In South Africa, our most abundant source of energy is coal. Most of our coal is low quality with a low heat value and a high ash content.
Biomass is plant material either raw or processed and includes agricultural residues, wood waste, paper trash, municipal solid waste (MSW),
Internationally, coal is currently the most widely used primary fuel, accounting for approximately 36% of the world's electricity production.
In a hydroelectric scheme, water is stored in a dam and passed through a turbine and generator set before being released back into the river downstream
Nuclear energy is used to produce electricity all over the world. Simply put, nuclear power generation is the harnessing of the energy created by a nuclear reaction.
In a pumped storage scheme, the power station is located between an upper and lower dam. In generating mode, water runs from the upper dam through the station's turbines and into the lower dam where it is stored.
Waves are a free and sustainable energy resource created as wind blows over the ocean surface. The greater the distances involved, the higher and longer the waves will be
For centuries, the energy created by wind has been caught and used for milling, pumping and other things.
