Q.1
What is an advantage of nuclear power?
  • Radioactive waste produced
  • No CO2 or SO2 produced
  • Costly decommissioning process
  • Long start-up time
Q.2
What is an advantage of overhead electrical lines compared to underground lines?
  • Cheaper to repair
  • Affected by weather
  • There is no advantage to using overhead lines as opposed to underground
  • Overhead lines produce more electricity
Q.3
What is an advantage of using water pumped storage systems?
  • Uses less electricity
  • Increases cost of electricity at peak times
  • Creates electricity at peak times enabling demand to be met
  • It creates free electricity
Q.4
How do solar cells create electricity?
  • Absorb light energy from the sun
  • Use turbines which are turned by the wind
  • Turbine turned by water flows through pipes
  • Uses steam produced in the Earth's crust to drive turbines
Q.5
Which of the following fossil fuels has the shortest start-up time?
  • Coal
  • Oil
  • Gas
  • They all have the same start up time
Q.6
What is an advantage of renewable sources of energy?
  • Produce small amounts of electricity
  • There is an unlimited supply
  • High maintenance
  • High initial capital outlay
Q.7
What is an advantage of using gas?
  • Risk of spillage during transport
  • Produce CO2 and SO2
  • Flexible in meeting demand and has a quick start-up time
  • Produce radioactive material
Q.8
Which of the following materials are used in nuclear reactors?
  • Argon
  • Kryptonite
  • Coal
  • Uranium and plutonium
Q.9
What is an advantage of burning coal?
  • Cheap and plentiful supplies
  • Produces more CO2 per unit of energy than oil or gas
  • Causes acid rain
  • Will never run out
Q.10
Why is decommissioning a nuclear power plant expensive?
  • The radioactive material has to be fired into space
  • Radioactive material needs to be disposed of
  • It is no more costly than decommissioning any other power plant
  • The material left over has to be used and this takes time and requires man power to ensure the material is safely burned
