Energy Resources Practice Questions Flashcards
The UK is starting to us wind turbines to generate more electrical energy.
Some people think that this is a good idea, others do not.
Suggest why people think that building more wind turbines is a good idea. (3 marks)
1 mark: ‘fuel’ is free / energy source is free
1 mark: wind power releases no pollutant gases
1 mark: wind is a renewable energy source
Suggest reasons why people think that building more wind turbines is a bad idea. (3 marks)
1 mark: wind power is unreliable
1 mark: wind farms are a type of visual pollution
1 mark: people complain about the noise wind turbines cause
The power station can be used to meet surges in demand as it can start generating electricity quickly
Other than a short start up time, give TWO other advantages of a pumped power station (2 marks)
1 mark: stores energy use for later
1 mark: doesn’t produce pollutant gases
Describe the energy transfers that takes place when electricity is generated at a pumped storage power station. (3 marks)
Any 3 of the following
1 mark: The water in the top of the reservoir is gravitational potential energy
1 mark: Then it is converted to kinetic energy when flowing down to the lower reservoir
1 mark: The kinetic energy allowing the turbine to turn
1 mark: Which turns on a generator, converting the energy to electrical energy
In the UK, most electricity is generated in power stations that burn fossil fuels.
Which type of fossil fuel power station as the shortest start up time? (1 mark)
gas
(Transmission) cables and (step-up and step-down) transformers
1 mark: voltage
1 mark: more efficient
1 mark: it will INCREASE
Name one other renewable energy source used to generate electricity that it not wind. (1 mark)
tidal
waves
solar
3000 kilowatts
1 mark: wind speed was not strong
1 mark
