1

What is 'energy security'?

Having a reliable, sustainable and affordable supply of energy.

2

Name some countries where energy consumption is high?

  • USA
  • Canada
  • Australia
  • UK

3

Name some regions where energy consumtion is low?

Africa

South East Asia

4

Why is Russia energy secure?

They have large reserves of natural gas and oil

 

5

Why does the Middle East region have an energy surplus?

They have large oil reserves

6

Why is Western Europe energy insecure?

  • Depends on imports
  • Not very energy effiicient

7

Why is Sub-Saharan Africa energy insecure?

  • Reliant on TNCs to extract oil and gas

8

What are the factors that affect energy supply?

  • Costs of exploitation and production
  • Physical factors
  • Political factors
  • Technology 
  • Climate

9

What physical factors affect energy supply?

  • Geology - determines what fossil fuels are under the ground
  • Abundance of potential renewable energy e.g. geothermal

10

What political factors affect energy supply?

  • Political instability 
  • Potential use of nuclear energy for political gain
  • Some governments don't subsidise some energy productions

11

Why is technology an important factor in the supply of energy? 

  • We can now use technolgy to access hard to reach resources
  • Technology makes it cheaper to access some resources

12

Why is climate an important factor in the supply of energy? 

Some areas have high amounts of solar energy or wind which makes wind turbines and solar panels an ideal choice.

13

Why is global energy consumption increasing?

- Great economic development 

- More industrial development (Asia)

14

Why does rising population affect energy consumption?

More people means more need for heating, power, vehicle fuel etc.

15

What is 'energy insecurity'?

Not having a reliable or affordable supply of energy to meet demand.

16

What are the impacts of energy insecurity?

  • price of energy increases as fossil fuels are used up
  • more environmental damage as a result of looking for more fossil fuels
  • more demand for biofuels which uses land for food production
  • indsutry relocates to access energy
  • conflict

17

How can a country increase its energy supply?

  • Try to use its own energy sources
  • Import more energy 
  • Reduce energy consumption through technology 

18

Name 2 remote regions where we can now exploit energy resources?

  1. Antarctica
  2. Arctic

19

What has made it possible to exploit resources in remote areas?

New cost effective technologies

 

20

What are the economic disadvantages of oil and gas exploitation in the Arctic?

- difficult to access therefore use of specialist equipment is expensive

- workers demand higher pay for working in a remote area

- transporting oil and gas long distances increases cost

21

What are the environmental disadvantages of oil and gas exploitation in the Arctic?

- Strict controls needed to prevent damage

- Transport can damage the environment

- Pollution from spills

22

What are 'biofuels'? 

A fuel that is made from living things e.g. plants (maize, sugar cane)

23

Why do biofuels cause food shortages?

They are grown on land which can't then be used for food production

24

What are the negatives of biofuels?

  • Uses valuable land that can be used to produce food
  • Increase food prices

25

How does energy insecurity impact industry?

  • Frequent power cuts = loss of productivity
  • Closure of some industries

26

How can energy insecurity lead to conflict?

  • Some countries own a large share of an energy resource so have power to distribute
  • They may increase cost of energy
  • They can cut off supplies for political gain
  • Hijack of oil in transit can also be an issue

27

What is 'renewable energy'?

Energy that will never run out.

28

What is 'non-renewable energy'?

Energy that will eventually run out

29

List 7 renewable energy sources 

  1. Biomass
  2. Wind power
  3. Hydropower
  4. Tidal
  5. Geothermal 
  6. Wave 
  7. Solar energy 

30

List some non-renewable energy sources 

  1. Fossil fuels (coal, oil, natural gas)
  2. Nuclear power
