Renewable energy, can be defined as energy generated from naturally replenishing and essentially inexhaustible sources. These energy sources take advantage of solar radiation, wind, rain, waves, tides, and geothermal heat. Renewable energies provide a sustainable and environmentally beneficial alternative to non-renewable energy sources like fossil fuels, which are finite and cause environmental deterioration.
Harnessing the power of the sun, solar energy is a limitless source of power that can be used to generate electricity, heat, and light.
Energy is captured by turbines, wind energy is a clean and renewable resource that converts the kinetic energy of wind into mechanical power
Generated by the movement of water, hydropower is one of the oldest power sources on Earth that can be tapped for electricity.
Biomass energy comes from organic material and is a versatile and sustainable source of renewable energy
Non-renewable energy sources, also referred to as finite energy sources, are those that are not naturally replenished on a human timescale and require a longer time frame to replenish. These non-renewable energy sources include fossil fuels such as natural gas, oil and coal as well as nuclear energy. Non-renewable energy sources have played a pivotal role in meeting the world's energy demand for centuries and are still critical part of energy generation presently as well as in the foreseeable future.
Fossil fuels such as coal, oil, and natural gas, are the most widely used energy sources today. They are formed from the remains of ancient plants and animals and release greenhouse gases when burned.
Nuclear energy, produced through the process of nuclear fission, generates significant power and emits no carbon during operation.
Coal is a dominant source of energy in South Africa, providing over 70% of the country's electricity. The combustion of coal releases significant amounts of CO2, contributing to climate change.
Natural gas is increasingly important in South Africa's energy landscape, used for electricity generation and as a feedstock in the industrial sector. It offers lower emissions than coal but still contributes to greenhouse gases.
