Annually-30 billion barrels of petroleum is being consumed worldwide. In this busy society, transportation is vital and, for transportation, petroleum is a requirement. All the major forms of business, agricultural, exports and imports depend on transportation. There are three forms of major transportation: by ground, air and sea. These transportations require petroleum to function. Vehicles in the road require gasoline/diesel, airway transportation requires aviation fuel and sea transportation requires fuel oil and other forms of fuels. For not only transportation but, petroleum is required to make all kind of daily use plastics. If the consumption of petroleum continues this way, it will be finished in the near future. Emissions released from evaporation and combustion of these fuel contribute to many environmental and health problems, including emitting greenhouse gases that contribute immensely to global warming. Annually-7 billion tons of carbon is released to the environment due to burning of petroleum. Moreover, when the plastics are discarded into the landfill, it becomes waste plastic and since plastic is non-biodegradable, it can remain in the landfill for a long time. Waste plastics presence in the landfill causes environmental problems for example, it can cause soil to decay, pollute underground water resource and cause land to be infertile. Alternative source of energy created from solar, wind, hydrogen fuel, biomass fuel, bio-diesel, green diesel, bio-ethanol, and geo-thermal has been proposed as a solution to these problems and in future with further research, these alternative sources will play an important role in the field of alternative energy. 展开更多
