Q.3
Why are on-shore wave generators unlikely to be developed on a large scale?
  • They look really ugly
  • No-one can afford to build them
  • They don't work
  • Habitat destruction
Q.4
What is a renewable resource?
  • A resource that will quickly replenish itself naturally
  • A resource that requires careful management

  • A resource that will last for 100 years
Q.5
Which of the following is a reason for the government of a country paying for research into wave generators?
  • They wish to reduce the country's dependence on foreign supplies of fossil fuels
  • They have a long coastline
  • They wish to reduce the carbon footprint of the country
  • All of the above
Q.6
Where might wave generators be sited?
  • In the middle of oceans
  • A few hundred metres away from the shore
  • On a beach
  • In harbours
Q.7
Which of the following is not a disadvantage of off-shore wave generators?
  • They need to be built to withstand extreme weather conditions
  • On-shore wave generators need to be built in remote locations
  • There are nearly always waves on the sea so they will be constantly in motion
  • You need a lot of them to generate a small amount of electricity
Q.8
Which of the following would be an advantage of building on-shore wave generators?
  • Maintenance would be easier
  • They are all advantages of on-shore wave generators
  • There would be no worries about the wave generators breaking loose at sea
  • It would be a lot easier to get the electricity to the National Grid
Q.9
Which of the following is a technical problem of wave generators?
  • Wave generators are expensive to build
  • It is difficult to scale them up from wave tank models
  • They look ugly
  • It takes many years of research and development to produce a working wave generator
Q.10
In what direction do the floats of off-shore wave generators move?
  • Side to side
  • Round and round
  • Backwards and forwards
  • Up and down
