The Challenge of Resource Management - [Optional] - Energy (Paper 2) Flashcards

Question

How does **energy** **insecurity** impact **industry**?

Answer 1

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

Answer 2

* 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

Answer 3

Energy that will never run out.

Answer 4

Energy that will eventually run out

Answer 5

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

Answer 6

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

Answer 7

Energy that is made from natural products i.e. animal waste, plants

Answer 8

Generating energy from the wind by installing wind turbines on land or at sea

Answer 9

Energy from the sun that heats water or makes electricty by using photovoltaic cells.

Answer 10

Using water to generate energy. Usually using a dam to control the flow of water through turbines.

Answer 11

Using the changing tides to turn turbines

Answer 12

Wind blowing over water generates waves which turns turbines

Answer 13

Using the earth's heat to generate electricty. Water is pumped under ground, heated to create steam that turns tubines.

Answer 14

**+** Good for LICs as it doesn't require any compex technolgy and they have access to waste resources from farms **-** not always reliable if not managed sustainably

Answer 15

**+** do not produce harmful greenhouse gases **-** dependent on weather

Answer 16

**+** can be a cheap source of energy for LICs **-** electricty production using photovoltaic cells is expensive for amount of electricity generated

Answer 17

**+** produce large amounts of energy **-** can destroy the environment in the set up of dams and cause people to be relocated

Answer 18

**+** no harmful greenhouse gases produced **-** not a continuous supply of energy

Answer 19

**+** no harmful greenhouse gases produced **-** expensive and dependent on weather conditions

Answer 20

**+** cheap source of energy and great in tectonically active areas **-** not possible to use in all countries

Answer 21

Fuels created by decomposed dead plants and animals that have been subject to heat and pressure. They have formed over millions of years. (e.g coal, oil, gas)

Answer 22

**+** well established energy resource, relatviely cheap for large amounts of energy generated **-** harmful to the environment, running out

Answer 23

**+** only small amounts of fuel needed to make large amounts of energy **-** waste is highly radioactive. Spills can be catastrophic to the environment.

Answer 24

A naturally formed fossil fuel that has formed as a result of demoposition of sea plants and animals been subject to heat and pressure on the ocean bed.

Answer 25

Russia, Iran and Qatar.

Answer 26

A natural gas trapped within sedimentary rocks

Answer 27

* China * Argentina * USA * Mexico * South Africa

Answer 28

A process call 'fracking'

Answer 29

A mixture of water, sand and chemical is directed down through pipes into the earth, at high pressure. This releases the gas inside the rocks. This then flows out of the ground through pipes.

Answer 30

* Cleanest of the fossil fuels * Less risky to extract * Creates jobs * Less CO₂ emissions compared to other non-renewables

Answer 31

* Potentially hazardous to the environment if not handled carefully * Fracking is controversial * Expensive to set up * Contributes to global warming (CO₂ emissions)

Answer 32

**+** Creates jobs **+** Peru could make up to $34 billion in 30 years **+** Wider benefits of improved infrastructure can benefit local people

Answer 33

**-** Many indigenous tribes live in the area who may be disturbed by the development **-** Environmental damage created by pipeline e.g. landslides, pollution, deforestation **-** Knock on impacts on the environment i.e. decline in fish stocks as a result of pollution, loss of animals due to deforestation

Answer 34

Meeting the needs of the present generation without compromising the ability for future generations to meet their own needs.

Answer 35

Saving energy by reducing consumption or being more energy efficient

Answer 36

* Heating systems * Lighting * Running a vehicle * Household appliances

Answer 37

* Insulate homes * Double glazed windows * Energy efficient appliances * Energy saving lightbulbs * Cycle rather than drive a car * Install renewable energy e.g. soalr panels * Use electric cars rather than petrol

Answer 38

* Changing individual actions e.g. switching off appliances * Provide suitable and accessible public transport to reduce car use * Reducing hot water in appliances e.g. cooler washing machine settings

Answer 39

* Hybrid cars - use less petrol * Power stations switching to gas * Biofuel technology in cars * More efficient car engines

Answer 40

A micro hydro plant was installed. This diverts water away from a river, using the water to power a turbine.

Answer 41

* The community currently rely on use wood for fuel which is unsustainable and environmentally damaging * The micro hydro plant doesn't require a dam therefore doesn't cause damage during set up

Answer 42

* Energy can be used to imprve day to day life i.e. cooking * Less time is spent collecting wood for fuel

Answer 43

* More jobs have been created as a result of the reliable supply of energy * Local people are able to fix and maintain the micro hydro plant which provides employment * Cheap to set up and run
