Conventional and Non-conventional Sources of Energy

Coal: Without any second thoughts, coal is indeed the most vital source of energy. The formation of coal takes place when dead plant matter decays into peat (accumulation of partially decayed organic matter or vegetation) which is converted into coal by pressure and heat over millions of years. Coal is mostly composed of Carbon.
