Man’s biggest achievements is the creation of electrical power. Technology and other innovations made their milestone advances due to electricity. Elecricity fundamentaly is made by burning other types of fuels known as fossil fuels. More recently nuclear fission, vapour, and wind have been exploited as a source of fuel. We now explore the different methods to produce electricity.

One way that’s used to generate electricity is a large turbine. These require motion to produce power and there are numerous of ways that this can be undertaken.

The burning of fossil fuel is used to generate electricity as the blades of the turbine are set in motion using vapour. This is carried out by using huge furnaces that heat enourmous quantities of water thereby producing vapour in the form of steam. Suffice to say that fossil fuels such as gas, coal and petroleum are burnt to heat the water. The amount of pollution that this makes is harmful to the environment as large quantities of carbon dioxide is released in to the atmosphere.

Water is another means used to power the energy producing turbines. This is done by re-directing rivers, streams and other water channels to form a dam. Electricity is then produced when the water from the dam turns the blades that powers the generator. A far more environmentally friendly way because there are no discharges of toxic
elements into the atmosphere. Although the ecosystem of the cachement is adversely affected.

Water as a renewable resource produces 90 percent of the earth’s renewable electricity.

Wind is also a resource that can be harnessed to generate power. It is not necessary to have a large wind farm in order to utilise wind power, because homowners are undertaking their own diy projects to make home power by using wind power which reduces not only energy costs but lessens pollution in the environment too. This step by step simple diy project follows the same method of exploiting wind power to produce electricity with a wind generator.

Portable types can also be used as a cell phone charger.

Electricity can be generated by nuclear energy. This happens under laboritory conditions as neutrons are used to split uranium nuclei into atoms. The heat produced then converts water to vapour which fuels the turbines to produce electricity.

Bio-gas also produces electricity. In some rural countries such as Bihar in India a new method using human waste is employed to generate electricity.
