Presently about 90% of human energy demand is fulfilled from the fossil fuels in the form of coal, natural gas, petroleum products, etc. but using such energy sources include many problems because these energy source are non renewable and in its way to be exhausted [2]. Furthermore, burning these fuels emits pollutant gases like carbon dioxide, nitrogen oxides, sulfur oxides in addition to sulfur itself and remains their residuals in the environment. These emitted gases cause the acidic rains which damage plants and animal life and causes many diseases to human. Such gases are also known as green house gases [3]. |
