You need to be able to describe the distribution of
energy production.
Topic 1= Energy Security
The topic is split into 3 key questions:
1. To what extent is the world's energy
'secure' at present ?
• Energy supply, demand and security
2. What are the potential impacts of an
increasingly 'energy insecure' world?
•
The impacts of Energy Insecurity
3. What might the world's energy future be?
•

What does it mean to be energy
secure?
• To have ENERGY SECURITY means to
have access to reliable and affordable
energy sources
• E.g. Russia
• Countries that do not have this are said to
be ENERGY INSECURE
Key terms –
learn and use
Achieving Energy Security
Factors important are:
• Control over supplies
• Control over prices
• Having a variety of energy sources to call
on
• Political stability (in supply region as well
as demand region)
Energy security can be threatened by:
• Rapid increase in prices (oil 2004)
• Instability of suppliers (Georgia 2008)
• Manipulation of supply and process
• Attack on infrastructure (terrorism)
• Competition from expanding economies
e.g. China
• Environmental legislation which adds to
the costs of finding, transporting and
processing the resource
Energy security can be improved by:
• Greater energy efficiency
• Greater energy self-sufficiency
• Decentralization of energy production
• Short term stockpiles (90 days)
Energy Issues across the World
– which statement goes where?
•Rapidly growing demand; use of pollution
sources such as high sulphur coal; health
impacts; impact on global fossil fuel prices
•Reserves; questions of developing these in
the Arctic, Antarctic and other sensitive
areas
•Energy poverty; dependency on foreign
TNCs to exploit supply (Nigeria, Sudan)
•Dependency; wastefulness; lack of fossil
fuel supply (energy insecurity)
•Supply security; role of unstable regions in
fossil fuel supply; link between nuclear
power and weapons.
•Huge surplus; inefficient use; energy as a
political weapon?
