COAL ENERGY

COAL ENERGY is vital for the economy of the United States. COAL is a non-renewable fossil fuel source of energy. Coal is the largest source of energy for electrical power generation worldwide. With the latest clean coal technology, it is possible to burn coal with very minimal impact on the environment. With the use of advance filtering, ash and particles collection from the exhaust gases after combustion in their path to the stack or chimney the elimination of most pollutants is achievable. The latest technology makes use of a bag house and hoppers, absorber equipment, and electrostatic precipitators for cleaning the burnt coal gases before they exit to the atmosphere. According to the US department of Energy the cost of generating electricity using coal technology range between 74 and 88 US dollars per megawatt hour (2007).
