A

Economic development, population growth, development of technology and affluence (increase in the standard of living).

71
Q

Give four factors that affect energy supply.

A

Physical factors such as the right geology for fossil fuels, cost of exploitation and production, technology, political factors such as war and corruption.

72
Q

What is meant by the term energy security?

A

Consumers have access to the energy they need as a price that avoids volatility.

73
Q

What is meant by the term energy insecurity?

A

Energy insecurity is when consumers do not have access to the energy they need or are priced out of an energy supply.

74
Q

Give four impacts of energy insecurity.

A

Damage to environmentally sensitive areas, environmental coasts such as the release of greenhouse gases, loss of habitats, noise and visual pollution, use of valuable farm land, conflict and lower industrial output.

75
Q

Identify two types of renewable energy

A

Biomass, HEP, Wave and tidal power, geothermal power, solar power and wind power.

76
Q

How is biomass used to create renewable energy?

A

Burning material derived from living things. Burning the material produces electricity.

77
Q

How does hydroelectric power work?

A

Water is trapped in a reservoir behind a dam. As it flows through the dam it turns a turbine generating electricity.

78
Q

How does wave and tidal power produce electricity?

A

Wave and tidal power involve generating energy from the sea. A turbine is turned as water flows through it, generating electricity.

79
Q

How does geothermal energy produce electricity?

A

Geothermal energy involves uses heat within the Earth to generate electricity.

80
Q

How does solar power produce electricity?

A

It involves using solar panels installed on buildings or in fields that turn sunlight into electricity.

81
Q

How does wind power produce electricity?

A

Wind turbines convert the movement of air into electricity.

82
Q

Identify a case study for the extraction of fossil fuels.

A

Natural gas extraction - The Camisea project in Peru

83
Q

Give three advantages of the Camisea project

A

Could save Peru up to US$4 billion in energy costs. Peru could have increased income from gas exports, up to US$34 billion over 30 years. More jobs and improved infrastructure benefits local people.

84
Q

Give three disadvantages of the Camisea project

A

Deforestation to enable a pipeline construction. Developers bring diseases which local people do not have any immunity to. Clearing routes for pipelines has caused landslides and pollution of streams, harming fish.

85
Q

Identify three solutions to energy insecurity that are more sustainable.

A

Reducing carbon footprints, energy conservation and better technology.

86
Q

What is a carbon footprint?

A

The total amount of carbon a person or organisation is responsible for being emitted.

87
Q

How can we reduce carbon footprints?

A

Using less energy to reduce carbon footprint. This could also include using more public transport, waking or cycling. Also buying locally produced food will reduce food miles.

88
Q

How can we conserve energy?

A

Using energy-saving measures such as wall and loft insulation, smart meters and turning heating down. Also, local councils could promote energy conservation by creating cycle lands and introducing congestion charges.

89
Q

How can we use better technology to give us better energy security?

A

Using more energy efficient appliances, switch to electric vehicles and increasing vehicle excise duty for cars that are heavy polluters.

90
Q

Identify a case study of a local renewable energy scheme in an LIC or NEE

A

Chambamontera in Peru - a micro-hydro scheme

91
Q

Why was the micro-hydro scheme needed at Chambamontera?

A

Chambamontera is an isolated community in the Andes Mountains of Peru (a NEE). Most people are dependent on subsistence farming and small-scale coffee farming/livestock rearing. Development was limited by a lack of electricity. Nearly half of the population were surviving on just US$2 a day.

92
Q

How did the micro-hydro scheme at Chambamontera work?

A

The charity, Practical Action, supported the area to develop a micro-hydro scheme, costing US$51,000. This is how the micro-hydro scheme works: 1. A mountain stream is diverted along a man-made channel. 2. It then goes steeply downhill through a pipe into a generator room where it turns a turbine and generates electricity.

93
Q

Identify economic successes associated with the scheme.

A

Jobs created for the local people as electricity allowed the development of more businesses like a local radio station. People also got jobs working directly on the scheme and maintaining it.

94
Q

Identify environmental successes associated with the scheme.

A

More control over the river so less risk of flooding. Uses renewable energy.

95
Q

Identify social successes associated with the scheme.

A

Better healthcare. Electricity available to power fridges to keep medication and vaccines in.
