Generating Electricity

Question 1

How do we generate Electricity from a non-renewable source?

Answer 1

Fossil Fuels are burnt to release energy

Boils water to produce steam

Steam turns turbine which are attached to electrical generators

A jet turbine heats air instead of water giving it a start up time

Question 2

How does nuclear fuel generate electricity?

Answer 2

A reactor is used to generate heat by nuclear fission

Heat exchanger is used to transfer heat energy from the reactor to the water

Turns steam and drives turning

Question 3

What are biofuels used for

Answer 3

Biofuels are burnt to release energy. Plants grow quickly, fuels which are burnt can be replaced

Plants and animal waste from farming can also be used as biofuel

Question 4

What are the Non-Renewable energy sources?

Answer 4

Coal oil and gas are formed over a million years from plants and animals.

Question 5

What’s nuclear fission?

Answer 5

Nuclear fission is the splitting of a nucleus releasing neutrons that collide with each other

Question 6

Answer 6

No pollutant gas

Can be offsure

Question 7

Disadvantages of wind turbine

Answer 7

Expensive

Question 8

Tidal waves advantages

Answer 8

No fuel required

Question 9

Tidal wave disadvantages

Answer 9

High building cost

Question 10

Hydroelectric advantages

Answer 10

Fresh start up time

Question 11

Hydroelectric disadvantages

Answer 11

Destroys habitat

Question 12

Solar advantages

Answer 12

No pollutant gases are produced

Question 13

Solar disadvantages

Answer 13

Non rechargeable batteries

Question 14

Advantages of renewable sources

Answer 14

No fuels cost

No chemical pollution

Question 15

Disadvantages of renewable sources

Answer 15

Expensive

Takes space

Question 16

How is carbon capture generated?

Answer 16

Carbon dioxide into gas fields displacing natural gas

CO can also be pumped oil fields

Which makes oil under pressure easier to extract

Question 17

What’s the national grid?

Answer 17

Is where electricity can be generated all over the country by a network of cables

Question 18

What are transverse waves

Answer 18

Oscillations are perpendicular to transfer energy

Question 19

Oil advantages

Answer 19

Easy to Obtain

Question 20

Oil disadvantages

Answer 20

Produces CO2

Question 21

What’s the process of Carbon capture?

Answer 21

CO2 can be pumped into a gas field displacing the natural gas

Carbon Dioxide can be pumped into oil fields which keeps oil under pressure which is easier to extract

Question 22

What are the national grid method?

Answer 22

Electricity generated all over the country by a network of cables

Transmitted through national grid where it is economically viable

Small scale production provides electricity to the grid

Question 23

What are overhead powerlines advantages

Answer 23

Cheaper and they cross roads and rivers

Question 24

Where are underground cables used in?

Answer 24

Tall buildings and for safety

Question 25

National grid order

Answer 25

Step up

Powerlines

Step down

Houses generate
