FAQ: How is electricity generated from coal? Eland Cables

Firstly, coal is mined from the ground, and transported to the power plant. In most circumstances it is finely ground, turning it into powder that burns better, and then burned in a furnace. The heat from the furnace heats water, generating steam that is used to turn turbines which generate electricity.
