Demand for energy resources is rising globally but supply can be insecure, which may lead to conflict.
Global demand for energy is increasing rapidly due to population growth, economic development, and rising living standards, particularly in NEEs like China and India. However, energy supply is often insecure because resources are unevenly distributed, finite, or subject to political instability. Energy insecurity occurs when a country cannot meet its energy needs reliably or affordably. This mismatch between rising demand and insecure supply can lead to conflict. Conflicts may arise over the control of energy resources, such as disputes over oil fields, or the transportation of energy, like pipelines crossing international borders. Geopolitical tensions often occur in the Middle East due to its vast oil reserves, affecting global supply.
Areas of surplus (security) and deficit (insecurity):
Energy security means having uninterrupted availability of energy at an affordable price. Areas of energy surplus produce more energy than they consume, leading to energy security. Regions like Russia and the Middle East have abundant fossil fuel reserves and export energy for economic gain. Conversely, areas of energy deficit consume more energy than they produce, resulting in energy insecurity. Regions such as Western Europe must rely on imports to meet their needs. This reliance makes them vulnerable to price fluctuations and political instability in exporting countries. Understanding the global distribution of surplus and deficit areas is crucial for analysing international energy trade and geopolitical relationships.
global distribution of energy consumption and supply
The global distribution of energy supply and consumption is highly uneven. Energy supply depends on physical factors, such as fossil fuel reserves like oil in the Middle East, and human factors, such as the capital to exploit them. Energy consumption is closely linked to economic development. High-income countries like the USA consume vast amounts of energy for industry and transport. Conversely, low-income countries consume much less per capita due to limited infrastructure. Newly emerging economies like India are seeing rapid increases in consumption as they industrialise. This mismatch between where energy is produced and consumed drives global trade and creates energy insecurity for nations relying heavily on imports.
reasons for increasing energy consumption: economic development, rising population, technology
Global energy consumption is increasing rapidly due to economic development, rising population, and technology. As countries develop economically, particularly newly emerging economies like China, industrialisation and improved living standards drive up demand for energy to power factories, transport, and appliances. Simultaneously, the global population is growing, meaning more people require energy for basic needs like heating and lighting. Furthermore, advancements in technology have led to a proliferation of electronic devices and energy-intensive systems. Even in high-income countries with slow population growth, the constant adoption of new technologies ensures that per capita energy demand remains consistently high.
factors affecting energy supply: physical factors, cost of exploitation and production, technology and political factors.
Energy supply is influenced by physical, economic, technological, and political factors. Physical factors include the natural availability of fossil fuels or suitable conditions for renewables, such as high solar insolation or strong winds. The cost of exploitation and production determines economic viability; extracting oil from deep-water reserves is much more expensive than onshore drilling. Technology plays a crucial role, as advancements like hydraulic fracturing have unlocked previously inaccessible shale gas reserves. Finally, political factors, including government policies and conflicts, can disrupt or enhance supply. For example, subsidies can promote renewables, while geopolitical tensions can restrict oil exports, directly impacting global energy security.
Impacts of energy insecurity – exploration of difficult and environmentally sensitive areas, economic and environmental costs, food production, industrial output, potential for conflict where demand exceeds supply.
Energy insecurity occurs when a country cannot meet its energy needs reliably, leading to severe impacts. To secure supply, nations may explore difficult and environmentally sensitive areas, such as the Arctic, increasing the risk of ecological disasters. This incurs high economic and environmental costs. Energy shortages directly affect food production, as modern agriculture relies heavily on fuel for machinery and natural gas for fertilisers. Industrial output also declines when factories face power cuts or high energy prices, slowing economic growth. Furthermore, when demand exceeds supply, the potential for conflict rises, as seen in geopolitical disputes over oil-rich regions or transboundary pipelines, threatening global stability.
Different strategies can be used to increase energy supply.
To meet growing global demand, countries must employ different strategies to increase their energy supply. These strategies fall into developing renewable sources, exploiting non-renewable reserves, and improving infrastructure. For example, a nation might invest in large-scale solar farms to harness renewable energy, reducing reliance on imported fuels. Alternatively, they might develop new technologies to extract previously inaccessible fossil fuels, such as hydraulic fracturing for shale gas. Nuclear power is another strategy, offering high energy output. Learners should review case studies of different countries to understand how they build a mixed energy portfolio, balancing energy security, economic costs, and environmental impacts.
Overview of strategies to increase energy supply:
This overview requires students to understand the broad range of strategies available to increase energy supply globally. Strategies include the development of renewable energy sources like biomass, wind, hydro, tidal, geothermal, and solar power. It also covers the continued extraction of non-renewable fossil fuels and the use of nuclear power. A key aspect is the exploitation of new resources in challenging environments, such as deep-water drilling, made possible by technological advancements. Learners should create categorised lists of these strategies and evaluate their potential to boost energy availability, noting how the shift towards renewable energy ensures long-term sustainability while managing immediate needs.
renewable (biomass, wind, hydro, tidal, geothermal, wave and solar) and non- renewable (fossil fuels and nuclear power) sources of energy
Energy sources are classified as renewable or non-renewable. Renewable sources replenish naturally and will not run out. These include biomass (burning organic matter), wind (turbines driven by air flow), hydro (water falling through dams), tidal (barrages capturing tidal movements), geothermal (heat from the Earth's crust), wave (harnessing ocean surface energy), and solar (photovoltaic cells capturing sunlight). Non-renewable sources are finite and will eventually deplete. These consist of fossil fuels (coal, oil, and natural gas) and nuclear power (energy from uranium fission). Understanding these distinctions is vital for evaluating future energy security and environmental impacts.
an example to show how the extraction of a fossil fuel has both advantages and disadvantages.
The extraction of fossil fuels, such as coal, oil, or natural gas, presents complex economic and environmental trade-offs. Using a specific example, such as natural gas extraction in the Amazon or coal mining in Svalbard, students must evaluate both the advantages and disadvantages. Advantages typically include job creation, increased local incomes, tax revenues for governments, and improved energy security. Disadvantages often involve severe environmental degradation, such as habitat destruction, water pollution, and the release of greenhouse gases, alongside social conflicts with indigenous populations or local communities. A balanced evaluation requires specific locational details and a clear comparison of these conflicting impacts.
Moving towards a sustainable resource future:
This section introduces the overarching concept of transitioning to long-term viability in how we generate and consume power. Students must understand that current reliance on finite resources cannot continue indefinitely without severe environmental and economic consequences. The focus shifts towards strategies that balance current needs with those of future generations. This involves exploring both large-scale shifts in national energy mixes and smaller-scale changes in consumption patterns, setting the context for specific conservation and efficiency methods.
individual energy use and carbon footprints. Energy conservation: designing homes, workplaces and transport for sustainability, demand reduction, use of technology to increase efficiency in the use of fossil fuels
Reducing our carbon footprint requires action at multiple scales. Individuals can lower energy use through daily choices like turning down thermostats. Energy conservation involves designing sustainable homes with solar panels and insulation, and workplaces with smart lighting. Transport sustainability includes promoting electric vehicles and improving public transit to reduce demand. Furthermore, technology increases fossil fuel efficiency, such as using combined heat and power (CHP) plants or combined cycle gas turbines (CCGT), which generate electricity efficiently; CHP also captures waste heat for useful heating, increasing the total useful energy obtained from the fuel.
an example of a local renewable energy scheme in an LIC or NEE to provide sustainable supplies of energy.
Students must study a specific example of a local renewable energy scheme in a Low Income Country (LIC) or Newly Emerging Economy (NEE). A common example is a micro-hydro plant in rural Nepal, which uses the flow of local rivers to generate electricity for off-grid communities. This provides a sustainable supply of energy because it relies on a renewable resource (water), has low environmental impact, and is managed by the local community. It improves living standards by powering lights for education, machinery for local businesses, and reducing reliance on polluting biomass fuels like wood, thereby protecting local forests and improving indoor air quality.
