ELECTRICAL POWER GENERATION SYSTEM - Assignment Example These methods are for the industry of the electric power. Generation of electricity occurs at the power station by the generators of electromechanical, mainly fueled by nuclear fission or chemical combustion to drive the heat engines. Other means like wind and flowing water are used to generate kinetic energy (McKenna, 2009). The other sources of energy are inclusive of geothermal power and photovoltaic. Following the development of AC transmission power, the main power stations became practical economically. This was through the use of the transformers to transmit power with low energy loss at a high voltage. The first power plant was run on coal or water, and in the present the main reliable energy sources are nuclear, coal, hydroelectric, wind generators, petroleum and the natural gas. The other which is not relied much on is as follows; tidal power, solar energy and solar energy. This is the process of utilizing extracted steam or exhaust from a turbine for the purpose of heating, for example distilling petroleum in building heat or refinery. Prior to the introduction of the power stations, the commercial buildings and the big hotels would generate their very own power. (iv) Induction of Electromagnetic , in which case there is a dynamo, electrical generator or an alternator that change energy of motion which is kinetic energy into electricity. This is the most common form of generating electricity and has its basis on the law of Faraday. Turbines are all operated by the fluid that is acts as a middle carrier of energy. Most of the mentioned engines of heat energy are turbines. The other turbines types are driven by the falling water or wind. The sources are as follows:- (a) Geothermal power. Where hot water evaporates a boiling a liquid that is boiling for the creation of steam for driving the turbine. The turbine can also be driven by the underground steam which is under

Liberalism and Realism Essay Example | Topics and Well Written Essays - 500 words

Liberalism and Realism - Essay Example Realists are more of pessimists in international politics. They agree that it is desirable to have a peaceful world. They view no possibilities of escaping the harsh world that is dominated by insecurity, war, and competition. The need to create a peaceful world is a good but not a practical idea. They also have three beliefs that form their basis. They regard states as the main actors in the world of politics. Great powers shape and dominate international politics as well as being the cause of wars. Realists also believe that the external environment influences the behavior of the great powers. In principles, great powers resemble billiard balls whose only variation is in size. Third, realists consider that power calculations dominate the thoughts of states. States always engage in competitions for power. The competition at times demands the need for war and it is at times considered as a good weapon of statecraft. Zero-sum quality brands the competition that makes it intense and un forgiving. States occasionally cooperate, but they have conflicting interests at their roots. The two theories have various common aspects from which they base their arguments. First is the distribution of Power. It refers to the state’s ability to manage outcomes. It is the ability of state B to get state A do something with state A having no options about it. The second one is war. War is a state-directed violence or violence across state borders. The third aspect is the national interest that makes states do what they prefer.
