Question

Give a brief account of the uses of coal

Answer 1

What do we use coal for ? But to have trains ! Of course coal use is not limited to this application, but this introduction is only half a joke, because the three main usages of coal, in the world, are, by decreasing order of importance :

electricity generation (2/3 of the world coal consumption), electricity being used for a number of things… including powering trains,steel manufacturing (about 7% of the world coal), which is then used to build trains, rails, and concrete irons that are themselves used to build stations and tunnels,cement manufacturing (4% of the world coal), also used to build stations and tunnels.
