Renewable energy is energy that is collected from renewable resources, which are naturally replenished on a human timescale, such as sunlight, wind, rain, tides, waves, and geothermal heat.
Some examples of renewable energy sources are solar energy, wind energy, hydropower, geothermal energy, and biomass energy. These types of energy sources are different from fossil fuels, such as coal, oil, and natural gas.
The most efficient forms of renewable energy geothermal, solar, wind, hydroelectricity and biomass. Biomass has the biggest contribution with 50%, followed by hydroelectricity at 26% and wind power at 18%. Geothermal energy is generated by harnessing the Earth’s natural heat.
Renewable energy also helps conserve the nation’s natural resources. Renewable energy provides reliable power supplies and fuel diversification, which enhance energy security and lower risk of fuel spills while reducing the need for imported fuels. Renewable energy also helps conserve the nation’s natural resources.
Renewable energy technologies are clean sources of energy that have a much lower environmental impact than conventional energy technologies.
Renewable energy in South Africa is energy that is obtained from renewable resources, those which naturally replenish themselves, such as; sunlight, wind, tides, waves, rain, biomass, and geothermal heat. Renewable energy focuses on four core areas including; electricity generation, air and water heating/cooling, transportation, and rural energy services.
