“Natural gas is the cleanest fossil fuel and a highly efficient form of energy. Natural gas has many advantages over other fuels. It has fewer impurities, is less chemically complex, can save cost and its combustion results in less pollution. There are many reasons for this increased confidence on natural gas to generate electricity. While coal is the cheapest fossil fuel for generating electricity, it is also the dirtiest, releasing the highest levels of pollutants into the air.
