Power stations today generate electricity from heat, burning a fuel such as coal, oil, or natural gas, or using a nuclear reaction. The heat is applied to water to make steam; the steam expands, spinning a turbine; the turbine is connected to a generator, and the turning of the generator creates electricity. After the steam is used, it is condensed back to water and re-injected into the boiler to repeat the process.

A generator consists of two parts: the main generator, which has windings which are permeated by magnetic field from field coils, and a small generator or alternator called the exciter, which creates electricity to power the field coils on the main generator. In modern equipment, the field coils are on the rotating part, and the main windings are on the fixed part. This makes it unnecessary to run large currents through commutators or slip rings. The generated power is taken from the main windings, typically at around 13,200 volts, and stepped up by transformers in the switch yard for transmission. Generators can be turned by hydropower as well as by steam turbines; some of the generators at Grand Coulee Dam can generate over a billion watts. The electricity generated there is worth over half a billion dollars a year.

I am understanding your question to mean: How is electricity produced from fossil fuels?

OK. Fossil fuesl are carbonaceous, i.e carbon containing, formed by the fossiisation of organic matter including dead animals buried long ago. When carbon (coal) is burnt in air, carbon burns to form carbon dioxide and gives off some heat. This heat is used to boil water and generate steam, which is used to run steam turbine and the mechanical energy of the steam turbine is converted into electricity by the generator, which is basically a big magnet moving inside a coil or vice versa.

And of course, as already exlained by other friends here, there are other ways of producing electricity for example: hydroelectric, wind power, solar, nuclear etc.

Electricity is produced, or generated, by the turning of turbines. In most power plants, these turbines are turned by pressurized steam. The steam is created by the burning of coal or other fossil fuels in massive boilers. In the case of hydroelectricity, the force of rushing water turns the turbines.

There are also wind farms (most modern wind power is generated in the form of electricity by converting the rotation of turbine blades into electrical current by means of an electrical generator), nuclear, some solar, and some geothermal, although there aren't a lot of the latter in the U.S.

Nuclear Powered Electricity is one thing powered Turbines from water is another.

You build a dam and these huge circle tunnels are place from the top and run completely to the bottom of the dam. When the gates open up the water rushes in and within 15 seconds the water level drops like 6 ft.

The water runs downs these tunnels directly to the Turbines that will turn like a windmill and that turns the generators making electricity. Hows that for science?

Fossil fuel stations generate steam to drive turbine which drive the generators.

In hydroelectric plants, water pressure is used to power the generators. There are also wind farms, geothermal, and solar generating plants.

elcetromotive forces are harnessed by many ways. solar and wind are most easy and friendly, burning fuels less so. power stations usually are locations that the electricity has been transferred to and reduced to a form that can be passed down a local wire.

power stations are not were it is generated, just transferred. lots of heat has to be delt with and passed on to the atmosphere, so power stations are seen as these things.

simply electricity is just transformed in power stations.

Mai, putting fossil fuels aside, Australia is between the greatest international locations in harnessing organic materials for potential technology, we are taking a similar course as Australia in no longer utilising nuclear potential, and going the way of hydro technology by organic materials.

No. There is nuclear power, solar power and wind power. Also, hydroelectric power is common in the Western United States.

no and I do not have time to tell you how to generate electricty. Look it up. To get energy you must have a fuel. But there are many kinds of fuel.
