Introduction: Burning coal produces almost 14 billion tons of carbon dioxide each year which is released to the atmosphere, most of this being from power generation. Coal is one of the oldest and dirtiest energy source used today. When coal is burned it releases things such as sulfur dioxide, coal ash, and carbon dioxide. The most harmful out of all of these is carbon dioxide. The release of massive amounts of carbon dioxide causes problems because it is a heat trapping gas that is largely responsible for global warming. The idea of clean coal is to reshape the use of coal and its products. There are many products used to do things like this such as wet scrubbers, coal washing, and digitization but the main one used is called carbon capture storage (CCS). Even with these new technologies of “cleaning coal” there is still major possibilities of harm it causes to the environment and to humans. So, is clean coal really clean? ...
