Full specification wording
Energy security: Relationship of energy supply (volume and quality) to key aspects of physical geography – climate, geology and drainage.
Physical geography dictates the volume and quality of a region's domestic energy supply.

Study notes
From the checked teaching notes for this specification point.
The idea
Physical geography dictates the volume and quality of a region's domestic energy supply. Geology determines the presence of high-quality, energy-dense fossil fuels; sedimentary basins trap oil and gas, while tectonic boundaries offer geothermal potential. Climate controls the viability of renewable supplies; high insolation levels in arid regions provide reliable solar volume, whereas consistent prevailing winds are essential for wind power. Drainage patterns directly influence hydroelectric power (HEP) capacity. A steep river gradient combined with high, reliable discharge in a large drainage basin ensures a high-volume, continuous energy supply. Understanding these physical constraints explains why energy security varies globally, as nations are bound by their natural endowments.
What earns the marks
- Explain how geological structures, such as sedimentary basins, control the volume and accessibility of fossil fuel reserves.
- Assess how climatic factors, including insolation and wind speed, determine the reliability and volume of renewable energy supplies.
- Link drainage basin characteristics, such as river discharge and gradient, to the potential volume of hydroelectric power generation.
- Evaluate the concept of energy 'quality' in relation to physical geography, such as the high energy density of geologically formed anthracite coal versus lower-quality lignite.
Common mistakes and how to put them right
Ignoring the 'quality' aspect of the specification.
Put it right: Explicitly discuss energy density or reliability alongside total volume.
Failing to link drainage to specific physical parameters.
Put it right: Refer to river discharge, velocity, and valley cross-profiles rather than just stating that water is needed for HEP.
Overlooking the role of geology in renewables.
Put it right: Geology also dictates geothermal energy potential and the availability of uranium for nuclear power.
Exam tips
- Structure essays on this topic by dedicating distinct paragraphs to climate, geology, and drainage to ensure full coverage of the specification.
- Use specific geographical examples, such as the geology of the Middle East for oil or the drainage of the Amazon basin for HEP, to illustrate physical relationships.
- Explicitly use the terms 'volume' and 'quality' when evaluating how physical geography impacts a nation's energy supply.
