When plants are grown they take in carbon dioxide from the atmosphere during photosynthesis, but when biofuel is burned it releases carbon dioxide back into the atmosphere. 

A company manufacturing biofuels claim that they are carbon neutral. 

Why is this claim considered to be controversial?

  • Because if the land used to grow the crops had been used to grow food produce instead, the same amount of carbon dioxide would have been removed from the atmosphere but none would have been emitted back into the atmosphere

  • Because fertilisers and pesticides are used to grow the crops which are harmful to the environment

  • Because the farming of biofuel crops is labour intensive so they cost a lot to produce

  • Because farming biofuel crops year on year on the same land depletes the land of soil nutrients

The diagram below shows how a solar cell produces electricity using energy from the sun.

Energy is transferred by radiation to the silicon layer of the solar cell causing charges to move. This movement of charges produces a current. 

1-8-mcq-h5

The efficiency of a solar cell is far below 100%. 

Which of the following statements does not account for wasted energy?

  • Reflection from the external connections and plastic cover

  • Absorption by the the external connections, plastic cover & back plate

  • Absorption by the charges

  • Transmission through the back plate

Which statement best describes the differences between solar cells and solar panels?

  • Solar cells use energy from the sun to heat water and solar panels use energy from the sun to generate electricity

  • Solar panels use energy from the sun to heat water and solar cells use energy from the sun to generate electricity

  • Solar cells use the kinetic energy of wind to produce electrical power and solar panels use energy from the sun to heat water

  • Solar panels use energy from the sun to produce electrical power and solar cells store the excess energy
