Energy prices have been volatile and increasing, and are expected to continue increasing, so energy savings can help producers reduce costs. Energy use in barns is mainly through heating, lighting, ventilation, and pumps and motors associated with other tasks, like feed transport. Ventilation fan motors represent the largest energy requirement, and improperly set temperatures can result in wasted heat from overrun ventilation. Fluorescent bulbs or T8 fixtures can significantly reduce energy requirements for lighting, as can replacing creep lights with electric heat mats. Drafts should be sealed, and insulation sufficient and upgraded if it is not. An energy audit can help identify which are most problematic, and additional ways to reduce energy use. Alternative options to reduce energy include tree windbreaks, solar walls, and heat exchangers.
