Nuclear fuels (page 263) 1) What is nuclear power? 2) What are the advantages of nuclear energy? 3) What are the disadvantages of nuclear energy?

Tidal energy Hydroelectric power (page 265) What is tidal energy? Where is a promising site for a tidal station in the UK? 3) Why would tidal power be more reliable than wind power? 4) Give one disadvantage of tidal energy Hydroelectric power (page 264) How is electricity generated using hydroelectric power? 2) Give one advantage of hydroelectric power. 3) Give one disadvantage of hydroelectric power.

Wind energy Wave energy (page 264) 1) What is wind energy? 2) Give an advantage of wind energy. 3) Can wind turbines operate all the time? 4) Name 2 other disadvantages of wind turbines. i) ii) Wave energy (page 264) 1) What form of energy from the waves does a wave generator transfer into electrical energy? 2) Give one advantage of wave energy. 3) Give one disadvantage of wave energy.

Geothermal energy Solar energy (page 267) 1) What is geothermal energy? 2) Give one advantage of geothermal energy. 3) Can geothermal plants be built anywhere? Solar energy (Page 266) 1) What is solar energy? 2) Give two advantages of solar energy. i) ii) 3) Can solar cells generate electricity all the time?

Biofuels Power stations (page 262) 1) What is a biofuel? 2) Why is a biofuel considered renewable? 3) Why is a biofuel considered ‘carbon neutral’? Power stations (Page 272) 1). Coal, oil, gas and nuclear power stations all have different start up times (time taken until they start producing electricity). Put them in order of shortest to longest start up time. (shortest) 2) 3) 4) (Longest) 2) Two of these power stations are not turned on all the time, but are only used to generate electricity at peak times. Which two and why?
