The Sun is the source of energy for most of life on Earth. As a star, the Sun is heated to high temperatures by the conversion of nuclear binding energy due to the fusion of hydrogen in its core. This energy is ultimately transferred (released) into space mainly in the form of radiant (light) energy.

The importance of coal. Calls to decrease the world's dependence on coal as an energy source are well intentioned. Lower use would reduce greenhouse gas emissions, and less demand would lower the environmental risk of coal mining. However, as the world moves away from coal, South Africa will need to consider the implications.
Importance of Energy: (1) Easy availability of energy helps in the process of industrializations in a country. ADVERTISEMENTS: (2) Production of energy leads to the efficient utilization of natural resources. For example solar energy, wind energy and hydro-electricity power can be generated by using sun light, wind and water resources respectively.
