Step 1: Mining. The first step in the process of generating electricity from coal is to mine it. Coal is typically found in underground mines or in openpit mines. The coal is extracted using large machinery, such as draglines and shovels. Once the coal is mined, it is transported to a power plant via truck, train, or conveyor belt.

Wind power. The principle involved in electricity generation is very much the same as what has been used during the centuries. The only difference is the introduction of an electricity generator. The movement of air is used to propel blades. These blades then turn in the wind and along with it an axle that is attached at the centre of the blades.
