Exam questions on Energy resources

  1. A fishing village on the coast of Scotland wants to produce its own electricity. The council is considering a wind farm on the hills above the village and a tidal barrage across the nearby estuary.
    Explain why the village could not rely on the wind farm alone to meet its electricity needs.2 marks
  2. A gas-fired power station in Qatar generates electricity for a nearby city. Natural gas is burned to heat water, and the steam that is produced is used to generate the electricity.
    Describe how the energy in the steam is transferred to electrical energy.2 marks
  3. Students in Mumbai investigate a model wind turbine. A fan at a fixed distance blows air at the turbine and a voltmeter shows the voltage it generates. The students predicted that more blades would always give more voltage. They tested 2, 3, 4, 6 and 8 blades and recorded 0.8 V, 1.1 V, 1.3 V, 1.2 V and 1.0 V.
    Outline a safe method for the investigation.3 marks
