The 20 questions

  1. Which of the following is a primary energy source?

    • Petrol
    • Hydrogen produced from natural gas
    • Coal
    • Electricity

  2. Electricity is best described as:

    • A stock resource that is found only in mineral deposits
    • A form of energy that cannot be generated from any fuel
    • A secondary energy source generated from primary sources such as coal, gas, nuclear or wind
    • A primary energy source that is found naturally underground

  3. Which energy mix is most characteristic of a high-income country with a diverse supply?

    • Only solar power with no backup supply
    • A combination of fossil fuels, nuclear power and renewable sources
    • Only hydroelectric power in all regions
    • Only wood fuel with no other sources

  4. Acid rain is caused mainly by emissions of:

    • Chlorine from swimming pools
    • Methane from wetlands only
    • Sulphur dioxide and nitrogen oxides from burning fossil fuels
    • Carbon dioxide from respiration only

  5. The enhanced greenhouse effect refers to:

    • The natural cooling of the atmosphere at night
    • A reduction in greenhouse gas concentrations by industrial emissions
    • Increased trapping of outgoing infrared radiation by greenhouse gases from human activities
    • The reflection of sunlight from ice sheets back into space

  6. Which energy source is associated with the problem of long-lived radioactive waste?

    • Solar photovoltaic panels
    • Tidal barrages
    • Onshore wind turbines
    • Nuclear power

  7. A country's energy demand grows by 4% per year. How many years will it take for demand to double, using the rule of 70?

    • About 17.5 years
    • About 4 years
    • About 25 years
    • About 50 years

  8. Which strategy would most directly reduce demand for energy in homes?

    • Removing all draught-proofing from windows and doors, which lets heat escape faster and raises the energy needed to warm rooms
    • Improving insulation and using energy-efficient appliances
    • Leaving all appliances on standby continuously, which keeps devices ready for use and so helps households save time each day
    • Increasing the number of electric heaters per room, since more heaters in each space will reduce overall energy use across the home

  9. Which strategy would increase energy supply by using renewable sources?

    • Closing all renewable projects to save costs
    • Limiting electricity generation to fixed daily hours
    • Building more coal-fired plants with no emission controls
    • Investment in wind and solar generation capacity

  10. Which environmental impact is most typical of a major oil or gas field development?

    • Land disturbance, habitat change and risks of pollution from spills and infrastructure
    • Elimination of all carbon emissions from the site, since extraction removes the carbon stored in the rock and so cleans the local air
    • Increase in soil fertility from extraction activity, because drilling brings nutrients to the surface and improves farmland nearby
    • Creation of new permanent wetlands across the entire field, which adds habitat for waterbirds and raises local biodiversity each year

  11. Which argument best evaluates the role of transnational corporations in energy supply?

    • They always guarantee cheap and stable energy supply for all nations, because their scale ensures that prices stay low in every market
    • They operate only within national borders and never trade internationally, so their investments stay fixed where they began
    • They bring investment and technology but can create dependence and influence over national energy policy
    • They have no influence on energy markets or policy, since their operations are confined to a single stage with no role in pricing

  12. A country's coal-fired power produces 60% of its electricity. Which energy-related sustainability issue is most directly raised?

    • Lack of fossil fuel reserves in every case, because coal is becoming scarce across the world and no country holds any stock of it
    • Surplus of tidal energy with no storage needs, as tidal barrages supply more power than the grid can use at any hour of the day
    • Air pollution and greenhouse gas emissions from combustion
    • Excessive wind power generation, since turbines in the country produce so much electricity that the grid cannot absorb all of it

  13. Which argument best supports the view that energy conservation is an important part of energy security?

    • Energy conservation only affects the price of goods in shops, since saving power lowers retail costs but does not change supply at all
    • Lower demand reduces dependence on imports and lessens exposure to supply disruptions
    • Energy conservation has no effect on energy security, because demand is set by population size and cannot be changed by household choices
    • Energy conservation increases dependence on imports, since saving energy means buying more fuel from abroad to meet the same demand

  14. Which statement about the relationship between energy supply and physical geography is most accurate?

    • Hydroelectric output depends on river flow, which is shaped by climate, geology and drainage
    • Hydroelectric output is unaffected by rainfall and river volume, since turbines generate the same power whatever the flow in the river
    • Solar output is unaffected by cloud cover and latitude, because panels produce a constant amount of electricity in every climate and season
    • Wind output has no relationship with climate or topography, since turbines are placed in any location and generate the same power anywhere

  15. A country's proportion of renewable electricity rises from 20% to 50% over ten years, while total demand stays the same. What is the change in percentage points?

    • 150%
    • 30%
    • 2.5 percentage points
    • 30 percentage points

  16. Which strategy would most reduce the sustainability risks from nuclear power in the long term?

    • Discharging waste into rivers that flow to the sea, where it is diluted so thoroughly that it poses no risk to people or ecosystems
    • Secure, well-managed storage and disposal of radioactive waste
    • Ignoring waste because it decays quickly, since most radioactive material loses its hazard within a few weeks of being produced
    • Dumping waste in unprotected surface sites, which places it close to people and water supplies without any barrier or monitoring of leaks

  17. Which strategy would best address the issue of acid rain from power stations?

    • Burying sulphur-rich fuels in shallow pits, which keeps the sulphur in the ground and so prevents it from reaching the atmosphere at all
    • Moving power stations to higher wind speed zones only, since stronger winds are assumed to clear acid gases before they can fall as rain
    • Flue gas desulphurisation and the use of low-sulphur fuels
    • Increasing emissions to disperse pollution more widely, since higher stacks and greater output spread sulphur across a larger area each day

  18. Which argument best evaluates the claim that renewable energy alone can meet all future energy demand?

    • It depends on storage, grid capacity and costs, so a mix of supply and demand strategies is often needed
    • It cannot be considered at all because it is not measurable, since no reliable data exist on the output of wind and solar schemes
    • It is impossible because renewable energy never produces electricity, given that every turbine and panel fails to generate in practice
    • It is certain because renewable energy has no limitations, since every source produces steady power at all times regardless of weather

  19. Which measure would best show the success of a strategy to reduce energy consumption in a city?

    • Falling energy use per person over time, adjusted for changes in economic output
    • The number of energy advertisements on buses, counted each month along main routes and compared with the spend of each firm
    • The number of energy companies in the city, counted each year from trade registers and compared with the number of firms in other cities
    • The number of hours the city is lit at night, recorded by the council each winter and compared with the hours of darkness in each season

  20. A new oil field is developed in a region with fragile ecosystems. Which strategy would best reduce environmental impact?

    • Building roads and pipelines through the most sensitive areas to save time, since fast construction reduces the total cost of the project
    • Ignoring habitat surveys because the field is remote, since distant areas are assumed to have no wildlife or ecological value at all
    • Environmental impact assessment with mitigation such as pipeline routing away from sensitive habitats
    • Allowing unrestricted waste disposal near the field, since local dumping is cheaper and speeds up each stage of the development
