Electricity is the flow or potential of electrons , it is produced using 1) hydro electricity (water flows from dam to propel a water wheel connected to an electric motor(alternator) , 2) using burning coal in coal fired stations (uses burning coal to heat water in to steam ,which steam then turns a gas turbine that is connected to an electric generator/alternator 3) using windfarms (uses a giant aerodynamic propeller to turn an alternator(electric motor/generator) from the force of wind.
In a coal-fired power station, a boiler burns coal to produce steam. The steam makes a turbine spin. The turbine drives an electricity generator. The electricity from the generator is converted to a higher voltage by a transformer. This higher voltage is to enable transmission over long power lines without losing too much energy. When it comes to reach our homes, it is then converted back into lower voltage by other transformers. Nuclear power stations are similar - instead of a coal-fired boiler, a nuclear reactor creates the steam. Wind turbines use the blades to turn the generator.
I assume you mean electricity produced by burning coal, natural gas, or oil. These are the traditional fossil fuels used to produce heat, steam, and hence electric power.
It's kind of hard to show a flow chart in WikiAnswers - but we can list the steps:Air and coal are fed to the furnace/boiler where the coal is burned. If the power station is attempting to be clean, the exhaust from the furnace is filtered and scrubbed to remove particulates and noxious gasses before being released to the atmosphere (from a smokestack).Water is pumped through pipes running through the furnace/boiler where it is turned into superheated steam - steam under pressure at a temperature above the boiling point for the pressure.The superheated steam is fed to a steam turbine where it turns the blades of the turbine, thus turning the shaft they are attached to. The pressure of the steam drops as it passes through the turbine.The steam that has expanded across the turbine is fed to a condenser where it is cooled and condensed before being pumped back to the boiler. Generally this requires a separate water source (from a lake or river) to be used in counter-current flow to cool the steam. The cooling water is then usually cooled by running it through an evaporative cooling tower before returning it to the lake or stream it originally came from - although it may be recycled quite a bit before being returned.The turning shaft attached to the turbine turns an electromagnet within a wire coil field, generating alternating current (the details of how an alternating current generator works are a different question).Most of the current from the generator is fed to the power grid, with some bled off to power the electromagnet of the generator.
Generators transform energy into electrical energy. The output of the generator is the electric power it "makes". The input is whatever is used to create mechanical energy to turn the "prime mover", or the thing that makes the generator spin (be it steam / thermal energy, water, wind, etc.).

Steam
It is converted to heat first; this heat is then used to produce superheated steam. The pressure of the steam is what drives the electric generators.
Steam, diesel, and electric.
a electric train is faster than a steam engine
South Station in Boston was opened in 1899. It has since been restored. It originally had steam engines, but that caused so much environmental impact it was closed for awhile. It is in use today with restaurants and businesses.

A steam engine requires water to be heated to produce steam. This steam is used in pistons to produce movement, as in a steam train. An electric engine can produce the same energy, as in an electric car, and is far less bulky than a steam engine.
Steam trains were first developed in Great Britain early in the nineteenth century. From the early 1900's they were replaced with electric and diesel trains.
The first steam powered passenger rail service was between Stockton and Darlington (in the UK) and it was opened in 1825.
1801, Richard Trevithick invented the first steam powered locomotive (designed for roads).
