Background Living organisms are dependent on energy. Chemical energy is formed through the conversion of sunlight by organisms such as bacteria and plants. It is through this process that food is formed for other organisms. Nature only consumes the amount of energy supplied by the sun. A part of the solar energy consumed by nature (animals, plants and their habitats) is transformed into chemical energy and is sealed off eternally from the atmosphere, stored as biomass. 80% of our current energy requirements are met by fossil fuels such as coal, oil and natural gas. Biomass material was converted into fossil fuels millions of years ago. Due to the time it took to form these fossil fuels, it is not possible to rely on these materials to continue meeting the needs of consumption. This means that fossil fuels will either become depleted or be too uneconomical to recover. Appropriate actions must be taken to ensure equilibrium between renewable and non-renewable energy sources as the change of fossil fuels into a usable form emits carbon dioxide, damaging the climate (Nijhoff 1979:35). Solar radiation, planetary energy and geothermal energy are the three forms of renewable energy available on earth. Radiation from the sun is the highest source of energy and the obtainability of these sources alters. In a nuclear fusion process in the sun, hydrogen is transformed into helium. It is in the form of electromagnetic waves that the surface of the sun radiates this energy. This will
