A Study on the Impact of Coal Use - Essay Example This obtained from coal which is aà combustibleà darkà or dark brown sedimentary rock that occurs within the rock strata. This is in vain layers referred to as coal seams or coal beds. It is this rock mined toà produceà theà requiredà industrialà energyà through its combustion. Coal primarily comprised of various elements like carbon, sulphur, oxygen, hydrogen and nitrogen among other elements. These elements emitted to the atmosphere upon combustion of coal causing various adverse environmental and health effects.à This is also true for the other alternative fossil fuel sources of energy such as wood energy, petroleum, hydroelectric and nuclearà energyà whose consumption trends in the U.S has been on a constantà riseà from 1775-2010, (appendix 1), (Kristina, 6). ... This is a combined statistic forà industrialà and residentialà consumption.

This is also true for environmental consequences including climate change and global warming. In the process of coal use, various forms of harmful environmental gasses produced such as carbon dioxide, sulphur dioxide, and oxides of nitrogen and from such emissionsà componentà hayrides and nitrides such as sulphur nitrate and hydrogen cyanide produced (James, 1-4). Theà emissionà of such gasses into the atmosphere contribute to theà aspectà climate change that poses aà considerableà challenge to the survival of the planed and can also lead to the production of acid rain; reaction ofà rainà water molecules and sulphur trioxide in the atmosphere, which also has significant effects to the vegetation.
