Questions from this subtopic

Each one with the model answer underneath.

  1. 1

    Describe the global trend in energy demand.

    Model answer

    Total demand continues to rise, with almost all the growth now coming from emerging and developing economies while demand in developed countries is broadly flat.

  2. 2

    Explain why energy demand rises with economic development.

    Model answer

    Industrialisation, transport and appliance ownership all consume energy, and each rises as incomes grow.

  3. 3

    Why has energy demand levelled off in many developed countries?

    Model answer

    Heavy industry has declined or relocated, appliances and buildings have become far more efficient, and the economy has shifted towards services.

  4. 4

    Define energy intensity.

    Model answer

    Energy intensity is the amount of energy used per unit of economic output.

  5. 5

    Why does energy intensity usually fall as a country develops further?

    Model answer

    The economy shifts from energy-hungry manufacturing towards services, and efficiency improves across industry and buildings.

  6. 6

    Give two economic factors influencing energy demand.

    Model answer

    The price of energy relative to income, and the structure of the economy between industry and services.
