This theme covers the classification and distribution of energy resources, the physical factors determining their supply, and the challenges associated with managing energy demand and supply. It explores the relationship between energy mixes and development, the problems of extraction and transport, and the need for sustainable solutions through international, national, and local strategies.
Energy resources are materials that can be used to generate power, heat, or fuel. They are classified into non-renewable (fossil fuels like coal, oil, and natural gas, plus nuclear) and renewable (solar, wind, hydroelectric, tidal, geothermal, biomass). This topic is central to understanding how human societies function, as energy is essential for transport, industry, heating, and electricity. The distribution of these resources is uneven globally, leading to geopolitical tensions, economic disparities, and environmental challenges. For WJEC A-Level Geography, this topic links to themes of resource security, sustainable development, and the impacts of energy use on the physical and human environment.
The classification of energy resources is based on their rate of formation relative to consumption. Non-renewables are finite and take millions of years to form, so they are being depleted faster than they are created. Renewables are theoretically inexhaustible on a human timescale, though their availability varies by location (e.g., solar is abundant in deserts, wind in coastal areas). The distribution of energy resources is controlled by geological processes (e.g., fossil fuels in sedimentary basins, uranium in igneous rocks) and climatic factors (e.g., rainfall for hydroelectricity). This uneven distribution creates patterns of energy dependency, where some countries are energy-rich (e.g., Saudi Arabia for oil) and others are energy-poor (e.g., Japan, which imports most of its energy).
Understanding this topic is crucial for analysing contemporary issues like climate change, energy security, and the transition to low-carbon economies. It also connects to broader geographical concepts such as globalisation, inequality, and sustainability. Students should be able to evaluate the advantages and disadvantages of different energy sources, explain why certain regions have specific energy mixes, and discuss the environmental and social consequences of energy extraction and use. This knowledge forms a foundation for later topics on energy management and the geopolitics of resources.
