National and global energy resources

Question 1

Define a ‘Non-renewable’ energy resource

Answer 1

Energy resources that will run out and cannot be replenished

Question 2

Give an example of a non-renewable energy resource

Answer 2

Fossil fuels: coal, oil, gas
Nuclear power

Question 3

What are the 3 fossil fuels?

Answer 3

Coal
Oil
Gas

Question 4

What gases are released when burning fossil fuels?

Answer 4

Carbon dioxide
Sulphur dioxide

Question 5

Which gas is released in coal mining?

Answer 5

Methane

Question 6

Define a ‘Renewable’ energy resource

Answer 6

Energy resources that will never run out or can be replenished as they are used

Question 7

State 6 examples of renewable energy resources

Answer 7

Solar power
Wind turbines
Tidal power
Hydroelectric power
Geothermal energy
Biomass/Biofuel

Question 8

State 3 ways that energy resources can be used

Answer 8

For heating
For transport
For electricity generation

Question 9

Explain the environmental impact of using fossil fuels ?

Answer 9

Burning fossil fuels release carbon dioxide
Carbon dioxide is a greenhouse gas so it contributes to global warming

Question 10

What is the environmental impact of using nuclear fuels?

Answer 10

Nuclear power produces dangerous radioactive waste
The waste is hazardous to human health and cannot be disposed of

Question 11

Explain why tidal power can be used to produce electricity reliably

Answer 11

The tides rise and fall every day so large amounts of water always move in and out of river estuaries

The waves mover predictably at similar times each day

Question 12

Describe the negative environmental impacts of hydroelectric power stations

Answer 12

A lake must be formed to store large amounts of water and as a result:
Habitats are destroyed
Farmland is lost

Question 13

Give one advantge of hydroelectric power

Answer 13

Energy can be stored and water can be released at times of high demand for electricity

Question 14

Explain why wind power may be considered an unreliable energy resource

Answer 14

It cannot produce electricity constantly; if the wind is too light little power is produced

Question 15

What are the 7 energy resources?

Answer 15

Wind
Tidal
Hydroelectric
Fossil Fuels
Nuclear
Biofuel
Geothermal

Question 16

State the pros of solar energy

Answer 16

Don’t need much maintenance
Produce no CO2
Can be placed in remote locations

Question 17

State the cons of solar energy

Answer 17

Only work during the day
Don’t produce alot of electricity if the intensity of light is low
Solar panels take large amount of space

Question 18

State the cons of using hydroelectric power as an energy resource

Answer 18

Flooding is required
Expensive

Question 19

State the pros of using fossil fuels as an energy resource

Answer 19

Reliable
High energy density

Question 20

State the cons of using tidal energy resource

Answer 20

Danger to marine life
Not 24hr

Question 21

What are the pros of using biofuel as an energy resource?

Answer 21

Cheap
Renewable
Carbon neutral
