Guiding Question 23.4

What are the drawbacks of using coal?

Why You Should Care

Coal’s widespread use speaks to its advantages: It is relatively cheap and widely accessible and well suited to generating electricity. Its disadvantages come in many different spheres as well—water pollution, air pollution, and ecosystem degradation.

All types of coal mining create overburden that must be removed and piled as mine spoils. Rainwater trickles through this waste and creates acidic runoff that pollutes nearby streams, lakes, and rivers. Once coal is hauled (by barge or train) from the mine to the power plant, burning it releases the most carbon dioxide per ton of any fossil fuel.

Mountaintop removal poses its own set of drawbacks. Not only is there acid drainage, but there are also whole mountains that are clearcut, dug up, and moved to nearby lower elevations. These ecosystems can never return to their original state once their soil layers are disrupted in this way.

Forests can be clearcut via mountaintop removal or damaged by landslides from piles of mining wastes. Forest loss also endangers species like the Cerulean Warbler.
