Q

How is geothermal energy generated?

A

in volcanic areas water can be put in pipes over hot rocks to create steam, the steam goes into a generator which is being spun by a turbine

Q

How is coal energy generated?

A

in a boiler, the coal is being burnt transfering its chemical energy into heat energy, that heat is used to boil water and create steam which then goes through a genarator which is being spun by a turbine

Q

How is tidal energy generated?

A

Huge amounts of water move in and out of river mouths each day because of the tides. A tidal barrage is a barrier built over a river estuary to make use of the kinetic energy in the moving water. The barrage contains electricity generators, which are driven by the water rushing through tubes in the barrage.

Q

What can fossil fuels be used for?

A

the chemical potential energy stored in oil, coal and gas can be turned into heat energy by buring them. we can also turn it into electrical energy to use in our homes.

24
Q

What are the advantages and disadvantages of fossil fuels?

A

advantages:
cheap
most used energy resource
using it does not depend on enviromental factors

disadvantages:
Releases CO2 and SO2 (causing global warming and acid rain)
Can be dangerous if used irresponsibily
They are a non renewable energy source

25
Q

What are the advantages and disadvantages of Nuclear fuel?

A

advantages:
No CO2 and SO2 being produced
Very low fuel costs.
Power station has very long lifetime

disadvantages:
Radioactive waste (needs to be disposed of safely)
cost of building is high
Cannot react quickly to changes in electricity demand.
They are a non renewable energy source

26
Q

What are the advantages and disadvantages of Biofuel?

A

advantages:
Renewable
Carbon neutral so low impact on enviroment
Reduce our reliance on fossil fuels.

disadvantages:
Uses land that could be used to grow food.
Needs a lot of labour.

27
Q

What are the advantages and disadvantages of wind?

A

advantages:
Renewable source
Cheap to run (no fuel costs)
No polluting gases produced

disadvantages:
Expensive to build
Noise pollution
can only be used in very windy areas so not reliable

28
Q

What are the advantages and disadvantages of hydroelectrity?

A 
advantages:
Renewable source
Cheap to run (no fuel costs)
No polluting gases produced
Very reliable
Can be switched on when needed

disadvantages:
flooding a large area means people can loose their homes and animals can lose their habitat
Visual pollution

29
Q

What are the advantages and disadvantages of geothermal?

A

advantages:
no poluted gasses
renewable

disadvantages:
has to be in a volcanic area

30
Q

What are the advantages and disadvantages of tidal?

A

advantages:
high poweroutput
renewable

disadvantages:
Building barrages has a significant impact on migratory fish and habitats of sea birds - it can also hinder coastal shipping movements

31
Q

What are the advantages and disadvantages of solar?

A

advantages:
Cheap to run (no fuel costs)
No polluting gases produced

disadvantages:
Dependant on the weather and only available during daylight
It costs a lot of money to make them more efficient

32
Q

What are the advantages and disadvantages of wave?

A

advantages:
Renewable
No polluting gases produced

disadvantages:
could be effect on local habitat

33
Q

Define Non renewable

A

A non-renewable energy resource is one that has a finite supply and it will run out at some stage.
