Renewable energy is energy that comes from sources that are restored naturally on a human timescale. This includes: sunlight, waves, tides, water, rain and geothermal heat. Roughly 16% of the world’s energy consumption is supplied by Renewable sources.

Wind Energy
Wind energy is the form of renewable energy that converts the wind energy from the wind currents into energy that can be useful to man. This is done using windmills (for mechanical energy), wind turbines (for electricity), sails (to direct ships) and wind pumps (for drainage or water pumping).
A wind turbine converts the kinetic energy given off by the wind current into electrical energy.

Hydroelectric energy
Hydroelectric energy is the form of renewable energy that converts the gravitational energy of falling or flowing water into electrical energy. Hydroelectric energy is the most popular form of kinetic energy in the world, generating around sixteen percent of the globe’s electricity and is used in one hundred and fifty countries. The general cost of hydroelectricity is relatively low, giving it a competitive edge in the market of renewable energy. However the damn that are required for hydroelectric energy can often damage the surrounding wildlife and ecosystems.
The majority of hydroelectricity is sourced from turbines driven by the potential energy of dammed or flowing water. The amount of power that is able to be extracted from the water depends on the difference of height between the turbine and the point where the water is falling or flowing.

The majority of South Africa’s electricity is sourced from fossil fuels such as Coal and Uranium. These sources are not not renewable and are damaging towards the environment. Due to the fact that fossil fuels are ...

...er issues that are not natural include the lack of experience with renewable energy products. In addition to these barriers, the cost of the required necessities to make renewable energy a possibility go beyond the country’s funding.

The Barrier of Finance plays a large role in the option of Renewable energy. The factors of an uncompetitive market and transactional costs may prevent renewable energy from becoming an option for South Africa

Essay about Renewable and Non Renewable Energy

- Energy can be put into two broad categories Renewable energy and none renewable energy. Renewable energy sources can be reused continually as they are abundantly found in nature. All of them are non-polluting but devices used to collect the energy may impact the environment adversely. They are free but producing storage equipment or converting them into another form of energy may be costly. The examples of using renewable energy are The Solar Panel which is an assembly of solar cells. The solar cells convert solar energy into electrical energy....   [tags: wind turbine, coal]

Economic And Political Landscape Of South Africa Essay

- Large-scale Gold Mining, and later industrial manufacturing, molded the economic and political landscape of 20th century South Africa. The need for cheap, low-cost labor created the necessity for black laborers within the concentrated mining and manufacturing areas in the Transvaal and the East Cape respectively. However, the racial climate of South Africa meant that the conflicting interests of whites in power, as well as the black South African population, would regularly find themselves at odds over government policies created by the racial-infused politics of early South Africa....   [tags: South Africa, Black people, White people, Africa]
