The 20 questions

  1. What does a turbine turn to make electricity?

    • A generator
    • A water filter
    • A battery
    • A glass lens
  2. Which of these is a renewable energy source?

    • Crude oil
    • Sunlight
    • Coal
    • Natural gas
  3. Coal, natural gas and nuclear power first heat water to make what, before the turbine spins?

    • Salt water
    • Hot ash
    • Steam
    • Compressed air
  4. Which energy source spins a turbine directly, without first making steam?

    • Coal
    • Nuclear
    • Wind
    • Natural gas
  5. Which definition matches the term 'energy mix'?

    • The shares of different sources a country uses to make its electricity
    • Energy from a source that nature refills faster than we use it
    • Meeting today's needs without using up resources for the future
    • A fuel made from dead plants and animals over millions of years
  6. What must the slices of an energy-mix pie chart add up to?

    • It changes each year
    • 50 percent
    • 200 percent
    • 100 percent
  7. Which of these is a fossil fuel?

    • Wind power
    • Hydroelectric power
    • Natural gas
    • Solar power
  8. Why is nuclear power described as low-carbon?

    • It captures carbon dioxide from the air and stores it underground
    • It is powered by moving water, so it adds no pollution to rivers
    • It burns wood chips that are replanted quickly to absorb the gas
    • It makes electricity without burning a fuel, so it releases little carbon dioxide
  9. Wind provides 28 percent and solar 5 percent of a country's mix. What is their combined renewable share?

    • 43 percent
    • 38 percent
    • 23 percent
    • 33 percent
  10. In the UK mix (gas 33%, wind 28%, nuclear 14%, solar 5%, other 20%), what is the share from gas plus nuclear?

    • 61 percent
    • 33 percent
    • 52 percent
    • 47 percent
  11. Country X gets coal 40%, hydro 25%, gas 15%, wind 12% and solar 8%. What is its renewable share?

    • 45 percent
    • 37 percent
    • 55 percent
    • 25 percent
  12. Using Country X (coal 40%, hydro 25%, gas 15%, wind 12%, solar 8%), what share comes from fossil fuels?

    • 75 percent
    • 55 percent
    • 40 percent
    • 63 percent
  13. In Country X's mix (coal 40%, hydro 25%, gas 15%, wind 12%, solar 8%), which source gives the most electricity?

    • Coal
    • Gas
    • Hydro
    • Wind
  14. In Country X's mix (coal 40%, hydro 25%, gas 15%, wind 12%, solar 8%), which source gives the least electricity?

    • Solar
    • Wind
    • Hydro
    • Gas
  15. A wind farm and a coal station are compared. Which statement is correct?

    • Both are non-renewable, so neither one releases any carbon dioxide into the air
    • The coal station is renewable and low-carbon, while the wind farm is non-renewable and high-carbon
    • The wind farm is renewable and low-carbon; the coal station is non-renewable and high-carbon
    • Both are renewable, but only the coal station is high-carbon when it is switched on
  16. A country's mix is 60% fossil fuels and 40% renewables. Which conclusion is best?

    • It is fully sustainable because 40 percent of its power is renewable
    • It is partly sustainable but still relies heavily on fossil fuels
    • It is entirely low-carbon and needs no change to its mix
    • It is not renewable at all because it uses some fossil fuels
  17. Which change would make an energy mix more sustainable?

    • Keeping fossil fuels because they are cheap to burn today
    • Storing more nuclear fuel in deep rock for many decades
    • Using more renewable sources that nature refills faster than we use them
    • Burning more non-renewable sources that never produce carbon
  18. Why does a bigger renewable slice make a country more sustainable?

    • Renewables do not run out and release little carbon, so future needs are protected
    • Renewables remove the need for any turbines or generators, so power is produced without them at all
    • Renewables make steam faster, so the turbine spins more quickly
    • Renewables are cheaper to burn than coal in every single year
  19. Why is nuclear power described as non-renewable even though it is low-carbon?

    • Uranium is used up and cannot be replaced quickly, so it will eventually run out
    • It only works when the wind blows across its large fuel stores
    • It produces a large amount of carbon dioxide during its operation
    • It requires coal to heat the water before the turbine can spin
  20. Which single change would make Country X's mix more sustainable?

    • Increase the amount of gas burned to heat water faster
    • Add more coal stations to lower the share of gas
    • Close all hydro dams to save water for drinking
    • Replace some coal power with more wind and solar power
