Substrand: "5.3 Energy sources and energy changes" (20 periods)

Energy that we use today comes from many different sources. Some sources may be renewable while others are non-renewable. Renewable energy sources are able to regenerate themselves thus may always be available in the environment e.g. wood, coconut oil. Non- renewable energy sources are finite – they are used up over time. Our planet has a limited supply of energy therefore; energy sources must be used in a sustainable way. Energy can be converted from one form to another. Energy can be transferred in the form of stored energy, kinetic energy or heat energy to other useful forms.
