Questions from this subtopic

Each one with the model answer underneath.

  1. 1

    Define energy conservation.

    Model answer

    Energy conservation is reducing the amount of energy used, either by using less of a service or by delivering it more efficiently.

  2. 2

    Give three ways a household can reduce its energy use.

    Model answer

    Insulating the loft and walls, replacing lighting and appliances with efficient models, and lowering the thermostat and heating only occupied rooms.

  3. 3

    Name two national policies used to reduce energy demand.

    Model answer

    Minimum efficiency standards for buildings and appliances, and grants or obligations for home insulation.

  4. 4

    Explain how building regulations reduce long-term demand.

    Model answer

    New homes built to a high standard need far less heating for their whole life, so the saving compounds across the entire future housing stock.

  5. 5

    Give two ways transport policy can reduce energy demand.

    Model answer

    Investment in public transport and cycling so that fewer journeys are made by car, and efficiency standards or taxes that favour lower-consumption vehicles.

  6. 6

    What is a smart meter, and how does it help?

    Model answer

    A smart meter records and displays consumption in real time, which helps households see and reduce their use and lets suppliers price by time of day.
