Energy consumption depends on the rate of energy use (kW) and the duration of use (time). A small machine running 24 hours 7 days a week will consume more energy than a larger machine that is only used for a few hours a week. Typical large energy users are cold storage or cooling facilities, heating equipment and water pumps. Look out for equipment that runs during the night and on weekends – the longer time periods means more energy consumption. The energy survey as mentioned in the previous question will identify the large energy users at your facility, which may differ from other locations depending on the size of equipment and the duration of use.
