Energy-Efficient Lighting for the Farm
Purdue University Extension conducts energy audits for farmers in Indiana, Ohio, Kentucky, Illinois, and Michigan. The audits, which cost from $125 to $350, often cut farmers' energy costs by 20 to 40% by evaluating various parts of the farm operations, including lighting, heating, irrigation systems and grain-drying equipment. Audits can also address the specific needs of dairy farm operations, livestock confinement systems, greenhouse growing facilities, and aquaculture systems. The cost of an audit, and the cost of energy-efficient upgrades, can often be offset by grants offered through the USDA Rural Development's Rural Energy for America Program (REAP) or utility incentives, Purdue staff point out.
