What is the process of electricity generation and where can i find a block diagram of the process from fuel

input to electricity output?

Since the majority of electricity World-wide is produced by burning coal, I give you the following text and schematic or block diagram...

My uncle lost half of his foot in a coal mine. My cousin, after a 20 year TOP SECRET military career was not earning enough retirement income. So he went to the coal mine. A whole "room" collapsed or caved-in on him. The undertaker asked for a picture and was crying because he couldn't make him look like himself for the funeral. My father sneaked me on board his freight train and let me run it at 55mph with empty cars. On the way back from the mine on the pitch black night, I could just see the first 200,000 pound coal car rocking and swaying 20 feet from me.

For the additional question you added; a clear explanation of electric generation, do a search for the Left hand rule for the basics and then search for electric generators in power plants.

The process of electrical generation is produced with magnets basically. It is in the form of D.C. and inverted to A.C. The use of the word "fuel" is not proper since a lot of the power produced around the world is done with water and wind. A.C. travels much further then D.C. before needing to be boosted so it is preferred over D.C. for transmission.
To find a block diagram you just have to enter "electrical production block diagram" in to a search engine such as yahoo, google or any other.
