How Is Coal Converted to Usable Energy? |

Coal is converted into electricity through a complex process that involves steaming, grinding, processing and distribution. The act of transforming coal into electricity is quite a production; coal is first ground to a fine chalky powder and added to combustion chambers of boilers before being burned at higher temperatures to produce hot gas and heat energy.
