This theme explores the classification and distribution of energy resources, the physical factors determining their supply, and the drivers of energy demand. It examines the management of energy supplies, the factors influencing national energy mixes, and the challenges associated with energy extraction, transport, and use. It also addresses the role of appropriate technology in developing countries and the need for sustainable solutions to meet energy demand.
Energy mixes refer to the combination of different energy sources used to meet a country's total energy demand. This topic explores how energy mixes vary between countries at different stages of development, and how these mixes change over time. Understanding energy mixes is crucial because energy is fundamental to economic development, quality of life, and environmental sustainability. The topic links to broader themes in human geography, such as globalisation, resource security, and sustainable development.
Development is often measured by indicators like GDP per capita, HDI, or energy consumption per capita. As countries develop, their energy mixes typically shift from traditional biomass (e.g., wood, dung) to fossil fuels (coal, oil, gas) and eventually to low-carbon sources (nuclear, renewables). This transition is known as the energy transition. However, the pace and pattern of this transition vary due to factors like resource endowment, technology, government policy, and international agreements.
For WJEC A-Level Geography, this topic is part of the 'Energy Challenges and Opportunities' unit. Students must analyse case studies of different countries (e.g., China, Nigeria, Iceland) to understand how energy mixes reflect and influence development. They should also evaluate the environmental, economic, and social consequences of different energy choices, including the role of energy security and climate change mitigation.
