The world currently faces a major problem. This problem is the need for alternative energy sources which can be converted into electricity because the main energy source currently used is coal and the coal deposits will not last forever. The main alternative energy sources that many countries are currently researching are wind, solar, hydro and nuclear. But there is another source of energy that is heavily debated to see whether the pros outweigh the cons. This energy source is natural gas. The main reason for the heavy debate is not the energy source but rather the mining of the energy source through the process of hydraulic fracturing. In this report the following topics will be discussed to get a better understand of natural gas and the hydraulic fracturing process. An overview of natural gas will be discussed. A detail description of hydraulic fracturing process will be provided. The advantages and disadvantages of hydraulic fracturing will also be compared. Finally the report will look at hydraulic fracturing in a South Africa context and weigh all the information before deciding if hydraulic fracturing is advantageous or disadvantageous for South Africa. The greatest problem of the 21st century is the need for clean energy (type of energy that will not harm environment) to help produce electricity. The reason for this is due to the rapid improvement of technological devices such as electrical ovens, geysers, computers, machines in factories etc. These improvements cause the demand for electricity to increase placing a greater burden on the suppliers of electricity. The reason why coal is a problem is not because of coal reserves being depleted but due to the effects that coal power station has on the environment with all th... ... middle of paper ... ...2014] Shell 2001.
