Wave Generators

This GCSE Geography quiz takes a look at wave generators. The demand for energy resources is rising globally but supply can be insecure, for example, conflict in the middle eastern countries could lead to oil shortages. Our traditional energy resources are also finite and at some point in the future, coal, oil, gas and nuclear fuels will no longer be available. The use of fossil fuels as energy resources also releases large quantities of carbon dioxide into the air which may be contributing to global warming. Many industrialised countries have agreed to reduce their carbon footprint.

The impact of these issues has been to promote research into strategies that can increase energy supply and decrease the dependency on the supply of energy resources from outside of a country. The emphasis of this research has been to develop ways of using renewable sources of energy as this helps to solve both problems.

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
The first and last alternatives are economic problems whilst the third is a social problem
In what direction do the floats of off-shore wave generators move?
Side to side
Round and round
Backwards and forwards
Up and down
As the waves pass, the floats of an off-shore wave generator will bob up and down
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
There are many reasons why governments would wish to invest in renewable energy technologies
What is a renewable resource?
A resource that will quickly replenish itself naturally
A resource that requires careful management
A resource that is mined in Australia
A resource that will last for 100 years
The key here is quickly. Coal, oil and gas will form again at some point in the future, however, the time scale for that to happen is millions of years
Which of the following would be an advantage of building 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
Maintenance would be easier
They are all advantages of on-shore wave generators
They are also simpler and cheaper to build
What is the name given to the floats used in wave generators?
The first floats used for wave generators resembled a duck's head
Where might wave generators be sited?
In the middle of oceans
A few hundred metres away from the shore
On a beach
In harbours
In the middle of an ocean would be no good because it would be hard to anchor the generators and to get the electricity back to the shore. On a beach would be no good as there would only be waves at high tide. If they were in harbours, they would get in the way of boats and ships
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
To get a lot of electricity from wave generators would require large numbers to be built. Large areas of seashore would be damaged and building new access roads to get the people, materials and equipment there to build and maintain them would also destroy wildlife habitats
Which of the following countries is least likely to invest in wave generators?
The UK
Tibet is surrounded by land, the others are all entirely surrounded by sea
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
Make sure that you know the benefits and drawbacks of all of the renewable enrgy resources that you have studied
