The document discusses ideas for creating an advertisement targeted at teenagers aged 16-19 to encourage saving energy. The ad would use humor and sounds of electrical devices to convey the message that teenagers can make a difference by switching off lights and appliances when not in use. It aims to make teenagers think about their future and the environment by appealing to their fears and concerns about issues like global warming, as revealed in a questionnaire given to the target audience. The ad may feature scenes of light switches and a smartphone in a room, and use locations like a school to film the advertisement.
