Questions from this subtopic

Each one with the model answer underneath.

  1. 1

    Define a country's energy mix.

    Model answer

    The energy mix is the combination of sources a country uses to meet its total energy demand, expressed as the share contributed by each.

  2. 2

    Name four factors that shape a country's energy mix.

    Model answer

    Its domestic resource endowment, its level of economic development, government policy and public attitudes, and the cost and availability of imports.

  3. 3

    Describe the typical energy mix of a low-income country.

    Model answer

    A large share from traditional biomass such as wood, charcoal and dung, with limited and unreliable electricity from a small grid.

  4. 4

    Give two consequences of dependence on traditional biomass.

    Model answer

    Indoor air pollution causing respiratory disease, and deforestation and time spent collecting fuel, which falls largely on women and children.

  5. 5

    What is appropriate technology?

    Model answer

    Appropriate technology is technology matched to the skills, resources and needs of the community using it, so it can be maintained and repaired locally.

  6. 6

    Give three examples of appropriate technology for rural energy.

    Model answer

    Solar home systems with a panel and battery, micro-hydro schemes on a local stream, and improved cooking stoves that burn less fuel.
