Energy Resources

Question 1

Give an example of how primary energy is released from a direct source.

Answer 1

Heat is released by burning coal.

Question 2

An energy source is secondary when…

Answer 2

Primary energy is converted into a different form of energ.

Question 3

Give an example of secondary energy.

Answer 3

When hear energy from coal burning is used to produce electricity.

Question 4

When is a resource renewable?

Answer 4

When it can be replenished at a similar rate to which it is used.

Question 5

Renewable energy resources are also known as what?

Answer 5

Flow resources.

Question 6

What does a flow resource mean?

Answer 6

Refers to renewable energy. It means there’s a constant energy transfer that becomes sustainable when balanced and never stops providing energy.

Question 7

List five examples of renewable energy.

Answer 7

HEP 
Tidal
Wave 
HEP
Solar

Question 8

When is a resource of energy a non renewable energy resource?

Answer 8

When it can run out and not be replaced in the foreseeable future.

Question 9

Non renewable sources are also known as what?

Answer 9

Stock resources.

Question 10

What does a stock energy resource mean?

Answer 10

A source of which there is a finite amount and once used up there will be none left.

Question 11

What are the four none renewable energy resources?

Answer 11

Coal
Nuclear
Natural gas
Oil

Question 12

What is a resource that needs careful management in order to stay renewable?

Answer 12

Critical resource.

Question 13

If the rates of what are roughly equal for an energy resource then it becomes renewable?

Answer 13

The rate the resource is being used up compared to how fast it is being replenished.

Question 14

What are two examples of critical resources?

Answer 14

Geothermal reservoirs

Wood

Question 15

Some renewable resources can be replaced, for example; fossil fuels, but explain why these are my considered renewable resources.

Answer 15

Due to the timescale involved. Fossil fuels for example take millions of years to for and are being used up much faster than they are being formed- therefore are non renewable as they cant be replaced in the foreseeable future.

Question 16

Primary every is released from what?

Answer 16

A direct source.

Question 17

Explain how using wood for an energy source can become unsustainable and how it is managed to ensure it is maintained as a renewable resource.

Answer 17

If too much is used too fast, it can distrust the natural cycle of replenishment and use the source up. Techniques like coppicing and replanting trees can ensure the wood is replaced at roughly the same rate of it being used up so it is renewable.

Question 18

Explain how the use of geothermal reservoirs for energy is a critical resource

Answer 18

Tectonic hear is used to turn water into hear at these stations. Power station is too large for the site, continually pumping water to the ground will actually cool the ground so the resource is lost- it isn’t renewable.

Question 19

Countries need energy for what four things?

Answer 19

Industry
Service
Transport
Domestic

Question 20

What is the primary energy mix?

Answer 20

The percentage of each energy source a country uses in order to supply it’s country with energy.

Question 21

Explain how the amount of oil the UK uses has changed over the years and why.

Answer 21

Since the 1970’s the UK’s oil consumption has risen for to the discovery of North Sea oil (1969) and the growing demand of transport fuel.

Question 22

Use of natural gas has increased by __________ between 1990 and 2008.

Answer 22

85%.

Question 23

Explain the changing use of coal in the UK over the years.

Answer 23

Coal use has fallen by 40% since 1990-2008 due to mine closures and the move to gas and oil as they’re less polluting.

Question 24

Coal use in the UK fell by 40% between 1990 and 2008 despite what?

Answer 24

Large reserves.

Question 25

What is the UK’s energy mix in 2008?

Answer 25

Natural gas- 40% 
Petroleum from oil- 33% 
Coal- 17%
Nuclear- 8% 
Other- 2%

Question 26

What is France’s 2004 energy mix?

Answer 26

Nuclear 44%
Petroleum from oil 33%
Natural gas 15%
Other 6%
Coal 5%

Question 27

France has limited reserved of what two resources?

Answer 27

Oil and coal.

Question 28

France has limited oil and coal reserves which means what?

Answer 28

Most of their supplies of oil and coal must be imported.

Question 29

Explain trends of oil and coal production in France.

Answer 29

Coal production is low as in France 2004- coal mining stopped fully.
Energy production from oil is high due to the high demand for transport fuel.

Question 30

Explain the trends of France gas’ use over the years.

Answer 30

Between 1990 and 2004, the amount of natural gas used has increased by over 50%- but is still lagging behind the EU avg by 24%.

Question 31

From what two courses does most of France’s renewable energy come from?

Answer 31

Hydropower

Biomass

Question 32

Explain why and how France has so much nuclear power usage.

Answer 32

Due to shortage of fossil fuels in 1970’s, it started investing in nuclear to secure energy supplies, causing 41% of 2004 energy usage in France to be from nuclear energy.

Question 33

And the _______ biggest in the world.

Answer 33
