S6 Geography | Energy Resource Management Practice Paper 1 (Foundation)
Start from the energy mix, fossil and renewable basics, then apply the capacity factor and saving calculations to build exam vocabulary.
Attempt first, mark afterwards Allow about twenty-five minutes; name the concept (source type, site condition or formula) before writing the answer.

03 Answers and one-line notes
| # | Answer | One-line note |
|---|---|---|
| 1 | About 80 per cent, that is coal, oil and natural gas together | The share has stayed between 78 and 82 per cent for a decade, so renewables are still below one fifth. |
| 2 | One that nature replenishes at least as fast as people consume it | Solar, wind, water, geothermal and biomass all qualify; uranium is finite and is usually counted separately. |
| 3 | It is intermittent with daylight, and it needs a large land or roof area | Output falls to nearly zero at night and on cloudy days, and power density is low, so backup capacity or storage is needed. |
| 4 | A large head, a steady flow, and a valley where a dam can be built | Head drives the power and flow decides year-round output; damming also brings flooding and resettlement costs. |
| 5 | 25 per cent | 4 380 divided by (2 times 8 760 hours) equals 0.25, so it averages a quarter of its rated power. |
| 6 | About half: 0.4 to 0.45 kg against 0.9 kg of CO2 per kWh | That is why coal-to-gas switching is treated as a transitional cut, even though gas is still fossil. |
| 7 | High-level radioactive waste needs long-term storage, plus accident risk and siting opposition | Operating emissions are very low, but construction, decommissioning and waste handling all count in the life cycle. |
| 8 | Both supply interruption and price swings are controlled by outside forces | Policy therefore aims at source diversification, strategic reserves and regional grid interconnection. |
| 9 | 60 kWh | 400 times 0.15 equals 60, about 720 kWh a year, and this is demand-side management. |
| 10 | Panel manufacture and disposal pollute, and output is intermittent with low power density | Both pollution-free and full replacement are absolute claims that ignore backup capacity and material footprints. |
04 What to do after marking
- After marking, redo only the wrong items and write down which step went wrong (formula, unit, or misread number).
- Repeat the same item two days later; move to the next paper only when both attempts are correct.
- Parents only need the answer and note columns; there is no need to explain every item.
