a. How energy resources can be classified as non-renewable (finite stocks of fossil fuel coal, oil and gas), renewable (flows of solar, wind, HEP) and recyclable (nuclear, biofuels).
Energy resources are classified into three distinct categories: non-renewable, renewable, and recyclable. Non-renewable resources are finite stocks of fossil fuels (coal, oil, and natural gas) that formed over millions of years and deplete through use because they cannot replenish on human timescales. Renewable resources are continuous flows of energy (solar, wind, and hydro-electric power/HEP) that replenish naturally and will never run out. Recyclable resources are fuels that can be reprocessed, reused, or cultivated again: nuclear power (reprocessing spent uranium fuel rods to extract further energy) and biofuels (biomass crops like sugarcane or rapeseed grown continuously for fuel). Do not confuse recyclable resources with renewables; classify finite fossil fuels as stocks, renewables as flows, and nuclear and biofuels strictly as recyclable.
b. How mining and drilling can have environmental impacts (landscape scarring, oil spills, carbon emissions, removal of forests) and the landscape impacts of renewable energy (HEP flooding, land use for wind turbines and solar panels).
Extraction and use of energy resources cause environmental consequences. Mining and drilling can scar landscapes through pits and spoil heaps, cause oil spills, release carbon emissions and remove forests cleared to reach deposits. Renewables also alter landscapes: HEP schemes flood valleys to form reservoirs, while wind turbines and solar panels occupy land. Link each impact to the extraction or energy method and to a named course example, and state the type of change: land, water, air or ecosystem. Do not treat renewables as impact-free; state the landscape cost even when the source is low-carbon.

Topic 9: 9.1 Energy resources can be classified in different ways and their extraction and use has environmental consequences exam tips
Marking Points
- Classifies coal, oil, and natural gas as non-renewable energy resources because they are finite stocks of fossil fuel that cannot be replenished on a human timescale.
- Classifies solar, wind, and hydro-electric power (HEP) as renewable energy resources because they are continuous natural flows that replenish naturally.
- Classifies nuclear power and biofuels as recyclable energy resources in accordance with the specification.
- Applies the stock (finite supply) versus flow (continuous replenishment) distinction specifically to differentiate non-renewable from renewable resources.
- Explains that recyclable resources involve reprocessing or reusing fuel (nuclear fuel reprocessing) or cultivating renewable biomass crops for fuel (biofuels).
- Names mining and drilling impacts of landscape scarring, oil spills, carbon emissions and removal of forests.
- Explains how each extraction impact arises from the activity, such as a spill from drilling or forest clearance to open a mine site.
- Identifies HEP flooding as a landscape impact of renewable energy, linked to the creation of a reservoir.
- Identifies land use for wind turbines and solar panels as a landscape impact of renewable energy.
- Distinguishes between impacts that change the landscape directly and impacts such as carbon emissions that affect the atmosphere.
Examiner Tips
- 💡Learn the three exact specification categories: non-renewable (stocks: coal, oil, gas), renewable (flows: solar, wind, HEP), and recyclable (nuclear, biofuels).
- 💡Use stock vs flow exclusively to explain why fossil fuels are non-renewable and solar/wind/HEP are renewable.
- 💡If asked about nuclear or biofuels, immediately classify them as recyclable.
- 💡Learn the four named mining and drilling impacts and the two named renewable landscape impacts as a set.
- 💡Link every impact to the activity that causes it, so the answer shows how the impact arises.
- 💡Use a named course example to support each point, and state whether the change is to land, water, air or ecosystems.
Common Mistakes
- Tries to force nuclear or biofuels into renewable or non-renewable categories; the specification explicitly defines them as recyclable.
- Applies the stock versus flow distinction to recyclable resources; nuclear utilizes mineral stock and biofuels are cultivated flows, so classify them based on recyclability/reuse rather than stock/flow.
- Labels coal, oil, or gas as renewable; they are finite fossil fuel stocks formed over millions of years.
- Describes renewable energy as having no environmental impact; correct this by stating the landscape cost of HEP flooding and of land use for turbines and panels.
- Attributes oil spills to wind power or solar panels; correct this by linking oil spills to drilling and the transport of oil.
- Classifies carbon emissions as a landscape impact; correct this by identifying them as an atmospheric impact of extracting and burning fossil fuels.
- Gives a generic impact such as pollution without naming the extraction or energy method; correct this by naming the specific method.
