Manufacturers may conduct a number of energy-management activities to improve the efficiency of energy use at their facilities. The four top management techniques used by the forest products industry include energy audits, electricity load controls, power factor correction or improvement, and facility lighting. The most commonly used of these is the energy audit, employed by almost 2,500 facilities in 1994. Approximately 20% of the forest products facilities reported using at least one type of energy-management activity. [MECS 1994]
