By using solar cogeneration Clover Stornetta achieved a more than 50 percent savings in energy costs used for the wastewater heating process.

Leprino Foods realized approximately $27,390 in annual energy savings by conducting a steam survey and making recommended repairs to its manufacturing facilities.

In 2000, a Wisconsin dairy completed a plant energy audit and made boiler improvements to reduce its natural gas use by 10,500 MMBtu per year, for a cost savings of $39,800 annually.

In 2009, the Marva Maid of Landover processing plant replaced old metal halide, high-pressure sodium and incandescent light fixtures with new energy efficient lighting systems and upgraded to light-emitting diode (LED) exit signs — saving 400,014 kWh per year.

Leprino Foods saved approximately $218,000 in electricity costs annually by replacing metal halide fixtures throughout the plant with fluorescent lamps and sanitary-design fluorescent fixtures that provide the same or better light coverage.

The Shamrock Farms dairy plant in Phoenix, Ariz., was able to save 80,500 kWh of electricity per year by switching from incandescent lamps to LED lighting in its vintage sign.
