OPTION C- ENERGY

ESSENTIAL IDEAS

• Societies are completely dependent on energy resources. The quantity of energy is conserved in any conversion but the quality is degraded.
• The energy of fossil fuels originates from solar energy which has been stored by chemical processes over time. These abundant resources are non- renewable but provide large amounts of energy due to the nature of chemical bonds in hydrocarbons.
• The fusion of hydrogen nuclei in the sun is the source of much of the energy needed for life on Earth. There are many technological challenges in replicating this process on Earth but it would offer a rich source of energy. Fission involves the splitting of a large unstable nucleus into smaller stable nuclei.
