Question 5

What are the 3 ‘properties’ of renewable fuels?

Answer 5

1) They will never run out
2) Most of them do damage to the environment but in a less nasty way than non-renewables
3) They don’t provide much energy and some are unreliable because they depend on the weather

Question 6

Energy sources can be [ ] to drive [ ] in power stations. Most of the electricity we use is [ ] from [ ] sources of energy in big [ ].

Answer 6

burned
turbines
generated
non-renewable
power stations

Question 7

Describe the process of power stations

Answer 7

1) The fossil fuel is burned to convert its stored chemical energy into heat energy
2) The heat energy is used to heat water (or air) to produce steam
3) The steam turns a turbine, converting heat energy into kinetic energy
4) The turbine is connected to a generator, which transfers kinetic energy into electrical ennergy
