Global patterns of energy (Cambridge International IGCSE Geography)
Specification link
This page covers section 10.5.2 of the CIE IGCSE specification .
- 10.5.2- The global patterns of energy surplus and deficit and the importance of energy security.
Patterns of energy surplus & deficit
Spec point — The global patterns of energy surplus and deficit and the importance of energy security.
-
The global supply of energy sources is not evenly distributed
-
Production of energy sources depends on various factors
- Physical factors such as geology
- The technology opening up new opportunities for resource exploitation
- Economic factors such as the price of the resource and the cost of extraction
- Political factors such as environmental agendas and wars
-
Some places have a surplus of energy sources
-
Others have a deficit and rely on trade and imports to make up the shortfall
Energy surplus
-
Energy surplus tends to occur in countries that have:
- Large reserves of fossil fuels, such as the Middle East and Russia
- Good access to renewable energy sources – often hydroelectric or geothermal, such as Norway
- A small population compared to the energy sources available, for example, Australia
Energy deficit
-
Energy deficit tends to occur in countries that:
- Have **limited fossil fuel or renewable energy, **such as Nepal
- Have** large populations**, leading to high energy demands
- Lack the money to exploit energy resources such as countries in Sub-Saharan Africa
Importance of energy security
Spec point — The global patterns of energy surplus and deficit and the importance of energy security.
-
An energy gap is when a country cannot meet the demand for energy using its own resources
-
When countries have an energy gap, they have to import energy to meet the demand
-
Having an energy gap means that a country is not energy secure
-
To be energy secure, a country needs an:
- uninterrupted supply of energy
- affordable supply
- accessible supply

Global energy security
-
The UK has a widening energy gap and is not energy secure because:
- Renewable energy is not as efficient and so cannot replace energy from fossil fuels
- It is cheaper to import fossil fuels than it is to exploit the resources in the UK
-
The commitment of many countries to tackling climate change and reducing the use of fossil fuels has increased energy insecurity for many countries
-
There are other factors that can affect energy security:
- energy sources running out
- war/conflict
- natural hazards
- political disputes
- cost
- environmental concerns
Exam Hint When writing about global patterns of energy in your answers, it is important to make sure that you include the correct terminology, including:
- Energy surplus
- Energy deficit
- Energy security
- Energy gap
Also ensure that you can give named examples and explain why countries have an energy surplus or energy deficit.
