What to Focus On

  • Fossil fuels formed from buried remains of plants and animals.
  • Coal, petroleum and natural gas are non-renewable sources of energy.
  • Oil is the most widely used fossil fuel.

  • Renewable sources are replenished naturally.
  • Non-renewable sources are limited.
  • Biogas, solar, wind, hydro, waste energy and tidal energy are renewable.

  • Nuclear energy comes from changes in the nucleus.
  • Radioactive atoms emit radiation.
  • Nuclear fission is exothermic.

Common Mistakes to Avoid

Coal, petroleum, and natural gas are renewable because they are natural fuels.

Biomass and fossil fuels mean the same thing because both come from old plant material.

Natural gas is mainly a liquid fuel because it is used for cooking and vehicles.
