were milk cooling, water heating, lighting, manure handling, vacuum pumps, and ventilation.

Over half of the farms audited had recommendations to conserve energy in lighting, milk cooling, water heating, and vacuum pumps.
