ZIMSEC O Level Geography Notes: Natural Resources:Energy: Classification of energy sources
One way of classification is by grouping energy sources into traditional and modern sources.
Wood fuel Water (HEP)
Charcoal Nuclear power
Straw/grass Geo-thermal power
Crop residues (stalks) Thermal power from coal, oil and natural gas or wood
Cow dung Tidal power
Some sources and types belong to both groups.
For example canoeing down a river uses the force of the moving water, a very ancient exercise indeed while a hydro-electric power station utilizes water to generate electricity.
Another method of classification energy resources is to divide them into two groups, renewable and non-renewable.
Renewable energy sources are those which are infinite and replenish or regenerate themselves naturally as long as they are not over exploited.
Non-renewable energy resources are exhaustible, getting used up and running out with more exploitation and use.
Sun (solar) Coal
Water Natural gas
Wood Tar sands
Grass/straws Nuclear (uranium, platinum, strontium, iridium)
Energy sources like wood, though renewable, may be exhausted through over-exploitation and overuse.
