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.
