Breakdown of electrical energy use during summer and winter at six piggeries

摘要

Energy efficiency is an important performance and sustainability indicator for the Australian pig industry because of the rise in energy costs and increased focus on greenhouse gas emissions. Wiedemann et al. (2012) showed a seven-fold variation in electricity usage across naturally-ventilated, farrow to finish piggery unit types, suggesting opportunities for improved energy efficiency. A survey of 21 piggeries showed on that on average the highest energy use component is electricity at 75% (McGahanetal. 2014). The aim of this study was to continuously monitor electricity use for a 2-weck period in summer and winter at six piggeries, five in Queensland and one in Victoria.
