Coal is one of the most extensively used non-renewable sources of energy in the entire world. It retains the credit of being known as the precious resource material since ancient times and in true terms acts as a valuable asset to its manufacturers and suppliers.
It still remains one of the most popular means of extracting energy in the world. Coal is related with every industry either as a key integral part of manufacturing, processing, transportation or as raw material. Whether you live in the United States, Dominican Republic or any other part of the world, coal is most likely used to heat up your house during winter.
Coal power is one of the first types of power sources uses to create electricity and other forms of energy. In today's society coal is utilized for energy by combustion or burning. About 65% of the world's coal is used to provide electricity.
Unfortunately there are many environment disadvantages to using coal power. Coal releases the greenhouse gases like carbon dioxide and methane which are the big and main causes of global warming. This global warming involves greenhouse effect process by which radioactive energy leaving a planetary surface is absorbed by greenhouse gases thus warming the earth's surface. (When coal is burned, it produces sulfur dioxide and nitrogen oxide, which produces acid rain and smog).
It is true to say and there is no doubt for it that the coal usage leads to pollution in former years. But now a day’s newer coal mining companies are taking steps to assure the environmental aspects and providing better working environment and benefits package for their workers. As oil prices rise, it usually causes other commodities such as coal and natural gas to rise as well, generally at a lesser rate than oil.
