Remember (What comes out?): Sources give electricity: cells, batteries, solar panels, generators, dynamos, power stations. Appliances use it and change it: light (torch, tube light), heat (iron, kettle, toaster), movement (fan, mixer, drill), sound (doorbell, buzzer, speaker). Ask: what comes out when it works? That is the energy it mainly gives.
