Abstract
Energy participates with the most important role in the modern
civilization. Mankind used the traditional energy sources like fossil as
energy source from millions of years up to now [1]. 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].
