Introduction

Druga gimnazija Sarajevo Essay Power stations in BiH Eldin Hajric 08.12.2010 A power station is a facility which is used to generate electric power. iAt the center of nearly all power stations is a generator, a rotating machine that converts mechanical energy into electrical energy by creating relative motion between a magnetic field and a conductor. In Bosnia there is a lot of hydro power plants, the biggest ones are: Grabovica, Jablanica, Salkovac, Visegrad etc. There are three different types of power plants, thermal power plants, hydro power plants and solar power plants. In order to make our lives and the lives of our offspring better, we need to investigate and design new greener ways of converting mass amounts of energy into electricity. Solar power plants use an endless power, which is the sun. Beams from the sun hit mirrors which convert the suns energy into electricity. Approximately, every 7.2 hours, 3.6kWh electricity is produced. Solar power is clean and green and it can provide enough energy. ...read more.

The main idea behind these power stations is to convert the energy of flowing water into the flow of electrons or electricity. Most hydroelectric stations use either water diverted around the natural drop of the river such as a waterfall or rapids. In addition to this a damn is also built across the river to raise the river to create the drop needed to provide a force. Water in the higher level is collected in the reservoir, which flows into the pipe called the pen star which carries it down to a turbine water wheel at the lower water level. The water pressure increases as it flows down the pen star, it is this pressure and flow that drives the turbine which is connected to the generator. Inside the generator is the rotor which is spun by the turbine. Electro magnets are attached to the rotor located within coils of copper wires called a starter. AS the generator rotors spin the magnets, a flow of electrons is created in the coils of the starter. ...read more.

Conclusion

the waste that comes out of these plants are often dumped into the rivers or oceans, this kills a lot of marine wildlife which local farmers depend on. These power plants also affect our environment; they can both help and destroy our environment. The waste produced in power plants is often thrown out in the forest, or lakes and seas. On the other hand solar and wind power can help with the environment by providing a clean way to get energy. Word count: 1082 AOI: CS- The energy that we get from power plants serves the community on a daily basses, by providing electricity people can do get on with their lives. ENV- Power plants have a serious effect on our environment, they can help and help to destroy our environment. i Fuel, By. "Power Station." Wikipedia, the Free Encyclopedia.
