Negative Effects of Coal Fired Power Plants Example

How Do Coal-Fired Power Plants Work? A coal fired power plant is the most inefficient source of energy; it is costly and environmentally hazardous. This is how it works: Firstly the coal is dig from the mines and is supplied to the location where the coal-fired power plant is set up. This supply is made through a highway truck, railways or a barge.
