A typical-sized 500 megawatt coal-fired electricity plant in the United States puts out each year: 1. 3.7 million tons of carbon dioxide. Carbon dioxide ( CO2 ) is the main greenhouse gas, and is the leading cause of global warming.
While coal mining has long caused environmental damage, the most destructive mining method by far is a relatively new type of surface mining called mountaintop removal, or MTR. Currently practiced in southern West Virginia, southwestern Virginia, and eastern Kentucky, MTR requires stripping all trees from a mountaintop and blasting away the top several hundred feet with explosives.
Coal: Coal, one of the most important primary fossil fuels, a solid carbon-rich material, usually brown or black, that most often occurs in stratified sedimentary deposits, which may later be subjected to high temperatures and pressures during mountain building, resulting in …
After removing the coal from the ground, the miners may send it to a preparation plant near the mining site. The plant cleans and processes coal to remove rocks, dirt, ash, sulfur, and other unwanted materials. This process increases the heating value of the coal.
