Electric cookers are one of the highest energy consuming domestic appliances, and there are several aspects that can influence the amount of energy used when preparing a meal. Appliance characteristics are shown to influence consumption, but human factors play an important role in the overall electricity usage. A user observation study was conducted among university students to understand how they use electric cookers. They were asked to perform a specific cooking task, and the electricity usage was measured. Participants' behaviours were analysed and compared with a set of energy saving techniques. Appliance characteristics that influenced how students use energy were also investigated. The results show that users performed the task in several different ways, presenting diverse energy consumption, the average being 3 times above the necessary to complete the task. This information is now informing the design of interventions to motivate people to change their behaviours whilst cooking.
电炊具是能耗最高的家用电器之一，在准备饭菜时，有几个方面会影响能源使用量。研究表明，电器特性会影响能耗，但人为因素在总体用电量中也起着重要作用。对大学生进行了一项用户观察研究，以了解他们如何使用电炊具。要求他们执行一项特定的烹饪任务，并测量用电量。分析了参与者的行为，并与一系列节能技术进行了比较。还研究了影响学生能源使用方式的电器特性。结果表明，用户以几种不同的方式执行任务，呈现出不同的能源消耗，平均能耗比完成任务所需的能耗高出3倍。这些信息现在为激励人们在烹饪时改变行为的干预措施设计提供了依据。
